Questions and answers.13-14.
No. 66. Which was a the first contionuous brake in use in this country?
Fay, Newall and Clark chain brakes introduced in 1860s. Fay & Newall on L&YR and B&MR. Wilkin & John Clark on Metropolitan Railway and LNWR: in case of latter as modified by Webb. Steel & McInnes c1871 introduced a compressed air brake on two Caledonian Railway trains. The system was heavier and more cumbersome than the Westinghouse system. An American John V. Smith took out a British Patent for a simple vacuum brake in 1874. It was improved by Hardy, an Englishman, working in Austria. Sanders and Bolitho invented an automatic vacuum brake in about 1877. Aspinall patented a form in 1878 whilst on the Great Southern & Western Railway.
No. 67. Does notching up a locomotive "very high" cause axleboxes to knock?
Suggested that cut-offs should not be shortened to lessw than 20%.

Correspondence. 14

[Timothy Hackworth]. J.G.H. Warren
The article on Timothy Hackworth in your issue of December 15th contains statements in regard to the loco- motives and working of the Stockton and Darlington Ry., 1825-1827, and in particular in regard to the "Royal George," which are not correct.
These statements are merely a repetition of the fabulous history of that period published many years ago, after his father's death, by John W. Hackworth, who, at the critical time of which he wrote afterwards so assuredly, was about six or seven years old.
Many of these statements have been completely disproved by the official records of the railway company, now pre- served at York, and by the reports of independent engineers who visited the line.
The most important of these—all of which are now available to students are:
(1) The exhaustive report by Von Dechen and Von Oeynhausen, published in Archiv für Bergbau und Hüttenwesen, Berlin, 1829.
(2) The notes by Rastrick, 1829, preserved at the Goldsmiths' Economic Library, University of London. These reports show, inter alia, that the four engines which preceded the Royal George performed duties more than in proportion to their capacity and weight, as compared with the heavier engine Royal George. The normal loads were not as given in your article,
(3) The minute book of the committee of the railway company, which recorded on 10 July 1827, the superior economy of steam to horse traction, as ascertained on the working of the first four engines not less than four months before the Royal George was put to work.
(4) (a) The article by John Farey on Steam engines (in Rees Cyclopredia) 1819. (b) Bulletin de la Societe d'Encouragement d'Industrie, 1815. (c) Woods' Treatise on Rail-Roads, 1825 (first edition). (d) Coste and Perdonnet's report on the Bolton Railway, Annales des Mines, 1829. (e) Woods' Treatise on Rail-Roads, 1831 (second edition).
These authorities show that, so far from the Royal George or Hackworth's later engines having been the first locomotives to embody certain features claimed, the facts are; A six-wheeled engine had been at work before 1819; a spring safety valve was in use on the Blenkinsop-Murray engine in 1815; an exhaust steam feed heater had been applied by Robert Stephenson & Co. early in 1827; wrought iron tyres for locomotives were probably first tried by Nicholas Wood at Killingworth.
As for the "Blast Pipe" controversy, so much has already been written that one is almost afraid to refer to it. The use of the exhaust steam, carried in a single pipe to the chimney, is shown on the earliest known drawings of the Killingworth (or Hetton) type of engine long before 1827; it is shown on a drawing published in 1823, and is definitely recorded in 1825. There is, however, no evidence of a contracted nozzle, which indeed would not have been required with the large straight single flue.
This contraction appears to have been carried out first by Hackworth on the Royal George, which had a return flue, about 2½ times as long as the single flue of the Locomotion type, but a fire grate area by no means in propor- tion to the increased heating surface.
The contraction of the nozzle to meet these conditions was less an "invention than the accentuating of a principle, and moreover, it cut both ways, for it could only stimulate combustion at the expense of increased back pressure. The contracted nozzle was, in fact, an easy remedy obtained by introducing a new disease. If we reflect that locomotive engineers have ever since been struggling to free the exhaust and enlarge the nozzle. we may realise how all sense of perspective and proportion has been lost in this controversy. There are, I think, few locomoti ve men to-day who would consider the contraction of the nozzle as anything but an evil, or who, in their sober moments, would wish to hang a laurel wreath round it as an idol. Timothy Hackworth indeed deserves his statue, as a railway pioneer who accomplished a task of great difficulty with honour to himself and profit to his company; as a designer who added a definite link in the chain of locomotive improvement, and as a man who has left an enduring memory and tradition for personal worth and piety. It is doing ill service to such a man to repeat as history the extravagant statements and claims made for him by John W. Hackworth, no doubt in good faith, but with great bitterness, and since found to be unsupported, or to be definitely contradicted by the evidence of engineers who were responsible men when he was a child.
I would add that I have neither hope nor intention of converting any of your readers who belong to the Shildon school of locomotive history. I observe that they continue to believe the Sans Pareil to have been a better engine than the "Rocket." As the whole subsequent history of locomotive development contradicts such a view, one can only conclude that in questions concerning Timothy Hackworth's work as a designer their critical faculties are in abeyance.

John W. Hackworth and locomotive history. J.G.H. Warren.
After reading Young's letter in February issue, I feel worthy to be counted among the victims of J. W. Hackworth's dialectical umbrella, as depicted in S. T. Richardsons' witty caricature of 1876, and reproduced by Young in his own book, (Timothy Hackworth and the Locomotive," face p. 212.) although it is an obvious satire on certain violent methods of argument.
But the sense of humour which led Young to publish this caricature seems to have deserted him, and he is now very angry with me, though some years ago—in spite of my previously published opinion of John Hackworth's history—he expressed a wish to meet me. I would like to ignore the angry expressions of his letter to you and recollect Mr. Young as the pleasant companion of an hour's discussion when, though I confirmed and emphasised my published opinions of his uncle as a historian, we parted friends.
I am sorry that Mr. Young has brought his family relationship into the present public discussion, for I have been more considerate of it than he thinks, and it has no real bearing on the historical questions raised.
In regard to these, I have nothing to add to my last letter except answers to two questions—or challenges—which Young puts to me:
1. Referring to early six-wheeled locomotives, there is a strong implication from the drawings of Dodds & Stephenson's 1815, and Losh & Stephensons 1816 Patent Specifications, that Stephensorr's early six-wheeled locomotive was coupled throughout, and Farey 's description, published in 1819, states distinctly that the six wheels were applied "to relieve the weight upon the rails and obtain a greater reaction to advance the carriage;" in other words, to obtain greater adhesion (A Century of Locomotive Building, pp. 23, 24.).
2. Referring to feed-heating by exhaust steam, Van Dechen and Van Oeynhausen's report shows that this apparatus had been fitted to a locomotive which was completed before the Royal George was built. This engine was subsequently sent to the Stockton & Darlington Ry., and was called Experiment. John W. Hackworth's account makes out that it was constructed after the Royal George and as a counterblast to that engine (Timothy Hackworth and tbe Locomotive,  p. 163)—a very good instance of his unreliability.
But those of your readers who are interested and so far unbiassed, must study the evidence for themselves—that is all I ask.
To the majority, who are interested only in the "modern side" of locomotive history, John W. Hackworth's merits may well appear as irrelevant as King Charles' Head; but those who, whether for duty or pleasure, commence to study the early history of the locomotives, and working of the S. & D. Ry., will soon find themselves faced with the utterly confiicting opinions of later historians. To them the question of Mr. Hackworths credibility as a witness becomes of the first importance.
My own attempts to resolve this question involved a great deal of work, but they led directly to the discovery of detailed contemporary evidence which seems to have been unknown to previous writers, and is still ignored, or brushed aside by the Shildon school.
To me, and to most of my critics, these evidences have seemed conclusive on the fundamental question we are now discussing. Those who wish for a third, and presumably unbiassed, opinion of Mr. Hackworth as a historian, will find it in The Engineer, 28 September 1923, in an article on "Timothy Hackworth and the Locomotive."

Early locomotives of the G.W. Ry. J. N. Maskelyne.
With reference to the delightful articles by E. L. Ahrons, on the above subject, and particularly with regard to the 481 Class, I am enclosing a photograph of Engine No. 487, which may be of interest. The photograph was taken at Reading in January, 1920, at which time No. 487 was the last survivor of her class, and was usually employed as shunting-pilot at Reading station. A study of the photograph reveals some modifications which must have been made at a later date than those mentioned by Ahrons, and I think that several other engines of this class were. similarly modified, especially Nos. 489, and 588 both of which were well known to me.
The most conspicuous, apparent alterations, are the Belpaire firebox and the somewhat extended smokebox, as well as the shortened chimney. The tender, also, although of an.old pattern, differs considerably from that originally supplied, and has had a raised coping added to the sides of the coal-space. No. 487 had disappeared from Reading in April, 1921 .: and was scrapped at Swindon in July of that year, some two years after all the other engines of her class had been scrapped.

Three-cylinder locomotives.  William T. Hoecker. 134-5
In view of the remarks made at the meeting of the Institution of Mechanical Engineers in Newcastle, last July, it is rather surprising to read, on page I of your January issue, that the new 2-6-4 tank engine No. A890 River Frorne, of the Southern Ry., is equipped with the same design of valve gear that was applied to the 2-6-0 engine, which was built for the same railway several years ago.
The writer had hoped that the matter of " combined valve gears for three-cylinder engines" would be thoroughly discussed at the meeting referred to above, when a paper was read on" Three-Cylinder High Pressure Locomotives," but, beyond a few slight criticisms ,the subject was passed over very lightly, the author of the paper contenting himself with saying that the gear is "giving entire satisfaction." It is, however, significant that he did not see fit to publish any indicator diagrams taken from three-cylinder engines.
There is ample evidence from America and Germany to prove that these combination valve-gears do not give a satisfactory steam distribution in the central cylinder, when the engines are run at a cut-off of less than 50 per cent. It seems to make no difference what kind of combination is used,whether vertical or horizontal levers, whether 8 or 28 pin-joints, the result is always the same, namely: As the speed is increased and the cut-off shortened, the power developed in the central cylinder increases out of all proportion to that developed in the other two cylinders.
There are nearly 2,000 three-cylinder locomotives of 2-10-0, 2-8-0, and 4-6-0 types in Germany, equipped with two different arrangements of combination valve-gear, for the inside cylinder. Some of these engines have been in service since 1914, so that ample opportunity has been provided to observe the performance of the valve-gear, and to make possible improvements. Nevertheless, several hundred of the new Mikado (2-8-2) passenger engines have been built with three separate gears (as illustrated in the LOCOMOTIVE MAGAZINE for September, 1922, pp. 253), because it was found utterly impossible to secure proper steam distribution at high speed with the combined lever gears. Some of the foremost Continental engineers, among them Robert Garbe, and Hans Steffan, have condemned the combination gears used on the Prussian engines in no uncertain terms. These facts are, certainly, well known to you, but apparently, English locomotive engineers are not generally acquainted with them. While on this subject, it may also be noted that after three years' experience with two heavy 4-8-2 type, 3-cylinder goods locomotives, equipped with the combined valve-gear, the New York Central Railroad is now placing in service 100 locomotives of the same type, similar in many respects to the 3-cylinder engines, but having two cylinders only, and using steam at 225 pounds pressure, an increase of 25 pounds over that used in the 3-cylinder locomotives.
This seems to demonstrate that, although the piston loads of a two-cylinder locomotive may be 30 per cent. greater than those of a similar 3-cylinder engine, and the two-cylinder locomotive may be inferior in torque and balance, yet the net results measured in terms of reliability, and cost of maintenance and operation, may be favourable to the two-cylinder type.

Recent Spanish Locomotives. K. Warne. 135
Re article in the December 1925 issue, it is stated a belief that Spain was at present the only country in which 4-8-4 tank locomotives were in service on the standard gauge. May I be allowed to correct this statement. Within recent years the Yorkshire Engine Co. have constructed six locomotives of this type for the standard gauge lines of the Chilian Nitrate Rys.  As these engines were designed by the makers and in view of the knowledge, skill and organisation necessary to pro- duce such an advanced type of locomotive, I think it only fair to point out in these days of self-depreciation the energetic way English locomotive manufacturers have attacked and solved difficult haulage problems by introducing powerful locomotives of such rare design to such distant countries.

The development of the locomotive.
We have received from the Central Steel Co., of Massillon, Ohio, U.S.A., a copy of a nicely finished book they have recently published with the above title. As may be expected, the general tendency of the record is to show that the evolution of the modern locomotive has taken place in America, and, whilst ready to admit that great credit must be attributed to our 'cousins' across the Atlantic for the wonderful stndes made dunng the last ten years in developing the huge power units we now see in service, we cannot accept all they say as being Gospel. We are somewhat surprised such an authority as J. Snowden Bell, who is responsible for literary matter in the book, should say, when referring to the improvements effected in America :-" The first, and doubtless the most radical and universally approved one, was the swivelling truck, in the absence of which high-speed service would be impossible "-(the italics are ours). Surely, Mr. Bell cannot be ignorant of the fact that nearly all the high-speed trains this country became famed for were hauled by locomotives built without bogies, so that it is not logical to say such would be impossible. We fear that Mr. Bell cannot read his LOCOMOTIVE carefully. The illustrations are good, and give attractive represen- tations of the different historical locomotives put on the various pioneer American railroads. Vve regret to note a similar fault as that which seriously discounted the effect of the pictures given in Major Pangborne's book, viz.:-" Engines depicted as running without tenders or trains." The Stourbridge Lion is. shown thus, with the engineman standing on a naked foot-board outside what appears to be intended to represent the Baltimore Station of the day.
Among the other early locomotives shown careering along without tenders or trains are the" Atlantic" of 1832, " Sandusky" of 1837, and the first American 4-4-0 type. Over 50 locomotives are shown, from Cugnot's, of 1769, to the" Horatio Alien," of 1924; but perhaps one of the most interesting illustrations is the frontispiece showing the interior of the erecting shop of the Norris Works, at Philadelphia, about 1855.

A.R. Bennett. New notes on the early locomotives of the L.B. & S.C.R. —1. 155-6.
In July 1918 the Author had several conversations with G. Aylwin of Brighton who spent the whole of his working life in the service of the London, Brighton and South Coast Ry., first as mechanic in the Brighton works and on the Brighton Company's steamers, and afterwards successively as fireman, driver and locomotive inspector. He laboured in turn under Messrs. Craven, Stroudley and Billinton, senior, and there is evidence to show that with the last two his position was one of trust and confidence.
Mr. Aylwin, not always quite content with his subordinate position in the stirring railway world, was ambitious to embody the fruits of his matured experience in locomotive design, and produced two well-executed drawings of engines such as he would have liked to have seen tried on his line. The drawings were commended by Mr. Stroudley, but the ideas, except in one small detail, were not adopted. At the time Mr. Aylwin made his communications to me objections existed to their publication, but these obstacles having recently been removed, they are now given to the readers of THE LOCOMOTIVE with his consent and authority.
Mr. Aylwin entered the erecting-shop of the Brighton works on 8 March 1858, at the age of eighteen. In this shop, when he joined, there was one of the early Sharp Roberts engines, No. 25, built m 1839, mounted on a frame, the wheels being removed, engaged in pumping water and in driving the machinery of both the erecting and boiler-shops by means of a pulley fixed on the driving shaft, work she continued to perform for a good many years. This remembrance throws some light on the little outside-cylinder 2-2-2 saddle-tank No. 25 which worked on the Littlehampton branch in the 1860s. In the very well-known History of the Locomotiues of the L.B. and S.C. Ry. (Locomotive Publishing Co.), at page 91, it says that this tank engine was "built out of parts of a single engine made by Sharps in 1839" (this could only have been No. 25, since no other bore that date). "How much of the original locomotive went into the new one we cannot say, but probably only the wheels and framing." Mr. Aylwin's recollection settles this point, since the original engine, minus the wheels only, was located in the erecting-shop. This accords entirely with the probabilities, for the Littlehampton tank which I knew well (see my Supplement to the Brighton Railway History, THE LOCOMOTIVE, October, 1909), bore no sort of resemblance to a Sharp, Roberts single. No doubt, when the Sharp was well-established in her stationary job, Mr. Craven built the new 25 on her wheels, honouring the ancient motto, "Waste not, want not." Old 25 was the oldest engine but one that fell to the share of the L.B. & S.C. Ry.· on the dissolution of the Joint Committee in 1846, and it is gratifying to be able to trace her to her last employment.
It is to Mr. Aylwin that I owe an interesting fact about the early history of the original Crystal Palace Company. The Palace at Sydenham was opened on 10 June 1854, but at first there existed no proper railway access to it for visitors arriving by the Brighton main line. A spur to the Palace from Norwood Junction had been made for the conveyance of material during construction, but for some reason the railway company did not utilize it for passengers after the opening. These accordingly had to tramp up to the Palace from Penge or Anerley stations. There was good access to the Palace from London Bridge (Victoria did not then exist) by the special spur line from Sydenham, but as there were no main-line platforms at that station, passengers could not change there. The Crystal Palace Company endeavoured to better this state of affairs by running a train of their own from Norwood Junction. To this end they purchased an old Sharp Roberts single and three coaches from the L.B. and S.C. Ry., and with that company's approval, started a shuttle service that continued for several years. They repainted the engine blue, polished her up and put her in charge of a competent driver. Unfortunately, Mr. Aylwin does not recollect her Brighton number—on the C.P. .& N.]. Ry. she was undoubtedly No. 1—but he knew her engineman, and is able to say that the Palace train was still running in 1859, for, in October that year, the engine of a goods train exploded between Lewes and Falmer, killing her driver. This man was a brother of the captain of the "C.P. Sharp," and Mr. Aylwin recollects that he was granted leave to attend the inquest. However, the L.B. & S.C. Ry. eventually condescended to work the Palace spur. The engine was then laid aside, and after a time either sold or broken up. It is a pity that the idea of preserving her amongst the antediluvian relics by the lake did not occur to the C.P. directors; she would be an asset to-day.
Of these early Sharp Roberts engines Mr. Aylwin speaks quite favourably, saying they were very good for their weight, and specially mentions Nos. 20 and 24. They had ceased main-line work when he joined the company, and in the 1860s were mostly performing on the various branches. Several had been turned into frame-tank engines—19 and 77 were two such—and both tenders and tanks worked a good deal between Croydon and Wimbledon, making occasional trips to London (Supplement to the Brighton History, THE LOCOMOTIVE, May 1907). In addition to the duties enumerated in this Supple- ment, Mr. Aylwin says that No. 19 also worked at one time between Polegate and Eastbourne. Another exercising ground for the tender Sharps was be- tween Brighton and Lewes, a duty they shared for max:y years with the smaller type of Jenny Lind engines.
I state in my Supplement to the Brighton History, (March 1908, and May 1908) that in the late 1850's the principal Brighton engines working on the Bricklayers' Arms branch were 112 and 113, built by Longridge, and 44 and 46, built at the Brighton Works; also that a goods train left Willow Walk every evening about 7 o'clock. Mr. Aylwin confirms all this, and says that the exact time was 7-45. A few years later, in the 1860s, he himself drove goods engines to Willow Walk, and frequently worked the 7-45. He also confirms my recollection that it was a heavy train, and agrees that the engines were powerful and did take forty loaded trucks, and more on occasion, up the exacting gradients. He especially commends the Longridges, which had all the wheels in front of the firebox, for pulling.
He often drove the big Sharp, Stewart engines, 117 Orestes and 121 Europa, and agrees, as stated in the Brighton History, page 66, that they were at the time the most powerful in England. With one of them he once took 83 trucks up the New Cross-Forest Hill bank unassisted. The firebox was recessed to allow the trailing axle to pass under it. This caused a horizontal water-bridge, which divided the box into two compartments, and it was customary to keep the forward one fed with coke and the rear one with coal, which had the effect of burning the smoke before it reached the tubes; so smoke was prevented without a brick arch. The orders were very strict about keeping the top of the bridge uncovered by fuel, and whenever the engine was cooled down, to have it carefully examined and swept. There was a wash-out plug in each of the corners of the firebox, and to undo these-wash out with a flexible pipe and nozzle of hot water passed in through the damper, and screw them up again-ensured to the operator the enjoyment of a Turkish bath for which the company charged nothing, but which rendered a good rub down of the temper afterwards, a very necessary procedure. With the water in the horizontal bridge kept away from the top surface by the steam generated, as it probably was, the danger of burning would not appear remote, but no accident of moment was recorded or is remembered. The attention required by the water-bridge was probably found embarrassing as time went on, for Mr. G. F. Burtt informs me that Mr. Craven later on fitted a firebox with a mid-feather and a sloping grate that passed over the trailing axle. This looks like a Cudworth firebox.
It does not seem to have been thoroughly recognised that the admitted and admired superiority of these two engines was attributable to their large boilers and heating-surface (1,572½ sq. ft.), for Mr. Craven continued to build his own goods engines with about 1,000 sq. ft. only, and Orestes and Europa ultimately had theirs cut down to about the same figure, after which there was no more boasting about their exceptional prowess.

Institution of Locomotive Engineers. 156
Paper read at the meeting on 29 April, by T. Grime, member, on Steam Locomotive Performance (theoretical and actual). The author not only gave his investigations as to why certain economies, etc., were to be expected from superheating compounding, etc., but also quoted results from practice which confirmed his deductions. The benefits of "long" travel for the valves, higher steam pressures, etc., were fully discussed, and there is little doubt Grime's paper will figure amongst the most valuable the Institution have so far secured. An animated discussion followed the reading of the paper, after opening remarks by Kelway Bamber, who occupied the chair. Messrs. Clayton, Tritton, Dendy Marshall,. Rogers, Saunders, Poultney, Tomes and Holcroft, took part, .and whilst the speakers appeared to be generally in favour of the attitude taken by the author as regards future development of the steam locomotive, some interesting criticisms were raised.

E.L. Ahrons. Early Great Western standard gauge engines. 156-9. 5 illustrations
Twelve 0-6-0T built at Wolverhampton for freight working: Nos. 633-637 in 1871 and Nos. 638-644 in 1872. Had inside frames and 4ft 6½in wheels and 16 x 24in cylinders, later increased to 17in x 24in at Swindon. Built with weather-boards, later replaced by cabs and these removed for working over Metropolitan Railway to Smithfield. In 1871 No. 56, a 2-4-0 was built at Swindon and this was follwed by Nos. 717 to 726 in 1872: "they were notable for their length". By the time they were withdrawn thhere were marked differnces between those allocaterd to the Southern Division (mainly at Weymouth) and those on the Northern which were "rarely seen south of Bordesley".

Great Western Ry. 159
During 1925, seventy-eight new engines were added to the stock, all of which were built at Swindon. These comprised ten 4-6-0 four-cylinder express engines. of the Castle class, Nos. 4083 to 4092; ten 2-6-0 tender engines Nos. 7320-1, and 6362-69; eleven 2-8-0 tanks, Nos. 5245-55; and forty seven 0-6-2 tanks, Nos. 5603-49. Among noteworthy withdrawals were the three motor-fitted 4-4-0 tank engines taken over from the Taff Vale Ry., and numbered 999, 1133 and 1184 and the 4-4-2 tank No. 4600 built at Swindon in 1913. Several of the ex-T.V.R. older pattern 0-6-2 tank engines have also been taken out of service. During the present year the series of thirty 2-8-0 tank engines, commenced in the latter part of 1925 had been completed, and further 0-6-2 tanks of the 5600 class were now in hand. These to be followed by ten more 4-6-0 of the Castle class, the first of which No. 4093, would shortly be out. Several of the forn:er Midland and South Western Junction Railway locomotives, both goods and passenger, had been rebuilt with Swindon standard taper pattern boilers and superheaters. The tender fuel capacity had also been increased.

Narrow-gauge (2 ft. 6 in.) lines of the Victorian Government Railways. 159-61. 3 illustrations
Though many broad-gauge (5 ft. 3 in.) branch and even main lines run through hilly country and.with.l in 50 and even 1 in 30 grades, there are four lines mto country so mountainous as to warrant the setting up of branches of special narrow gauge, even though the transhipment costs are a senous contra to the plan. These feeder. lines ran from Wangaratta on the main Sydney line to Whitfield (30 miles); from Colac on the Western District lines to Crowes in the coastal forests (43¾ miles).; from Ferntree Gully to Gembrook at no great distance from the capital (18 mles); and from Moe, on the main Gippsland line into Walhalla (26 miles). Except in the case of the first, these lines follow routes that no broad gauge line could penetrate. Locomotives included 2-6-2 narrow gauge Vauclain compound tank locomotive No, 2a and two 2-6-0+0-6-2 Beyer Garratts to work timber traffic

The Aire and Calder Navigation management presented to the museum some early tramway rails and chairs from the Silkstone Ry, of 1809. These were unearthed during work in the neighbourhood of the Barnsley Canal. The Silkstone Ry., of which these rails and chairs formed a part, connected the Silkstone colliery with the Barnsley Canal. The rails are made of cast iron and of the channel type; they are made to accommodate wagon wheels which had no flanges, the rims of the wheels being held by the sides of the channel. The chairs rested on stone sleepers.

Methods for investigating failures of locomotive components.  167-8
The science which enables us definitely to ascertain the causes of failure of any metallic component of a locomotive or, indeed, of any other mechanical structure is comparatively new, and is also a science of extreme importance. In all branches of engineering failures occur, and in many cases, especially when no serious accident or stoppage of traffic happens it is thought sufficient merely to replace the offending part without going to the trouble of finding the exact reason for the breakage. Sometimes the metallic fracture is casually examined by eye or by the aid of a pocket lens, and from the appearance of this fracture a haphazard guess, which is deemed sufficient, is made about the probable cause of failure. Such crude, unscientific, and very unsatisfactory methods are obviously of little value and do not tend to progress either in metallurgy or engineering, which two branches of science are very closely allied. It is now an accepted fact that the exact reasons for failure can generally be discovered, and so it will perhaps be of interest to know how these troubles are diagnosed. In railway engineering in particular such methods are of great importance, not because failures are more prolific in this branch of engineering than in others, but for the reason that locomotive or general rolling stock failures are liable to be attended with more serious consequences than in most other cases.
It will be well to consider the fact that most failures are generally attributed either to fatigue or to crystallization of the metal. Every engineer is familiar with these terms, and possibly because there exists a certain amount of mystery about them, when failure is said to be due to either of these causes it is frequently accepted without question. In point of fact, failures are rarely due to fatigue, and indeed fatigue has been aptly compared with the medical practitioner's influenza, meaning that when causes of failure or illness are not known, fatigue and influenza are very convenient terms to apply to the trouble. Crystallization, on the other hand, is never the cause of failure at normal temperatures because metals do not crystallize at such temperatures. The habitual mistake of suggesting that steel failures are due to crystallization of the metal has probably come about owing to the fact that a considerable number of fractured steel parts exhibit very crystalline structures, and it is sometimes thought that this coarseness has been developed whilst the steel was in use. Steel does not crystallize at normal temperatures; and so, unless the faulty part has been considerably heated whilst in use, one can unhesitatingly say that crystallization is not the cause of failure, and any coarse-grained fracture must have been in the steel when the article was manufactured.
Failures may be due to one or several of the following causes :-(1) Wrong material, (2) Faulty design, (3) Faulty machining, (4) Faulty stamping, forging or heattreatment and (5) bad steel. then proceeds to test methods: microscopy and physical test for hardness

Locomotive superheating and feedwater heating. 170
A supplement to The Lomotive Mag.bearing the above title, had been published by the Locomotive Publishing Co, we venture to think will be much appreciated by railway officials, locomotive engineers, builders, designers and others interested in the steam locomotive. We have endeavoured to incorporate in a convenient volume some account of the early attempts to secure benefits from superheating and economy from heating the feed water. Com- bined with this we have recorded some of the best known modern developments in apparatus; many of these have reached a very practical and efficient stage. Among the pioneers in these efforts to obtain more satisfactory utilisation of the heat units generated in a steam locomotive must be mentioned such prominent names as Cudworth, Beattie, McDonnell, etc., etc. Several illus- trations of the arrangements adopted by these capable designers are included in the book, and form interesting records in the gradual progress of the work of improving the locomotive.
The advent of the Schmidt "fire tube" superheater, of course, represents a notable milestone in the gradual adop- tion of superheating; the recent rapid development is remarkable, for it is more the exception than the rule to-day to chronicle in our pages the construction of a new locomotive utilising saturated steam in its cylinders. In the feed water heating section similar attention is given to the progress of this important means of securing economy in locomotive operation. Details of early apparatus is illustrated and described, whilst many of the latest developments in Europe and America form the subject matter of careful enquiry and study

Pyrometers, Ezer Griffiths, London: Sir Isaac Pitman & Sons, Ltd.
Dealing with recent pyrometric appliances and methods of measuring temperature, rather than with the design of the instruments, this book should have a wide interest amongst engineers and scientific workers. It may be described as an intermediary between the text-books on heat on the one hand and the advanced treatises on pyro- metry on the other. Special mention is made of outfits designed to meet novel requirements as suggestions for solving problems that may arise in practical experience. Commencing with a short account of temperature scales, the succeeding sections describe expansion thermometers and their calibration, thermoelectric pyrometers, resistance thermometers, optical pyrometry-dealing with the dis- appearing filament type only-and total radiation pyrometers. Notes on electric furnaces are given in the concluding chapter. There are forty-nine illustrations, a good index and a useful bibliography of the subject.

The Railway Year Book, 1926. London: Railway Publishing Co. Ltd.
The re-organisation due to the grouping of the British Railways having been completed, as well as the amalgama- tion of the Irish lines, there are not so many changes in the new volume of this useful annual as in the last editions. An article on the Great Southern Rys. (Ireland) gives the statistical and historical information in a form that will cover the situation for some time ahead. New maps for the Southern, London Underground, Australian and Canadian Rys, are included. In the case of all railways dealt with, the particulars as to the staff, organisation, and general information, have been revised practically up to date, and everything has been done to make the book useful in railway offices and trading and manufacturing firms, as well as among general readers.

Recent accidents. 170.

Major Hall's report on the level crossing accident at Fenny Stratford, L.M. & S.R., on 7 December 1925, showed that the responsibility rested entirely on the driver of the road coach, who, together with eight of the passengers, lost his life as a result of crashing through the gates and being run into by the 18.30 passenger train from Cambridge to Bletchley, six other passengers being also injured. Major Hall finds that there was nothing amiss with the equipment of the road vehicle or in the arrangements at the level crossing, but suggests that the presence of a passenger on the driver's seat may have had some bearing on the tragic sequel. He attaches no blame whatever to any of the railway staff. The passenger train was drawn by engine No. 117—of the 2-4-0 type and weighing 60 tons 12 cwt., and consistfd of three eight-wheeled coaches and a six-wheeled van weighing 93 tons in all. The road motor coach was demolished and the crossing gates badly damaged, whilst the leading bogie of the second vehicle in the train was derailed and slight damage inflicted on the engine and other vehicles, but none of the company's servants or passengers sustained any injury.
The first accident of 1925 inquired into by the Ministry of Transport took place at Clevedon, G.W.R., on 23 January. The 13.02 motor train from Yatton on this date failed to stop at the proper place and came into collision with the stop blocks, causing injuries of a minor character to five passengers and more serious injuries to five others. The motor train consisted of steam motor coach No. 75 and.a trailer coach, both on eight wheels. The former had a length of 59 ft. 6 in. over mouldings and weighed 38 tons 16 cwt., of which 25 tons 4 cwt. was carried on the engine bogie and 13 tons 12 cwt. on the trailing bogie. The trailer car had a length of 70 ft. and a weight of 30 tons 13 cwt., equally distributed over the two bogies. The seating accommodation of the two cars was 45 and 70 respectively. Major Hall is of opinion that the mishap was due to the driver approaching the terminus at too high a speed and failing to apply his brake sufficiently early, and that he was misled as to his position by the singularly heavy rain which started as they passed the distant signal. The stop blocks were badly bent and broken and the station wall shaken, whilst the steam motor suffered broken buffer castings and beam and other minor damage.

[Development of the Locomotive, published by Central Steel Co.]. C.B. Chaney
Re Issue of April 1926, there is a review of the book Development of the Locomotive, published by the Central Steel Co., in which appear several adverse comments.
Though the writer has no authority to speak for the Central Steel Co., permit me to make the following reply. The subject matter of this book was originally prepared by laymen, not conversant with the details of locomotive history, who used cuts of early and important locomotives, adding thereto artistic embellishments to catch the eye, in a series of advertisements placed by the Steel Co. in the American technical press. The series was nearing completion when the Steel Co. decided to publish the series in the more substantial book form, and about this time the well-known locomotive historian, J. Snowden Bell, and the writer, were among those whose services were enlisted in an advisory capacity. Many of the cuts were already made and the artist, located upwards of 1,000 miles from New York, was not in a position to consult Bell or the writer as to the very minor details of surroundings of the subject of illustrations-the locomotive engine itself. These minor details were, of course, recognized, but the work was too far advanced to re-make many of the illustrations-hence the discrepancies mentioned in your criticism, such as the "Stourbridge Lion" shown without tender and in front of a building suggesting a depot at Baltimore-when, as a matter of fact, the "Lion" was tried on a line of road several hundred miles from the city mentioned.
The efforts of Mr. Bell and the writer were therefore confined to seeing that accurate representations of the engines themselves were made (in several instances where incorrect locomotives had originally been depicted, the cuts were discarded and new ones made) and that the descrip- tive data contained in the text was accurate. In these endeavours the results were quite successful, inasmuch as but one real error crept in-a very commonly made error, stating that Hinckley's "Lion" (page 30) was the first by that builder, whereas Hinckley built several engines before the "Lion" was constructed.
It was not the intention of Mr. Bell in his foreword to slight foreign practice or accomplishments, nor ignore the existence of the very fine British express engines, many of which made their records as built without truck or bogie. His statement concerning the necessity of a bogie applied solely to American practice-on the average road in this country, with its "banks" and curves, no exceedingly high speeds could be safely negotiated with a locomotive having no leading truck, and no competent railroad man would attempt such an experiment.
As to the engines shown without tenders. The original engine Atlantic did not have a tender when first operated; its supply of water was contained in a cask, and, with the coal supply, both were carried on the footplate of the engine. The Atlantic, now restored by the Baltimore and Ohio Railroad. still runs under its own steam at exhibi- tions, without tender, the coal and water being stowed as above. As to Campbell's engine, the first 4-4-0 (page 27), all that has ever been unearthed concerning this pioneer design is the outline drawing and patent specifications. The type of tender remains unknown. Referring to type designs, it is a fact that practically all of the designs of wheel arrangement of tender locomotives have been evolved in America, whilst of tank engines, the reverse seems true; nearly all tank designs being the product of our British cousins.
No comparison of the Steel Company's publication with Pangborn's "World's Railway" should be made. In the latter case, the compiler was a railway man, with a great railroad backing his efforts to make a complete and accurate history. That some of the illustrations and text of his book were erroneous was due only to the compiler himself in not being a mechanical man and not obtaining proper and competent authority to advise and correct the work. In the case of the Steel Company's book, the original aim was to get out a series of catchy advertisements calling attention to the products of the company. In this they succeeded admirably.
The resultant publication by the Central Steel Co. is without doubt superior in many respects to, and more nearly accurate than any similar brief treatise tracing the evolution of the locomotive through its early days abroad, thence through its American development of the last 96 years; and the little brochure is one of which its publishers, the Steel Co., as well as its makers, may well be proud.

Oil not too plentiful in Stores Department. Malcolm M. Niven
The essay on lubrication is very good; it is exhaustive in fact, but one thing I would ask locomotive men who pride themselves on designing engines and turn out magnificent work. Oil to-day is stinted on a great degree — drivers do not get enough oil to syphon their engines to save them from extensive cutting of journals and brasses, not to speak of valve and piston disturbances.
I heard of a recent case on a famous line where the trimming on a journal consisted of about two strands of worsted to feed a very important part. The company will not give out oil — oil hunters are on to gauge oil; some of these men were firemen at one time, but not technical men who could see that to stint oil is false economy. Oil inspectors should be technical men.
In 1897, when I was on a Scottish railway, the Scottish-English engines then were supplied with Gallipoli olive oil, and I believe S.W. Johnson, of the Midland, used olive oil on his famous Midland 4-4-0s all the period of his reign.
While olive oil in these times may be out of the question, the oil supplied might be greater in quantity, and the quality could be improved, there would then be less heating engines, and if your technical essays were acted on, life in the round- house and on the footplate would be less anxious than it is to-day.

Beckett, Laycock & Watkinson, Ltd.,  204
Acton Lane, N.W.10, have just issued a well illustrated catalogue comprising all their Beclawat specialities for railway rolling stock, ships and road vehicles. The publication has been very carefully designed, and should be of great interest and value to all railway officers and rolling stock builders, as it is probably the only one of its kind illus- trating actual modern fittings. The excellent reproductions of the numerous fittings and appliances manufactured by this firm are accompanied by good descriptive matter and prices. The section headings are :-Sliding door equipment with balanced frameless windows, steel jalousies for ships' windows; Frictionless ball race runners for sliding doors; Grid roof ventilators for ships; Locks and catches; Hat and coat hooks; Silent window channels; Corrugated dove- tail section steel flooring; Window tightening devices; Ash trays; Elastic axle journal packing; Spring clips for wagon labels; Window balances; Sliding windows for locomotive cabs; Vestibule gangways (Pullman type), and sliding ventilators for railway carriages.

Rokeby and Bouch feedwater heater which gave a water space of about 3 in. around the chimney proper. The products of combustion from the tubes and the exhaust steam from the blast pipe passing through the chimney heated the water in the chamber to a considerable degree. At the foot of the chamber a pipe passed the heated feed water to the left-hand pump and thence to the left-hand clackbox into the boiler. By closing the cocks "A" and "C" the heater could be put out of commission and cold water fed direct from the pumps into the boiler. The results obtained by the use of this device are said to have been of a very satisfactory nature, so much so that orders were given for six large mineral engines Nos. 145-150 of the Panther class, then under construction at R. & W. Hawthorn's works at Newcastle, to be fitted with an improved form of this feed heating apparatus. We regret that we are unable to give any data as to the economies effected by this appliance. Amongst the older school of enginemen the device was somewhat irreverently nick-named " Bouch's Coffee Can."

Operation of steam locomotives during an emergency. No. III. 257
Clean  tubes are essential if free steaming is to be secured with a locomotive boiler. Once the tubes become partially choked with soot it is hopeless to expect good results, no matter what attempts are made with the firing, the gases are impeded in their passage to the smokebox, the conduction of heat to the water is impaired and indifferent combustion of the fuel on the firegrate imposed. The orthodox method of cleaning tubes on British locomotives is, as is well known, by means of a piece of waste or strand of spun yarn attached to a long thin rod which is pushed down each tube from the open smoke box end. The operation is a dirty one at all times, but when performed with the boiler under steam despite the fact that the blower may be kept on "full" during the time, the worker is sure to get full benefit from the stray soot blown about.
In answer to the query, Can this be obviated? we are inclined to say it can, provided the direction of cleaning is reversed, that is, the work undertaken from the firebox instead of the smokebox end. In America it has been the practice for many years past to permanently fasten up the smokebox or front end, as it is called, and clean all tubes, etc., from the firebox.
Many attempts have been made to meet the British conditions but apparently the readiness of the staff to do such low-grade work (it would not be tolerated in some more advanced countries) has prevented appliances being adopted. The most successful arrangements rely on a steam jet or jets introduced through suitable openings in the firebox being so manipulated, either automatically or by hand, that they will successively clean all the tubes of the tubeplate, blowing the soot through into the smokebox. Such appliances can be used during the run and can be put into operation at any time foulness of the tubes is anticipated, although it would appear desirable to select the locality for the operation, or complaints from the public who happen to be adjacent to railway property are to be expected.
A rough and ready means of cleaning tubes often adopted with oil burners is to first introduce a few pieces of wood into the fire, presumably to make sparks, and tend to ignite the soot, then drop the engine into full gear and throw into the firebox a bucket or two of clean, sharp sand-what passes the brick arch goes through the tubes like a sand blast- and a cloud of smoke, soot and dirt is usually thrown into the air from the chimney. Where labour is expensive and difficult to obtain, locomotives are running fitted not only with tube cleaning appliances but with self dumping arrange- ments for cleaning the smokebox.
Lubrication of the locomotive, although now almost entirely controlled from the footplate or cab, is still an interesting detail to study if more facile operation is to be secured. The lubrication of a motor car can be manipulated by its lady driver without moving from her seat, and there is no reason why the requirements of a locomotive cannot be similarly arranged for. The use of grease for all the motion parts, axleboxes, etc., of the large locomotives in the U.s.A. has contributed largely to their easy working and automatic lubrication, its benefits are loudly proclaimed by those who use it and are so satisfied with it. Grease must be more easy to apply and manage and, further, it must require far less attention than oil. We believe axleboxes of rolling stock have been sealed up for periods of six months with suitable grease as the lubricating medium, requiring no attention or renewal. How often do the main axle bearings of motor cars require inspection? Doubtless the ball bearings used have their influence on this, but it certainly seems as if there is room for advancement in providing our steam locomotives with more facile means of automatic lubrication and so reduce the necessity for so much manual attention.

New Zealand. 257
The announcements that have been made from time to time of the extensive railway workshop undertakings in New Zealand, have excited very considerable interest amongst British manufacturers. A number of contracts have already been let in this country, and it is hoped by the New Zealand Government that virtually the whole of the necessary material will be obtained here. Four workshops, fare included in the scheme, and at present tenders are being invited by the High Commissioner for New Zealand for a new carriage and wagon works at Otahuhu, Auckland. Plans and specifications are on exhibition at the Chambers of Commerce at Glasgow, Manchester, and Birmingham, at the Offices of the British Engineers' Association, the Board of Trade, London, and the Offices of the High Commissioner for New Zealand, 415, Strand, London, W.C.2. A sum of about one-and-a-half million sterling is involved in the general scheme. Tenders are similarly being invited for re-modelling undertakings at the workshops at Addington (Christchurch). and Hillside (Dunedin).

Their original numbers were 473, 475 and 514, but were renumbered 1473, 1475 and 1514 in 1902, and in 1919 had an A fixed behind their numbers in consequence of other engines arriving bearing the same numbers. They have recently been renumbered again, and are now running with Nos. 1458, 1459 and 1460 respectively. These engines will probably be replaced in the near future, and with them will go for ever one of the connecting links with the infancy of the East Indian Ry.
We regret to learn from India that the writer of the above article, H.T. Kerbey, in charge of the locomotive depot at Moharneh Jn., East Indian Ry., passed away on June 13 as the result of a heat stroke. Kerbey was formerly a driver on the Great Eastern Ry, at Stratford, and took part in the trials of Holden's Decapod.

Automatic mechanical couplers in India. 267
Advocacy for adoption of the M.C.B. type of coupler in preference to any newer device has been largely dependent on being the accepted standard of America and is in general service on a most extensive scale there. I aturally, when such an adoption is quoted, it has its effect on those held responsible for an adjudication on the selection of a coupler for India.
It appears' to us, however, that the value of such a recommendation may be considerably discounted when it is known that the alternative coupler is the outcome of years of experience with the M.C.B., and its design has been undertaken by the same experts who are largely responsible for the most approved development of the latter.
The report of the Coupler Committee of the A.RA. at the recent Convention held at Atlantic City, substantiates our view that the standard D coupler cannot be accepted as a perfect coupling device devoid of all troubles. Of a total of 1,534 standard D couplers with small (5 in. x 7 in.) shanks removed from service during six months on the eight railways represented on the Committee, 466 were condemned for failures in the head and 1,106 from defects in the shank, whilst of 906 couplers having large (6 in. X 8 in.) shanks removed during the same period, 805 suffered in the head and only 141 in the shank, showing that the increased strength in the shank throws more strain on the head and this consequently suffers more.
For the 1,271 couplers which failed in the head a total of 1,453 detailed defects were recorded, made up as follows: Guard arm or outer wing 247 approx. 17% Face of coupler 696 48% Side of cavity for knuckle tail. 370 25% All other defects 140 10% Experience in this country, too, with the M.C.B. coupler confirms the impression an improved device is worth trying.
The Willison is a vertical plane coupler, functioning in very similar manner to the M.C.B. but devoid of a revolving knuckle, able to operate with far less slack and so arranged that all strains are equally distributed on both sides. Claims can therefore be urged that it possesses advantages over the M.C.B. as a mechanical coupler. Further, and of immense importance to India, it possesses means for transition whereby inter-coupling with the ordinary stock is assured without any rearrangement, addition of parts, etc. This is amply confirmed by the large number of vehicles fitted and in regular service.
By the kindness of a corresponden t on the spot, we are enabled to illustrate a recent application to the carriages forming the Madras- Bangalore mail train of the M.S.M. Ry. Other trains equipped with Willison couplers are the Lahore-Kalka express of the N.W.R, a passenger train of the B.N.R, and finally, the Bombay-Poona mail train of the G.I.P.R. This last we may say was the first train in India to be fitted with automatic mechanical couplers of the M.C.B. type, and these have now been replaced with Willison couplers.

:Electric lighting of trains and stations—Indian State Railways. 271
The cars of the Calcutta-Darjeeling mail train of the Eastern Bengal Railway have been equipped with external electric lights, so arranged that when the train stops at a station the lamps automatically light up and illuminate the platforms; they continue alight until the train has started and reaches a speed of 8 miles per hour. A similar arrangement is in use on the Postal trains in this country and was proposed on the G.I.P.R. some years ago for suburban trains to improve matters at the smaller and badly lighted stations between Bombay and Kalyan. As, however, only a portion of the trains employed had electric light, and with the electrification then proposed, power would be available throughout, the scheme was dropped.
A disadvantage of this temporary illumination of the platforms is that often (in the intense dark night of India) when the "train has left, the whole of the station offices, buildings, etc., are plunged into what appears to be a deeper gloom, pro tem, than that which prevailed prior to the arrival of the train, and this affords the opportunity for thieves, etc., prowling about the premises.
The satisfactory and economical lighting of railway stations in India is a live problem and offers a most promising field for manufacturers of such arrangements.
In our opinion an automatic electric installation similar to those used for country houses and good for 30 to 50 lights, would meet the case, provided a well organised -.System of supervision, stock of duplicate parts and spares for repair was installed at the same time. Independent and isolated equipments have no friends and soon become un- reliable and unworkable.
A whole section or division should have its stations equipped with one make of apparatus and regular inspection instituted. If the plant included a water pump for station needs it would, in many cases, be acceptable, and there is no reason why at locomotive watering stations the plant should not include the pumping for the water tanks: it would all tend to economical working.

New South Wales Government Rys. 271
The Railway Department is disposing of eleven 2-8-0 goods engines, class Z 29 (late J class). These engines, which had been more or less idle for some time, were imported in 1891 from the Baldwin Loco. Works, and were typically American with bar frames and other features and had cylinders 21 in. by 26 in. and 4 ft. 3 in. diameter driving wheels. They were in their day the most powerful engines on the system, and lately six of them were rebuilt and superheated, the cylinders being increased 1 in. in diameter and the pressure reduced to 140 lb.
It is many years since a serious accident happened to a mail train in N.S.W., but on the 10 June, just after the Brisbane Limited had passed through Aberdeen, a small village 187 miles north of Sydney, and was approaching a viaduct that connects with the steel bridge over the Hunter River, a wheel of either an engine or tender or coach left the rails while the train was travelling fast, the result being the collapse of the viaduct and the precipitating of the train engine, brake van "and five coaches on to the river fiats below. The drawbar connecting the two engines snapped leaving the leading engine on the track, though its tender was partially derailed. The three last coaches also kept the rails. Fortunately the coaches were of the latest modern type and withstood the severe strain remarkably well, though the second coach was split in two, one of the ends being smashed to pieces. Four passengers were killed, and thirty-nine injured including the fireman of second engine, the driver being unhurt. The sufferings of the injured were rendered more acute by the cold night and the remoteness of the locality. The train engine, which lay half buried in the earth, was No. 3504, NN type cylinders 22½' in. by 26 in., 5 ft. 9 in. drivers, 170 lb. pressure (recently illustrated in the LOCOMOTIVE magazine), while the pilot engine was a 4-4-0 express, 18 in. by 26 in. cylinders, 6 ft. 0½ in. drivers, 3 ft. 6 in. bogie wheels, 140 lb. pressure and weighing 65 tons. The cause of the derailment was difficult to locate as everything was apparently in first-class condition.

Retirement of Inspector Flewellen, G.W.R. 271. illustration (portrait)
Chief Locomotive Inspector George Henry Flewellen, a well-known official in the railway world, had retired from the service of the Great Western Ry. Born at Wiveliscombe in August 1861, he joined the G.W.R. at Bristol in June, 1878. Starting as a cleaner and fireman at Bristol and Birmingham, he went to Taunton as a driver and was afterwards transferred to Plymouth. In June, 1901, he was appointed District Inspector for the Newton Abbot Division, and in February, 1908, he went to the head office at Swindon. He has received diamond tie pins from H.M. King George and H.R.H. King Albert of the Belgians. The late Maharajah of Cooch Behar, India, presented him with a silver cigarette case. He has had charge of many notable trains including about 100 Royal specials, Princess Marys honeymoon special, the Prince of Wales' special from Plymouth on his return from India, June 21st, 1922. On May 19th, 1904, he ran an ocean mail special train from Plymouth to Paddington in record time on the City of Truro when a speed of 102·3 M.P.H. down Wellington Bank was attained. He took an active part in the trials between the L.N.W.R. and L.N.E.R. tests against G.W.R. engines. He was in charge of the engine Windsor Castle when H.M. the King drove it from Swindon Works to the Station in 1924. In July, 1925, he was made a Member of the British Empire in connection with the Centenary of British Railways. He retired on 4 August having spent 48 years in the Company's service.

Through the window, No. 3. Paddington to Killarney, via Fishguard and' Rosslare.
London: G.W. Ry. Co. Office of the Superintendent of the Line. Uniform with Paddington to Penzance and Paddington to Birkenhead , this book of 135 pages describes in detail the points of interest seen through the carriage window on the journey of 415¾ miles from Paddington to Killarney, and the 54 miles by G.W.R. steamer from Fishguard to Rosslare, across St. George's Channel. Each page of the letterpress covers about six miles of the line, faced by a map of the same section on which points of interest are identified by reference numbers corresponding with those used in the text. Passengers who make the journey from Paddington to Killarney represent only a portion of the much larger number who will travel this route by shorter stages, and the book therefore serves a much wider purpose than that of reaching a single destination in the south-west of Ireland. Incidentally the glimpse afforded of the works at Swindon and the experience of passing through the Severn Tunnel, are suggestive of the engineering achievements of the G.W. Railway.

Correspondence 272

Reversing gears. Malcolm M. Niven..
Re technical essay on Footplate arrangements, the reversing gear comes in for analysis, and I would like to point out that James Stirling's reversing gear of 1875 applied to the Glasgow & South Western Ry. 240 class 0-4-2 engines by Neilson & Co. of that date, was a very efficient gear and capable of adjustment equal to the balance wheel hair-spring of a chronometer. I need not describe it, better experts than I know it very well; it is still used on all the engines attributed to Mr. Hugh Smellie, both goods and passenger, and was adopted by Manson on every engine he built. Prior to 1875 Stirling's screw gear was used, from about 1873, a horizontal wheel, vertical column and, of course, a trunnion block and screw to a bell-crank below the footplate. A brass plate indicated "Fore" or " Back" gear positions and the percentage of cut-off. No lever and sector was fitted to any G. & S.W. locomotive after the 2-4-0 No. 8 class, and I can say that there never was a "surge" throughout the train when a driver notched up either with the screw or Stirling steam gear.
After a driver had had an engine for perhaps some months on the work allotted to him, he took a file and put a little mark at the running position where the engine worked best, and in the dark he could feel the place with his forefinger on the plate. The screw gear was used on the Caledonian 4-4-0 engines of the 83 to 90 class of Drummond, and an exactly similar gear was employed by Matthew Holmes on the 4-4-0 classes he turned out for the Waverley route to Carlisle; however, these engines now have a lever and sector after rebuilding, about 1922.
The Caledonian-Oban 4-4-0 bogies of Brittain, i.e., the 181 class now 1181, etc. (or, of course, 14,000 odd in L.M.S.) had direct Stirling steam gear, the only ones fitted on this railway.
The screw seems to be coming in again, as I see that the Stirling gear is not being perpetuated any longer on the L.M.S. engines, in fact the 15,260 series of suburban engines have the Caledonian lever as used in Drummond's old Cathcart engines of the 'eighties.

Stablex. 272
A treatise on the structure and uses of stabilized bitumen has been published by D. Anderson & Son, Ltd., of 63, Fenchurch Street, London, E.C.3. This patented protective coating- Stablex-has the following qualities. By the addition of a protective colloid the latent gases of ordinary bitumen are dispersed; its structure be- comes consolidated, and a higher degree of ductility is attained. This means greater durability, computed to give at least double the life of ordinary bitumen. It is also acid-resisting and as it is claimed that a full coat of Stablex is equal to three coats of paint it should be of value for coating the roofs of railway vehicles, and for the protection of metal work in engine sheds, bridges, viaducts, etc. .

Steels for general purposes. 272
Sir W. G. Armstrong, Whitworth & Co., issued a book printed in excellent style with well chosen illustrations very clearly reproduced. It contains a number of technical articles, which deal with modern views on steel and its properties and especially with the value of mechanical testing to engineers. Data on results of the various tests together with information on the inspection of ingots and forgings for internal defects will acquaint engineers with the characteristics of the steels manufactured at the Armstrong plants. The properties of the new Vibrac steel, claimed to be the super steel of the age, and its softening for machining by heat treatment, are dealt with in detail, as well as other steel products made by the firm. The book is substantially bound in imitation leather.

Fabrikoid seat covering for railway carriages, etc. 272
The Welin-Higgins Co., Ltd., of Morley House, 314-322, Regent Street, W.1\., booklet, with cover Fabrikoid leather cloth, and describing the uses and advantages of this material as a seat covering for railway carriages and public conveyances. A closely woven cloth base of great tensile strength, is coated with no less than twenty-seven applications of Pyroxylin, one of the toughest wear-resisting substances known. This Pyroxylin, in ad- dition to its long wearing properties, is pliable, sunproof, heatproof and waterproof, and is impervious to grease, dust or dirt. It can be washed easily with soap and water and without any fear of becoming threadbare or shabby. Fabrikoid can be supplied to match any colour desired. Insects and vermin will not attack it; mould and mildew will not harm it. In spite of these advantages, this material costs no more than inferior artificial leather and less than leather itself. The sample sent us appears to fulfil all the claims made by the manufacturers.

Argues that primitive torch oil lamps used in Britain should be replaced by electric lighting supplied by a turbo gennerator as used in America: in Canada on oil burning locomotives the exhaust is illuminated to show whether the controls are set correctly. Filling the water tank is greatly asssisted if the location of the filler cap on tenders and tanks is standardised. In Austria filling is greatly assisted by the ability of the water crane to extend to the locomotive. In Britain time is wasted positioning the locomotive.

Metal fittings for restaurant cars. 305
The attractive alloy known as Monel metal has recently been introduced for the cooking utensils and other fittings of the kitchens of restaurant cars. It consists approximately of 67 per cent. nickel, 28 per cent. copper and 5 per cent. other metals, made directly from the ores; it contains no tin, zinc or antimony. In appearance it is very similar to pure nickel, but possesses a more silvery lustre. Monel metal can be rolled, drawn, cast, forged or welded and is consequently applicable to numerous uses where a strong and non-corrodable alloy is required. At a temperature of 750°F. a forged rod of this metal has seven times the strength of a similar one of brass or bronze. Messrs. G. & J. Weir, Ltd., of Cathcart, Glasgow, are responsible for its introduction in this country.

New South Wales Government Rys. 305
Though scheme after scheme has been discussed for the last thirty or more years the first practical step towards the unification of Australian railway gauges has been taken by the New South Wales and Queensland Governments, assisted by the Commonwealth Government, in commencing the building of the Kyogle- Brisbane Ry, to the standard (N.S.W.) gauge. Kyogle is on a spur line off the main North Coast Ry. and 27 miles from the border. From the point where the railway enters Queensland territory to Brisbane is 70 miles, and the line is being con- structed through country not served by present railways. When completed the distance between the two cities, Sydney and Brisbane, will be shortened by roughly 117 miles. This North Coast line is at present connected by a train ferry at Grafton with the rest of the State system, and under the agreement, N.S.W. has to bridge this gap over the Clarence river. A double deck bridge is proposed, and it will also be necessary to strengthen the track from Grafton to Kyogle, 83 miles, to carry heavy main line traffic.
At the enquiry into the Aberdeen smash which occurred on 10 June, it was found to have been caused by the heavy rains weakening the embankment, the deflection causing a wheel of one of the vehicles to leave the track 200 feet before entering on to the viaduct. The application by the driver of the brake seems to have caused the wheel to cut into the viaduct causing the collapse of the structure.
Excavation for the Town Hall Station of the City Ry. section has just been commenced.
The introduction by statute of the forty-four hour week has cost the railways £51,387 in additional expenditure, according to figures published by the department for the quarter ending March 31st. The extra expenditure on the State Tramways was £33,279 for the same period. In connection with the Sydney Suburban Railways Exten- sion, The Westinghouse Brake & Saxby Signal Co., Ltd., have received an order from the Metropolitan Vickers Electrical Co. Ltd .. for 101 Motor Driven Air Compressors, Type DH.

An unusual mishap. 305
On Saturday, 6 February 1864, a locomotive belonging to the North British Ry., which had been repaired at the North Eastern Ry. shops, at Newcastle (Central section), had its coke fire lighted to raise steam preparatory to being sent back into Scotland. As the morning was stormy, the shed doors were shut; the fire in the locomotive raised steam too fast, and a damper was put on the chimney, with the result that the fumes and noxious gasesl from.the coke fire, having no egress, filled the shed. The men at work appeared oblivious of the state of affairs, until the fumes affected one of them sufficiently to cause him to feel sick and giddy. On reaching the open air he fell, four others became insensible, one was considered dead for a time; in all six men suffered severely.

Reviews. 306

Diesel engines—marine, locomotive, and stationary, D.L. Jones, New York: The Norman W. Henley Publishing Co. London: The Locomotive Publishing Co., Ltd.
Without going deeply into thermo-dynamics, the writer presents' a practical manual for the operating engineer, giving the principles, care and operation of the Diesel oil engine, as well as information likely to be useful in everyday work. It should also be interesting to the advanced engineer and designer. No engine is more susceptible to bad attention and handling than the Diesel. There are a number of somewhat intricate units in the machinery, each of which is vital to the working of the whole plant, and anyone of these, if allowed to operate at less than a fair percentage of full efficiency, can cause consider- able trouble. It is only fair to say that the necessary adjust- ments of these parts are as readily remedied as they are liable to require attention, provided the engineers are as well trained in expert observance as they are versed in the means of making correct adjustments and repairs. To obtain best results a thorough understanding of the principles of operation of the engine is essential; afterwards constant attention to every detail on the part of the engineer in charge.
Although the main portion of the 558 pages is devoted to the construction, operation and maintenance of the Diesel engine for marine and power house work, a lengthy chapter describes the latest developments in Diesel locomotives in America. The book is particularly well printed and contains 241 illustrations, principally very clear line drawings.

The locomotive in service—driving, light repairs, management; London: The Locomotive Publishing Co., Ltd.
Written by practical men for the guidance of all engaged in the work of running locomotives, this book should also prove a valuable manual to those who need information in preparing for higher positions in railway locomotive departments. The 187 pages are divided into 31 chapters, copiously illustrated by means of 87 illustrations with a large folded sectional chart of a 4-6-0 express locomotive and tender for the Great Indian Penin- sula Ry., clearly figured to correspond with a table of the vario~s details. There are very few half-tone illustrations but this is not to be wondered at in a practical work. Among the subjects to be dealt with are locomotive driving and firing, the care of boilers, bad steaming engines, and engine failures and remedies, while consideration is also given to protecting boiler plates, fire grates, brick arches, superheating, lubrication, brake rigging, connecting rod big-ends, etc. Information is also given on such important matters as testing valves and pistons in steam, re-metalling and fitting eccentric strap liners, re-grinding steam cocks, wheeldrops for runnmg sheds, and all important subjects connected with locomotive running, shed management, breakdown work and repair organisation, while smaller details have also received attention.

[Three-cylinder locomotives]. E. Joslin.
Hceckers letter is very interesting, but makes no mention of the fact that the Southern Pacific and the Union Pacific have between them some forty engines of the 4-10-2 type, all three cylindered. Granted, the outside cylinders have 32 in. stroke, while the inside one has only 28 m., but the engines must be satisfactory or they would not have so many in service. Hcecker has also overlooked the fact that the Southern Ry. cannot run much more than 20½ in. cylinders (outside) over the S.E. section, so multi-cylinders must be used. Again the work of the two 4-6-2 types (L.N.E.R.) seems to be equal; they have both done their 80 rn.p.h., both have worked 530 tons out of King's Cross, and kept time.
The Gresley gear used may have refinements that, the German and American gears lack. Again, the new 4-8-2 s for the Central may be limited cut-off, which, I believe, has great advantages for a freight engine with two large cylinders, but loading gauge restrictions prevent their use m England. . I was very interested in the Spanish 4-8-2 m the Apnl number, but would like to ask His Grace of Saragossa, If a two-cylinder or three-cylinder simple, with booster would not be as effective, and cheaper? The new 4-8-2li of the S.A.R. I have in view, but, of course, smaller, say with 23 in.:x 28 in cylinders, 200 lb. steam and 66 in. wheels, and 10,000 lb. or so in the booster. European designers appear to hesitate in adopting this very useful device. I hope it will come into more general use.
Just about the time you published the Apnl number the rainfall occurred at Broken HIll, and put about 20 feet in one day into the reservoirs, so that the extra rolling stock was unnecessary. No tears were shed, needless to say. The line from Port Augusta to Redhill wIll be under construction very soon, and we shall then have the 5 ft .3 m. and the 4 ft. 8½ in. gauge from here to Adelaide. They intend to lay the 4 ft. 8½ in. gauge inside the 5 ft. 3 m. on the third rail system and to broaden the gauge from Brinkworth to Gladstone.

The Institution of Locomotive Engineers. 316
See J. Instn Loco. Engrs., 1926, 16, 743. A very full attendance marked the inaugural meeting of the winter session held on Thursday evening, 30 September, at the Engineers' Club, Coventry Street, W.l. The President was supported by R W. Reid, C.B.E., the retiring chief officer; H. Kelway- Bamber, H.N. Gresley and J.C. Sykes (secretary of the Institution). The retiring President, R. W. Reid, (L.M. & S. Ry.), after reading letters of apology from Sir Henry Fowler, ((L.M. & S. Ry), and A.C. Stamer. (L. & N.E. Ry'.), welcomed the new President, Sir Seyrnour B. Tritton, on behalf of the Institution, and stated that he was sure that an engineer of his standing in the profession would give impetus to the work of the Institution. Although the Institution of Locomotive Engineers was not so old as some others, it formed an important part in the Information Bureau of Locomotive Engineers, and from the expressions of opinion he had received, not only from British but foreign and colonial railwavs, he was sure that it was much valued.
Sir Seymour then gave his address. After commenting on the wonderful work done bv the pioneer locomotive builders with most elernentarv and crude material, Sir Seyrnour gave a word of advice to those intending to follow the profession of locomotive engineering. He particularlv emphasised the necessity for students to follow carefully the best methods of manufacture and also the behaviour of details and material under test. He expressed his disappointment at so many of the candidates for India and colonial appointments, who had passed high qualifying examinations, being unable to describe intelligently how such a thing as a locomotivc tyre was manufactured.
He also touched upon the question of heat treatment. showing the great importance which it held in the manufacture of modern steel, and how want of, or improper, heat treatment, might be the cause of failure of the very best steel being used, and even become dangerous. He illustrated this point by alluding to the method of manufacture of screw couplings, amongst other parts, and suggested that a Paper on the properties of materials and their relation to locomotive design would be of interest. Sir Seymour expressed the opinion that the British railways might profitably utilise some of the time spent by apprentices in the mechanical department, for inspection and test work, so that they might be better qualified for responsible positions on colonial and foreign railwavs.
Without making any historical retrospect, the President said it was somewhat difficult to bring forward a subject of fresh interest in connection with locomotive and carriage and wagon work. It is often said that the steam locomotive has reached its zenith, that it will before long be replaced most probably by the electric locomotive, and engineers should concentrate their energies on the latter. In countries where water power is abundant (such as Switzerland) and coal and oil are dear, there is little doubt that the steam locomotive will gradually die a natural death. During a recent visit to Switzerland, as one who had all his life been connected with the steam locomotive, he was rather startled to see a large and central railway station without any signs of any steam propulsion whatever, whilst the "Orient" express by which he was ahout to travel towards England, came in to the minute, hauled by a magnificent electric locomotive. These are signs of the times. But in spite of coal and other troubles it would appear in this country the steam-propelled locomotive will be used for long distance express and goods traffic for many years to come, and it would be interesting to enquire what arc the chief causes which stand in the way of its still further development.
A very important subject next engaged Sir Seymour's attention, namely the loading gauge of railways, and some verv interesting notes were given on the different composite gauges now being worked to in Great Britain and on the American continent, with some comparisons made with the new outline adopted for the 5 ft. 6 in. gauge in Injdia. The loading gauge restriction, although a serious drawback to the development of larger and more powerful locomotives, has perhaps brought out certain developments, because the designer, being unable to get the cylinders of his locomotive within the space required, has been driven to turn his attention more closelv to three and four-cylinder engines. Although, no doubt, the permissible axle load has been the principal factor in the development of the articulated engines, such as the Garratt, the Mallet and other tvpes, the restriction of the loading gauge has no doubt also affected the development of their design.
When called upon for advice for new rolling stock for the metre gauge railways in Iraq, Sir Seymour, in discussing the matter with the General in authority, asked as to the limits of the loading gauge prevailing, and was informed that it was represented by "the sky above and all round you." A very satisfactory condition.
Referring to the efforts made by the Ministry of Transport to secure some improvement in the British load limits to permit of more liberal interchange of rolling stock with the Continent, Sir Seymour said it was found that the improvements required on the single route from Dover to London would incur expense of such magnitude that it could not be proceeded with.
For war service on the continent vehicles built to the French dimensions were adopted, as the capacity of the wagons was increased by 10 per cent. over tbe British. As some 3,400 locomotives and 73,796 wagons were built, the question of dimensions was of importance. Apart from the limitations of load gauge the progress of the steam locomotive in this country appeared to be somewhat handicapped by the type of boiler used. Much higher pressures. were being experimented with in Germany and elsewhere. He pointed out that developments were now being pressed forward for steam locomotives, in the form of Poppet valves and much higher pressures, and that the Diesel engine had passed the experimental stage, and the combined steam and internal-combustion engine on the "Still" system was being developed, and that new methods of transmitting the power generated in the engine to the road wheels were engaging the attention of the engineers of to-day. He asked that members who had studied these subjects from various points of view would contribute papers to the Institution upon them.
At the conclusion of the address, a vote of thanks was proposed by C.N. Goodall (R. Stephenson & Co.), who congratulated the new President in thinking out a new line in his address, adding his testimony to the value of the Insitituton. This was seconded by Major S. E. Williams, (Crown Agents for the Colonies) who stated that the success of the Institution has been greatly due to the zeal and ability of its Presidents. He had known Sir Seymour Tritton for many years and had co-operated with him in railway matters concerned with the Crown Colonies, and his advice had inevitably led to success.
H. N. Gresley, (L. & N.E. Ry.) touched upon several points in the address, confirming the great value he had derived when a pupil by a term in the testing and inspection department where he learnt not only about the strength of materials but methods of-manufacture and stating that, following on a suggestion by Sir Seymour Tritton, his pupils were given the opportunity of going through those departments. Gresley also alluded to the loading gauge, pointing out the British loading gauges took into account the lengths of the vehicles and the "throw over" on a curve, and fixed structures are set back to allow for this, but in the Continental loading gauge this was not so and great care had to be taken on this account. He was a member of the comrnittee which had to consider a possible increase in the loading gauge on British railways, when the "Berne" gauge was considered, and he confirmed Sir Seymour's note that the cost proved prohibitive. He concluded by saying that he was glad to note that the President was of opinion that the steam locomotive was not yet dead as regards this country, and although experiments were being made in much higher pressures, in his opinion this alone would not affect economy unless special consideration was given to improved steam distribution

Arthur and Louisa were "fearsome looking engines" with outside cylinders buil;t by Fossick & Hackworth in 1858 and 1860. They had 4ft 9in wheels. They became GWR Nos 903 and 904, A similar engine Victor was photographed at Swindon: it had come there via the Carmarthen & Cardigan Railway (it had been sold by the Llanelly Railway in about 1883. In 1865-6 the Llanelly Railway placed four inside cylinder 0-6-0 locomotives into traffic. Two were built by the Llanelly Railway and may have been designed by the locomotive superintendent. They were Alexandra and Wales built in 1865: they became GWR Nos. 907 and 908. Ernest and Edinburgh were built by Fossick & Hackworth in 1866 and were similar to Beyer Peacock products: they became GWR Nos. 905 and 906. The next engines were actual Beyer Peacock products WN 828/1868 Dunvant (GWR No. 913) and WN 829/1868 Towy (GWR No. 914). Four marginally larger Beyer Peacock products WN 889-92 were supplied in 1870: they became GWR Nos. 911-12 and 909: they had carried the names Grongar, Stradey, Teilo and Royal.

Correspondence. 335

Messrs. Stirling and Stroudley. Malcolm M. Niven.
Re account of Inspector  Aylwin's experiences there is no allusion to the Grosvenor, No. 151, 2·2-2, which was sent to the Railway Jubilee celebrations, 1875. In his account of the 0-4-2 engine Edward Blounit; at Paris, mention is made of the James Stirling 4-4-0 being temporarily converted into a 4-2-2. .I think that was perhaps the reason that she may not have given a good account of herself. I do not think the 7-ft. Stirlings could be depended on uncoupled: even as coupled engines they were inrlined to slip on greasy metals at the start.
When Grosvenor went to Darlington in 1875 a Glasgow and South Western engine was sent there also: it was one of the famous 7 ft. 1½ in. class, No. 106 of the No. 6 series. So that Stroudley and Stirling seemed in those days to be it in locomotive design.
It is interesting to relate that No. 6, the first Stirling bogie, ran for a time with a pair of her bogie wheels removed. I was speaking to a gentleman who can be relied upon. that this was the case, and it may have been sometime in 1873 when she came out. The rear wheels of the bogie were removed and the bogie frame suitably supported so that she ran as a 2-4-0 engine.
It must be remembered that Stirling developed the No. 6 class from the 6 ft. 7½ in. No. 8 class of 1868 or 1870. which were 2-4-0 engines.
There was a class with 6 ft. 1½ in. wheels built for the Greenock section, known as the 59 series. I think one is still in existence; if not, only recently removed ; she had her original perforated splashers and motion of the Stirling swing link pattern. No. 71a was her old (G. & S.W. number, built in 1870. This class came out simultaneouslv with Patrick Stirling's No. 1 8-ft. singles on the G.N. Now that all these Stirlings are disappearing I think the LM.S. ought to preserve one Stirling bogie, the precursor of the dorneless Stirlings of the S.E. Railway.

Early locomotives Dublin and Kingstown Ry. 336-7. 2 diagrams (side elevations)
Original locomotives supplied in 1834: three from Sharp, Roberts & Co. named Britannia, Hibernia and Manchester and three from George Forrester: Dublin, Kingstown and Vauxhall. The Sharp engines had vertical cylinders and drove via a bell crank motion. The Forrester locomotives were the first to have horizontal motion. These 2-2-0 had 5ft driving wheels. Two further Forrester locomotves were obtained in 1836 named Victoria and Comet: these were similar to the other Forrester products, but conveyed the coke and water on the locomotive. The other Forrester products were similarly modified, but the Sharp engines retained their tenders. In 1839 two locomotives were constructed at the company's own workshops in Serpentine Avenue, Ballsbridge, Dublin and were the first locomotives to be constructed by a railway company in the British Isles. These were Star and Jupiter and had 5ft 3in coupled wheels and 11 x 18in cylinders and had a 2-2-2T arrangement. Three further engines followed:  Princess, Shamrock and Erin. Both Hibernia and Princess are illustrated: the latter based on the original drawing sent us some time back by the courtesy of George H. Wild, locomotive superintendent of the former Dublin and South Eastern Railway. The wheels of the Princess were of cast iron with spokes of I section, and were made at the Dublin works. The valves were driven by a rocking shaft, with gab motion. The boiler carried a working pressure of 90 psi. The cylinders were 11 in. diameter by 16 in. stroke and the driving wheels 5 ft. 6 in. diameter. The front carrying wheels were 4 ft. diameter and the rear 3 ft. diameter; the wheelbase was 6 ft. 1 in. leading to driving and 4 ft. 11½ in. driving to trailing. It is said the original iron fireboxes of these engines were welded up, that is, the front and back plates, crown and sides at the joints. Other engines built at Ballsbridge of the same type, and soon after the Princess, were named as follows: Bellisle, Albert, Burgoyne, Cyclops and Vulcan. At this period the Dublin and Kingstown was 4 ft. 8½ in. gauge, but the gauge was converted to 5 ft. 3 in. in 1854-5, when the line was leased to the Dublin, Wicklow and Wexford Ry. The alteration of the engines entailed three new straight, longer axles, and lengthening the frame stays only.

New South Wales Government Rys. 337
The bridge across the Clarence River in connection with the new main line between Sydney and Brisbane is to be of the double decked type and built jointly by the Railway Department and the Public Works Department, the upper deck forming a roadway 22 ft. 6 in. wide and 27 ft. above rail level, which is 33 ft.above high water, though floods may reduce this level to about 5 ft. at times.

"The Model Engineer" Exhibition. 337
An exhibition of model engines, boats, etc., was held at the Horticultural Hall, Westminster, from the 18 to 25 September. There was a fine display of exhibits and a great attraction was the Wireless control of trains by Major Raymond Phillips, the inventor. Demonstrations were given and were well attended. One very fine 1½in. scale model was that of L. & S.W.R. 4-6-0 express engine, No. 486. It is stated that this model took 30,000 hours to build and the material cost £200. It is now worth £2,000, and is to be on view at the Science Museum, South Kensington. Another exhibit worthy of mention was an engine named Stanley Baldwin, built by Bassett Lowke, Ltd.,, for H.F.R. Franklin's Garden Railway, at Radwell, Bedfordshire. This is to run on a 10¼ in. gauge track and weighed about one ton. On the working model track J.C. Crebbin gave exhibitions in 'steam of his four-cylinder compound model locomotives, Aldington (4-6-2) and Sir Felix Pole (4-8-0). An excellent 4-4-2 type L.M.S.R. (Tilbury Section) tank engine model was also in steam.

Several of the new Crewe-built 0-6-0s (series 4302-11) had been put into traffic unpainted, including Nos. 4308 and 4310. The first ten of a new series of 25 similar engines had been delivered to Crewe by the North British Loco. Co. bearing Nos. 4382-91 (ex Queen's Park Works). All the new 0-6-0 shunting tanks from the same firm were now in traffic, Nos. 16420-9 (ex Hyde Park Works) and Nos. 16430-59 (ex Queen's Park Works). The preceding twenty, Nos. 16400-19 (ex Hyde Park Works) were in service on the Northern Division. A further series of fifty engines was being supplied by the Vulcan Foundry Co. as follows: Forty to LNWR section, Nos. 16460-99-the first of which has recently arrived, and ten to the Midland Division, Nos. 16500-9. |
Claughton class engine No. 1327 Alfred Fletcher (L.M.S. No. 5917) had been fitted with Caprotti valve gear as shown on the Italian State Railway locomotive described on p. 308, and is to. be tried against another Claughton, No. 1567 Charles J. Cropper (L.M.S. No. 5908), the latter being similar to the former as before conversion, excepting that it had been provided with new cylinders. In its preliminary trials, the converted engine appeared to have come fully up to expectations.
The following additional engines were running fitted to burn oil fuel: Claughton class, Nos. 63, 119, 163, 208, 1334, 1335, 1726, 2239, 2426, 5901, 5907, 5943, 5983, 5989 and 5994; Prince of Wales class, Nos. 56, 252, 1732, 2392, 5602, 5641, 5645, 5661, 5666, 5702, 5703, 5712, 5731, 5741 and 5774; Standard Compound, Nos. 1112, 1115, 1117, 1118, 1122, 1151, 1155, 1165, 1173 and 1182. Nos. 1821 and 1848, formerly class D simples, and No. 1842, formerly class C simple, had been converted to class " G1 " (superheater). These engines were L.M.S. Nos. 9064, 9022 and 8966 in the order given. Latest withdrawals from service were as follows: Renown class, Nos. 1921 John o' Gaunt and 1973 Hood; Precedent class, No. 514 Puck ; 4 ft. 6 in. 2-4-2T, No. 946 ; 4 ft. 6 in. 2-4-0 , No. 1443 ; N.L.R. 4-4-0T, Nos. 2803, 2813, 2819, 2838, 2847 and 2864 ; Special DX class, Nos. 3006, 3036, 3082, 3132, 3145, 3270 and 3358 ; 17 in. coal class, Nos. 881, 2419, 3318, 3330, 3357 and 3573 ; Special Tank Shunters, Nos. 3340, 3409, 3536, 3538 and 3588 ; and 2 ft. 6 in. shunter, No. 3017

Old Engerth locomotives on French and Belgian railways. R. Greiffenhagen
Re articles by Albert Jacquet the following may be of interest. In the issue of April, 1922, those built for the C. de F. du Midi are described on p. 104, and a diagram given p. 105. There is at least one of these locomotives still at work, or at any rate she was on 17 September 1926. This is No. 334, a 0-6-4 engaged on shunting work at Montauban, on the Bordeaux-Toulouse main line.

Further notes on the early locomotives of the L.B. & S.C. Ry. Fredk. Wm. Holliday. diagram
Re Mr. Bennett's "Further Notes on the Early Locomotives of the L.B. & S.C. Ry." (May 15, 1926, issue of THE LOCOMOTIVE). I well remember the L.B.S.C. tank engine No. 25. I came in contact with her every day, I think, in the year 1867. I enclose a rough sketch. She had a Sharp's moulded bright brass dome cover; a saddle tank with rounded corners; was a four-wheeled coupled engine; the coupling rods were square cottered, not bush rods; the weather board was curved over at the top. The motion was distinctly Mr. Craven's design, but the wheels appeared to me to much resemble "Bury's" design—they were cer-tainly not like any of Mr. Craven's—they always looked odd ones. I should say the coupled wheels were 5 ft. The boiler was pressed to 120 lb.

Further notes on the early locomotives of the L.B. & S.C. Ry. A.R Bennett
I have read with interest F.W. Holliday's recollections of old No. 25, but these must be ascribed to 1869 not 1867, as she was not rebuilt as a coupled engine till May in that year. The 5-ft. coupled wheels would not improbably be those from a Bury engine, since the 5 ft. 6 in. Sharp Roberts' wheels which she had as a 2-2-2 would naturally not serve, and Craven would continue to use up suitable old stuff. Holliday's sketch is accurate except as regards the moulded brass dome cover; this was not of the Sharp design but had a round curved instead of a square base. Other engines with this form of dome were No. 51, 55, 60 and 145. The curved base was invariably painted red by Craven, the top part of the dome being polished bright. The illustration of No. 25 in THE LOCOMOTIVE of October, 1909, is from a sketch I made in 1865. These. domes had belonged originally to some of the Gray-Hackworth engines, part of which had two small square-based domes, like Nos. 53, 56, 58, and part one of these larger curved-based domes on the boiler barrel and a safety-valve pillar on the firebox. No. 25 tank, in its original state, was one of the four outside-cylinder engines (all tanks) designed and built by Craven. These were the 2-2-2 No. 4 (rebuilt as a 2-4-0); the 2-2-2 No. 25 (rebuilt as a 0-4-2); the 4-4-0 No. 144 (rebuilt as a 2-4-0, and the 4-4-0 No. 136 which was never rebuilt.
It would be interesting to learn from Holliday where No. 25 was working when he knew her so well in 1869. As a single tank she worked the Littlehampton branch but as a coupled engine may have 'been assigned other duties. Her career must have extended well into Stroudley's time can Holliday say when she was scrapped? I take this opportunity to correct a mistake which crept into Aylwin's recollections. The statement that the Crystal Palace Company purchased an engine and train and ran a railway service from Norwood Junction was questioned by A.C.W. Lowe, who opined that it was really the West of London and Crystal Palace Railway Company, which had to do with the early stages of Victoria Station. This company's lines were worked by the L.B. and S.C. Ry., but it is on record that they did purchase an engine and coaches in May, 1858, with which a service to the Crystal Palace was inaugurated. On putting this to Aylwin, he agreed to its correctness. Lowe also doubted whether the engine purchased was a Sharp, but on this point Aylwin is quite firm. That being so, Lowe considers that No. 42, built in 1841, was in all probability the engine
.

Three-cylinder locomotives. William T. Hoecker
In reply to E. Joslin's letter in your September issue, the writer wishes to point out that his criticism of the 2-6-4 tank engine No. A890 of the Southern Ry. was confined entirely to the type of valve gear employed for the central cylinder. I am quite familiar with the clearance limitations on the Southern Ry., and feel thoroughly conversant with the theoretical and practical advantages of multi-cylinder engines, but until confronted with indisputable evidence to the contrary, from indicator cards taken in actual running, I cannot admit that any com-bination valve gear will give a satisfactory steam distribu-tion in the central cylinder of a three-cylinder locomotive at all percentages of cut-off, regardless of the "refinements" which the gear may possess. The adoption of a shorter stroke for the inside cylinder will certainly tend to equalise the horse-power developed in the various cylinders at short cut-offs with a combination gear, but this does not eliminate the valve gear defect. In regard to the L.N.E.R. locomotives, Joslin may be interested in the statement of Sir Vincent Raven, to the effect that "he used the three sets of valve gear, and if he went back to rail work to-day he would do the same again." If the Gresley gear is entirely satisfactory, why is it not used on any of the engines sent out from England to the Argentine? And why has the Baldwin Works used Borsig's arrangement of three separate gears on the largest 4-8-2 locomotives yet constructed, which were recently delivered to the Denver and Rio Grande Western Ry.? The fact that there are 74 three-cylinder locomotives of the 4-10-2 and 4-12-2 types in service, or on order for the Southern Pacific and Union Pacific Rys., is no secret. Three cylinders were used on these engines for the simple reason that it was impossible to develop the necessary power with two cylinders within the prescribed clearance and axle-load limitations. The writer hopes that he will not be accused of prejudice against the three-cylinder locomotive, but he believes that if the required power is within the capacity of a properly designed two-cylinder engine, that type of machine will prove more satisfactory and economical, when all factors are considered. Several American railways, in addition to the New York Central, have experimented with three-cylinder locomotives in comparison with two-cylinder engines of equal capacity, but have reverted to the latter type in their most recent orders. The Missouri Pacific, Louisville and Nashville, and Chicago, Rock Island and Pacific may be mentioned in the above connection, and I know of at least one very large American system that would not accept any type of multi-cylinder locomotive as a gift.
The new 4-8-2 locomotives of the New York Central are equipped with the Baker valve gear, giving a maximum cut-off of 82 to 84 per cent. in full gear.. In view of the speeds at which these engines will run, it was not deemed advisable to adopt the "limited cut-off" arrangement. While there are others far better qualified to answer Mr. Joslin's question regarding the "Mountain" type engines of the Northern Ry. of Spain, I may be permitted to say that the primary object in designing these locomotives was to obtain maximum power with minimum weight. The perfeirmarice of the De Glehn compounds in this regard is too well known to require elaboration. If there are any two or three-cylinder simple locomotives in existence, capable of indicating one horse-power for each 87i lb. of total engine weight, the engineering world is still waiting to hear of them.

L.B. & S.C. R. history. William E. Briggs.
Response to: letter from F.W. Holliday on page 33 of Volume 33: A.R. Bennett's contribution to the above subject by the publication of his interviews with G. Aylwin. The locomotives of the L.B. & S.C.R. seem always to have enjoyed a goodly measure of popularity, and there are one or two points of interest connected therewith which to my knowledge have never appeared in print, and so I pass them on in case they are of interest to other readers. The first locomotive to be built at the Brighton works was a 2-2-2 tank engine, numbered 14 and turned out in May, 1852. The last locomotive to be built at the same establishment, under exclusive L.B. and S.C.R. ownership, was the 4-6-4T No. 333 Remembrance so that both first and last were tank engines having a symmetrical wheelbase in each case. But what a wonderful chapter of locomotive development lies betwixt the two, and I have often thought how instructive and interesting it would be to build models of each of above named engines in order to realize more fully the extent of such development, and would like to ask if Bennett, or any other reader, could supply a sketch showing a front elevation of the old 2-2-2 tank of 1852. The illustration on page 59 of your book on "Brighton Loco. History" clearly sets forth the broadside appearance of this engine and would serve a model-maker's purpose very well, but of course a front view is also indispensable for modelling purposes. I should be very grateful if any reader could help in this matter. Another point of interest to students of Brighton locomotive design is that Mr. Stroudley's standard express type was the 0-4-2 type, while his successor R.J. Billinton, adopted the 4-4-0 type as his standard, but Mr. Marsh combined the two in his 4-4-2 or Atlantic type. In Mr. Bennett's articles I had hoped to have seen some reference to the old rebuilt Craven engine Sussex, a noted 2-2-2 in her day, also famous on account of the type of Joy's gear with which she was fitted towards the close of her career.

The late Mr. E. L. Ahrons. M.M. Niven
It is very sad and pathetic to read the "History of the Great Western Locomotives," and to know that the writer of them will never again entertain any of us to share his recollections. In more than one technical paper have I read his historical papers, and can say that although I never knew him in the flesh I had great intimacy with him through correspondence, and I for one feel I have lost a great friend. The late Mr. Ahrons had a style in dealing with engines that never became dry or uninteresting, and humour came into his descriptions from the most unexpected situations. For example, he tells us that the cylinders of an engine placed high on the smoke box were "ensconsed like cats up a tree," and the connecting rods " were like a clothes prop."
In another time he once wrote to me and asked if a certain engine which had a feed heating apparatus on the top of the boiler "still carried the distillery." This engine had just the appearance Mr. Ahrons suggested, for it. looked as if a small vacuum pan like those used on a sugar estate was fitted above the boiler. Many situations claimed humorous allusions, and like Dickens Mr. Ahrons' description of engine drivers, fitters and foremen, made them all seem to become real living creatures, not only to him but to those who read his works. He must have had a good memory, for he described his engines so that even photos or drawings were superfluous.
We can say with the poet :—
"A tale like Waverley we yet may scan,
But shall we read a lay like Marmion."
We certainly owe Mr. Ahrons a great debt ; on whom shall his mantle descend?

The Leeds, Bradford & Halifax Junction Railway and its engines. 390-3. illustration, 2 diagrams (side elevations)
Leeds Central station came into being in 1849 to serve the LNWR, L&YR, Leeds & Thirsk and Great Northern Railways. The Leeds, Bradford & Halifax Junction Railway was worked by the GNR, but in 1858 it decided to worh the Gildsersome branch with its own locomotives. There were two small batches of Kitson & Hewitson tank engines: three 2-4-0 tank engines: Nos. 1-3 (WN 790-1 of 1859). These had side tanks. Two furthrt 0-6-0 tank engines became Nos. 4-5 (WN 794-5/1859) snd are described as pannier tanks. No. 6 was a tender 0-6-0 supllied by Hudswell & Clarke (WN 14/1863). They were all absorbed into the GNR stock in 1863.  See also erratum in Volume 33 p. 32

Technical essays. VII—Works lay-out. 393-4. diagram
The accompanying figure shows diagrammatically a hypothetical lay-out of locomotive shops which, it is suggested, would give a relatively short path for all components, irrespective of whether they comprise new or repair work. It will be seen that the machine shop is divided into bays dealing with heavy work (cylinders), wheels and axles, medium work (e.g., connecting and side rods, axleboxes, eccentrics, piston heads and rods, crossheads, valves and buckles, etc.), small work (including plain turning of brake and motion pins and similar details, and also a battery of automatic machines), and "brass" (using the term in a generic sense to include bronze, gun metal and all non-ferrous metals respectively). Annexes are provided for grinding, toolmakers (including plant for the heat treatment of steel), whitemetallers and millwrights. Incidentally, in equipping the shop, the proportion of grinding and milling machines may be increased with advantage, replacing to a certain extent shapers, planing and slotting machines. All components pass direct from the fitters to the erecting shop, the frames and subsequently the boiler being delivered from the boiler shop. Boiler mountings (stays are not here included in this term) proceed direct from the machine shop to the boiler testing annexe, where they are mounted; having passed the hydraulic and steam tests, the completed boiler is then lagged and goes to the erecting shop. Tender wheels, axles and boxes are sent direct from the machine shop to the tender section of the boiler shop. There the tender is completed, the frames having been marked off, cut out and drilled in an adjacent part of the boiler shop, and the finished unit is then coupled to its engine in the paint shop.
It is most important that the erection of the motion and all undergear should be completed before the boiler is placed on the frames. This facilitates the work of the erector. Further, the boiler should be delivered as a complete unit before erection, so that, having been bolted down and secured in the expansion brackets, only the erection of the ashpan and making of pipe joints remains to be done in the erecting shop.
Turning now to repair work, we would suggest that for the purposes of stripping, the engine be assumed to consist of two units only, viz., boiler and undercarriage. On receipt of the engine from the running department, the boiler is immediately taken out of the frames bodily, and subjected to a protracted steaming with dilute hydrochloric acid. At the same time the frames, cylinders, motion, wheels, etc., are" boshed " piecemeal in a large tank. After this it is possible to make an accurate examination and to estimate fairly closely the extent of the repairs required. The tubes, stays and mountings are removed from the boiler, and also, if necessary, the firebox, and the shell goes direct to the boiler shop. The rest of the engine is stripped and all details, together with the boiler mountings, sent to the fitters, the only exceptions being the springs, which are dealt with in a special section of the smithy, and the cylinders and frames, which proceed to the erecting shop, or if not acceptable there, to the yard temporarily. After re-conditioning, the motion, incidentally, is " tried out" by the fitters on a skeleton frame before being passed on to the erectors. It will be noticed that the erecting shop building includes a finished details stores. This should be stocked with completed details, e.g., piston heads and rods, axleboxes and crossheads, etc., ready for im- mediate use, and so reduce both the time spent in shops by the individual engine, and delay in satis- fying outstation requirements. The same stores may also be conveniently used for pumps, lubricators and other proprietary articles purchased as complete units.
Transport of details between shops can be greatly accelerated by the provision of runways and conveyors, which may of course also be employed in the shops themselves in preference to the more usual runners with their limited range of action. These appliances- should be considered as auxiliary to the travelling cranes, which are essential for the heaviest lifting in the foundry, machine, boiler and erecting shops, and in the lay-out here suggested they would also be necessary in the stripping shop. The more general appointment of engineers as progress men in the shops, who would investigate and analyse delays, and prevent their recurrence, would undoubtedly expedite the manufacture and repair of locomotives in railway works. Under present conditions, the percentage of its life spent either awaiting or undergoing repairs is exorbitant for the average engine, and represents a large sum on the capital involved.

[Southern Ry. of the United States]. 394
The Pacific type engines of the US Southern Ry. used for express work on the main line between Atlanta and Washington, and for hauling the famous Crescent Limited and Queen and Crescent Limited fast trains were decorated in an attractive colour scheme. The tenders, cabs, chimneys, and other projections above the boiler,' as well as the wheels, were painted green, while the whole of the lettering and striping was carried out in gold leaf. The cylinder covers, brass fittings, coupling and connecting rods were highly polished, adding to the smart appearance of the locomotives. In adopting this bright colour scheme the Southern Ry, had reverted to a practice followed in the early days of American railways, when all locomotives were elaborately decorated. It is said the drivers of the Southern line take a personal pride in keeping their engines clean, even on freight service. The engines allocated for working the Crescent Limited had their tenders lettered with the name of the train in gilt, with gold crescents on the sides of the cabs and cylinder covers and on the front number plates.

The report of the Railway Commissioners shows a loss on the railways of £830,671 for the year closed 30 June, 1926, compared with a profit of £32,937 for the previous year. This deficit on the railways coincides with the coming into power of a Labour Government and the reduction of working hours from 48 to 44 per week and no reduction in pay, although possibly a dry spell in the country was a contributory cause.
Two new platforms have been brought into use at the Central Station, Sydney. These are for use by electric trains and will later be used in conjunction with the City railway. Electric trains have commenced to run on the Bankstown line. This line serves a suburban residential district and is nearly 12 miles long.

Correspondence. 407

Three-cylinder locomotives. Diamond.
Two letters have recently appeared in your columns from which it would appear that W. T. Hcecker (response p. 65 Vol. 33) does not approve of combination valve gears for the inside cylinder of three-cylinder locomotives. Since Hoecker.writes from Texas it is probable he has had little opportunity of observing the work of the various classes of three-cylinder engines on the L.N.E.R. fitted with the Gresley gear. To those who are acquainted with the running of these locomotives under all conditions of load and at revolutions per minute equal to any obtained in normal practice no doubts as to their thorough success remain, but the letters referred to do not give a complete picture of the use of the Gresley gear elsewhere. It should therefore be mentioned that the largest non-articulated locomotive in thc world, the three-cylinder 4-12-2 built for the Union Pacific R.R. by the American Locomotive Co., employs. the Gresley gear, and Its builders' advertisements in the technical press are now especially devoted to the three-cylinder engine.
Although Hcecker professes to distrust refinements in gear design and construction, it is generally held that the successful service of valve gears having numerous pin joints is largely dependent upon elimination of wear at the joints and the lightening of all moving masses to the greatest possible extent. In this direction the Great Northern designs would seem to be in advance of general practice, this applying to all motion parts, though it is gratifying to observe apparently similar care has been devoted to the motion of the Southern Ry's Lord Nelson class.
Besides a general antipathy Hoecker mentions only one definite point against the Gresley gear, which he states gives rise at high speeds to the inside cylinder doing above its fair share of the work. No proof is adduced for this statement, but were it true it is surely difficult to devise a more desirable form of varied loading at high revolutions.
To refer for a moment to a different subject, the note on foreign coal on page 364 of your current issue, the adequate boiler and grate dimensions of their locomotives, including especially the three-cylinder classes, appears to have enabled the G.N. section engines of the L.N.E.R. to keep time with all loads to a degree which, as far as my not inconsiderable travel- ling experience goes, has been unique during the past six months, when the fuel has frequently consisted of an incombustible looking slack.

The last of the N.E.R. two-cylinder compounds. R.E. Bleasdale.
The historic "Aerolite".
Re N.E.R. compound Aerolite article by F.W. Brewer it may be noticed that the early 2-2-2 engine, as constructed by Kitson, Thompson and Hewitson, was of the type first developed in 1846 by John Gray, on the Hull & Selby and Brighton railways, and brought into prominence in 1847 by the well-known firm of E.B. Wilson and Co., whose famous Jenny Linds competed with Sharp Bros.' singles for a number of years. The Jenny Linds differed from Aerolite, however, in having their cylinders inside. Although a small engine, Aerolite must have been an attractive exhibit at the 1851 Exhibition; resplendent in a brilliant blue uniform, it vied for popularity with the Lord of the Isles, Cornwall, Folkestone, Little England, The Hawthorn, and Ariel's Girdle.
Of these famous locomotives the only other survivor is the metamorphosed Cornwall, which does similar duty on the L.M. & S. Ry. as the L. & N.E. Ry. Aerolite. In regard to the Worsdell-von-Borries system of compounding, the writer is given to understand that the H.P. and L.P. cylinders were cast together and placed between the frames at different angles, so that the smaller H.P. cylinder overlapped the other. By means of Joy radial valve motion, high pressure steam was admitted to the smaller cylinder, after which it was conveyed by a receiver pipe provided with a flap valve and at a lower pressure to the larger one. In starting 'the engine, the driver could by the action of a hand operated valve, admit steam simultaneously to both cylinders. See also letter drom F. Brewer in Volume 33 p. 202.

Modern locomotive superheating. J.S. Gillespie. 407
See also F.W. Brewer in Volume 33 page 33..
In his interesting article in your issue of 1 ovember 15th on the" Introduction of Modern Locomotive Superheating in Great Britain," I notice that Mr. F. W. Brewer states that the G.W.R. Co. must be regarded as the actual pioneers of latter-day locomotive superheating in this country, the L. & Y. Ry. coming next, and he refers to both experiments as taking place in 1906. It may be of interest to point out that on page 80 of Charles S. Lake's The World's Locomotives, published in 1905, is given a diagram and description of a superheater fitted to one of J. F. Aspinall's inside cylinder Atlantic locomotives of the 1400 class. It would appear, therefore, that the L. & Y. Ry. were the first in the field as regards modern locomotive superheating in Great Britain.

The railways of Great Britain, Lord Monkswell. London: Geoffrey Bles
A large part of the contents of this book were embodied in the first edition published in 1913, but so many changes affectmg British Railways have taken place since then, that it has had to be very much revised and largely re-written, and with new matter added.
It presents a general study of most of the leading departments of railway activity in this country, suitable for the lay reader. Although the author gives credit for the high efficiency of our railway organisation, he severely criticises some features of the administration, especially the tendency to allow political considerations to influence matters that are essentially economic, and the extremely slow progress made in some directions. It is certainly deplorable how some questions have been treated by the railway administrations. Railway officers, individually, are as progressive as other people, but the elaborate officialdom that controls the administration effectually throttles all attempts at initiative. As instances in which requirements have been held up, he mentions the unwillingness to adopt block signals and continuous brakes, the use of superheated steam, the need for acceleration of express trains and making up lost time, improved rail joints, and the introduction of third-class sleeping carriages.
In addition to the many interesting illustrations, there are four gradient profiles of the main lines between Victoria and Brighton, Paddington and Plymouth, via Westbury, Marylebone and Manchester, and Carlisle and Glasgow, via Beattock.

The world's railways. G.G. Jackson, Raphael Tuck & Sons, Ltd.
An entertaining book for boys, the greater part is devoted to the story of the steam locomotive and its work. The author writes in an agreeable style, and although probably most of the information is gathered from other writers, he tells his narrative well, and the younger generation will find it neither tedious or dull. Several of the old yarns about early railway days are of course included. The illustrations include six coloured plates and another six printed in two colours only. The primary colour chosen for the latter is a bright amber, and the result in the case of one of Stirling's" eight-footers " is theStroudley livery and somewhat vivid. The colour of the G.I.P.R. express engine at the head of the Viceregal tram is much too bright, whilst the permanent way should be supported by chairs or pot-sleepers, and not spiked to the sleepers as shown. There are also a number of striking pen and ink sketches of engines and trains. It will make a capital gift-book for boys.

New signalling on the Southern Ry. 408
A nicely prepared and well illustrated booklet describing the Resignailing of the Southern Railway-Charing Cross to Cannon Street, has been published by the Westinghouse Brake and Saxby Signal Co. of York Road, King's Cross. The system of signalling adopted by the Southern Ry. is the"three block" or "four aspect .. system, using long range colour light signals, with the object of giving adequate braking distance to the main line trams without imposing undue speed restrictions on the electric suburban trains; and this is the first occasion on which the four aspect system of colour light signalling, as recommended by the Committee of the Institution of Railway Signal Engineers, has been employed. The diagrammatic plan of the area which has been resignalled which accompanies the booklet, shows the magnitude of the work involved. Besides the building of new signal cabins at Charing Cross and Cannon Street, and the conversion of two others at Borough Market and Metropolitan Junction to electro-mechanical operation, the new signalling system called for the demolition of the large cabin on Cannon Street railway bridge, the closing of three cabins at Belvedere Road, Waterloo East and Union Street, and as the daylight colour light system has been selected—the removal of all semaphore signals in the area.

Horseley Bridge and Engineering Co. Ltd., of Tipton, Staffs. 408
Interesting illustrated brochure entitled A Century of Progress, In this historical account of the firm's activities in general engineering and bridge-building in particular, it is noted that: " In 1837 we have a record that steam locomotives were con- structed at the works, and tested on temporary rails in neigh- bouring fields, to the natural excitement of the local populace, for it should be noted that the first railroad in the country-m fact, in the world, had only been laid seven short years before, in 1830. These engines were among the first used on the railway from Birmingham to Manchester and Liverpool. Un- fortunately the details of that achievement are lackmg; we can simply accept the item as it is-brief and isolated---:but how fascinating a story of those early achievements might have been left us had the men of those days only realised the lively part they were taking in the making of history! .. . It is to be regretted that so far we have been unable to obtain details of these engines, although their service on the Grand Junction Railway has been referred to at times.

Balata belting. 408
A very attractive and well-produced booklet of 64 pages has been issued by E. & J. Dick Ltd., of Greenhead , Glasgow, as a catalogue of their famous Balata belting and driving;; rope. Balata is a vegetable gum of a nature somewhat similar to gutta percha. It exudes as sap from trees Jound principally in the forests of Venezuela and the Guianas. The properties which distinguish it from other gums and make it specially valuable for belting are its great toughness and cornparati ve lack of elasticity. These characteristics in connection with a specially woven fabric ensure a very strong and practically stretchless belt. Also Balata belting will take no harm by being exposed to the weather, to water, or to steam. In addition to full particulars of prices, information is given on the important factors of conveyor practice, methods of splicing, fastening, etc., as well as useful rules for belting calculations.
