The "Rotorua" Express, New Zealand Government Rys. 1 + Supplement (not with copy indexed: presume photograph).
Supplement shows the express train which leaves Auckland every week-day at 10.00 for Rotorua terminus in the Geyserland, or thermal district of New Zealand. The run is 171 miles over a very heavy road. The steep grades between Putaruru (140 miles) at an altitude of 525 ft. above sea level, and Mamaku (158 miles) where an altitude of 1,884 ft. is attained, require a second engine on the train, and to distribute the load on the bridges, etc., it is usual to insert this behind the leading baggage van. The train, when leaving Auckland, is usually made up of twelve well-appointed cars of the American type. The 4-6-2 type locomotive hauling the train was built by the North British Locomotive Co. Ltd. . in 1921. It has cylinders 17 in. by 26 in. with driving wheels 4 ft. 6 in. dia. The working pressure is 180 lb. per sq. in.; the total heating surface 1,625 sq. ft. and the grate area 33 sq. ft. The total weight of the engine in working order is 47 tons, of which 30t tons is available for adhesion. The Vanderbilt pattern tender carries 4½ tons of coal and 3,500 gallons of water, and weighs full 32 tons. They are remarkably fine engines for the 3 ft. 6 in. gauge and have given excellent results in service

London & North Eastern Railway. 1.
The construction of a number of new locomotives has been authorised by the Directors. Eight of these were to be of the latest design of Pacific type, with a working pressure of 220 psi. Nine 2-6-0 tender engines, forty-eight goods engines (J39 class), twenty-eight tank locomotives of a new design for service in Scotland, six suburban tank engines, and twenty 0-4-0 shunting engines. The latest 0-6-2 tank engines delivered by Hawthorn, Leslie & Co. were Nos. 2670 and 2671, while the North Road Works hadcompleted Nos. 2718, 2719 and 2720 of the 0-6-0 J39 class. Darlington works were also building a large four-cylinder express engine with water-tube boiler, carrying a very high working pressure.

Paris, Lyons & Mediterranean Ry. 1
It is reported that this railway has placed an order with Henschel & Sohn, of Cassel, for a high-pressure locomotive, the boiler of which will be designed to carry a working pressure of 1,000 psi. It is estimated the new locomotive, when empty, will weigh 100 tons. See also p. 59.

Institution of Locomotive Engineers.. 3
Railway rolling stock and permanent way was the subject of Paper 244 read at a joint meeting of the above Institution and that of the Permanent Way Engineers on Thursday, 13 December 1928 by H. Holcroft. By way of preface to his remarks on the relationship existing between the locomotive and the track, the author visualised the track as a smooth, special form of path on which the locomotive as a tractor had to rely for its ability to do the work imposed on it. The permanent way has three functions:-(1) To support the steel rails and form a path, (2) To guide the vehicles in a given path, (3) To provide the reaction to the tractive effort, or, conversely, to the braking force. The locomotive and track combined to form the railway transport machine, and either one would be of no value by itself as a money-earning item.
Ho1croft proceeded to illustrate the effect the track had on the wear of tyres, flanges, etc.; also the effect the inequalities of the track had on the mechanism of the locomotive; the stresses imparted to bridges, etc., were also discussed. J. Clayton, Vice-President, presided, and opened the discussion by complimenting the reader of the paper on its excellence. Messrs. Williams, Tomes, Devon, Lelean, Allen, and others took part in the discussion which followed.

London Midland & Scottish Ry. (L. & N.W. Section). 3
The L. & N.W. Ry, renumbering was finally completed during November. One of the last engines to be renumbered was 4-6-0 mixed traffic class No. 2424, this being now L. M. & S. 8732. Further Class 4 0-6-0s—the last of the present order—had been completed and turned out at Crewe, Nos. 4551-6. After being broken in, these engines will be transferred to the Midland division. Except for painting, the new 2-6-0 mixed traffic engines, Nos. 13100-9, were all finished and in service by  31 December 1928. They were working from the Crewe South shed. Later on they were scheduled to return to the works for painting, and then despatched for service on the Northern division. The first of a series of enlarged 0-8-0 superheater freight engines would shortly be put in hand at Crewe.
There were six 4-6-0 Claughton class locomotives adapted to the Northern division gauge in service. Of these, five were noted in the December issue. The remaining one was No. 5915 Rupert Guinness (old 668). Others of the same type at present working on the Midland division bore the following numbers :-5900, 5923, 5932, 5944, 5949, 5960, 5971, 5973, 5974, 5977, 5978, 5984, 6001, 6005, and 6025. No. 9665 (formerly R.O.D. No. 1853), which was turned out at Crewe, completed the series of 2-8-0 M.M. engines which were taken over in 1927.
Recent withdrawals include the following passenger tender engines: 4-6-0 Experiment class No. 5492 Sanspariel ; 4-4-0 Precursor class Nos. 5234 Velocipede and 5264 Pacific; 4-4-0 Renown class Nos. 5160 Resolution and 5167 Jupiter; also class B 0-8-0 compound No. 8916 (old No. 2561).

Three-cylinder 4-6-0 express locomotive, L. & N.E. Ry. 4-5. illustration, diagram (side & front elevations)
Requirements in the eastern counties imposed serious demands upon the locomotive stock inherited from the old Great Eastern Ry., and though a certain number of classes derived from other constituents of the London and North Eastern group have been employed in this area, the peculiarities of the line, with its many restrictions, have rendered the construction of specially designed locomotives very necessary and desirable. Iillustrations of the first engine of an entirely new class, officially known as Type B17, which we understand is intended for service in East Anglia. Although it embodied the most characteristic features of Gresley's distinctive practice, it is the first locomotive of his design to have the 4-6-0 formation, a type which in this instance results in a remarkably compact, and for its size and weight, decidedly powerful, engine which should be admirably suited to the conditions it is intended to meet. As might be expected from the excellent performance of all the three-cylinder types originated on the Great Northern line, these latest engines, like the Shires with which they have many features in common, make use of three high-pressure cylinders, but are different in that the drive is divided, the inside cylinder acting upon the leading coupled axle and the external pair upon the middle coupled wheels. The diameter of 17½ in. and the piston stroke of 26 in. is common to all cylinders, and the distribution is effected by Walschaerts-Gresley gear in its latest development, that is to say, with the rocking arms located behind the cylinders, as in the Shire class, instead of in front of the valve chambers. This arrangement permits the inside cylinder to lie well ahead, and also facilitates access to the piston valves from the front end. These are of the inside admission type, 8 in. in diameter, and are set to give a maximum cut-off of 65 per cent. in full gear.The total evaporative heating surface being therefore 1,676 sq. ft. and the combined surface 2,020 sq. ft.Ten of these engines have been built at the Hyde Park Works of the North British Locomotive Co. Ltd. (Nos. 23803 to 23812 of 1928). The new engines were run in on the slow trains between Edinburgh and Glasgow. The following are the numbers and names:- 2800 Sandringham (illustrated), 2801 Holkham, 2802 Walsingham, 2803 Framlingham, 2804 Elveden, 2805 Burnham Thorpe, 2806 Audley End, 2807 Blickling, 2808 Gunton, 2809 Quidenham

Great Western & Southern Jt. Rys. 5
On the Easton and Church Hope Ry, a wire screen 211 yards long had been fixed alongside the line to safeguard the trains from rocks falling from the. cliffs. In the event of any of the wires of the scre.en bemg broken by a fall of. rock, signals working in conjunction WIth It are automatically put to danger and warning bells in the signal boxes at Easton and Port1and were operated. Hitherto, a flagman had to be in attendance to take precautionary measures in the event of a fall of rock. A similar system has been in use on the Callender and Oban Ry, im the Pass of Brander for many years.

Great Western Ry. 5
On the former Midland & South Western Junction line between Andoversford Junction and Cirencester, and on the Cardiff Ry section between Whitchurch and Rhydyfelin conversion from double to single track had been completed.

Meeting held at Denison House on 31 January H. Kelway-Bamber, vice-president, read a paper entitled "Modern steam rail cars in service." Sir Henry Fowler, KB.E., was in the chair. In his introduction of the subject, Bamber mentioned the services in which the Light Rail Car may be most usefully employed. He then quoted representative particulars of the steam rail motor cars which were introduced on many of the British railways about twenty-five years ago, and on comparing the figures with those of modern rail cars showed that the builders have succeded in effecting a reduction of about 40 per cent. in the dead weight per unit of seating capacity, while retaining the tractive force of the majority of the old cars. Recent developments in the construction of light multiple-cylinder fast running engines, deriving their power from highly superheated steam at a pressure of about 300 lb. per sq. in. (compared with about 170 lb. for the cars of twenty-five years ago) produced in small quick-steaming boilers, and geared down to suit the required train speeds, have enabled considerable improvements to be effected.
To meet different service requirements, rail cars of the Sentinel-Camrnell type are geared either to 500 crankshaft revolutions at a car speed of 38 m.p.h. or 500 at 30 m.p.h., but these ratios are not interchangeable on anyone car. The maximum outputs of the six-cylinder engines vary from 50 B.H.P. at 5 m.p.h. to 130 H.P. at 20 m.p.h., 116 H.P. at 30 m.p.h. and 100 H.P:. at 50 m.p.h. on the 500 rev. at 38 m.p.h. gear, and 64 H.P., 110 H.P., 115 H.P., and 87 H.P. respectively on the 30 m.p.h. gear. In the engines fitted to the latest cars, steam admission and exhaust is controlled by Poppet valves, operated by sliding cam shafts having three positions, the percentage of admission being 70, 45, and 27 respectively. The author then discussed the steam consumption, boiler and steam-raising capacity, rate of evaporation, rate of firing, the effect of car mileage on revenue earning capacity, and the overall working costs. Finally, he gave some interesting experiences of the latest Sentinel-Camrnell rail cars in traffic working. An interesting discussion followed the chairman's remarks.
J.R. Bazin, of the Great Southern Rys., Ireland, was the new president of the Institution, and the following members of council had been elected :- A. Devon (Rendel, Palmer & Tritton), W.S. Edwards (W. G. Bagnall Ltd.), E. Graham (London Electric Rys.), L.J. Le Clair (Westinghouse Brake & Saxby Signal Co.), J. Mitchell (A.B.C. Coupler & Engineering Co.), S.J. Syrnes (L.M. & S.

High pressure locomotive for the L.M.S.. Ry. 59
With reference to the note on page 1 of our last issue, an, nouncing the fact that the Paris, Lyons and Mediterranean Ry. have placed an order with Henschel and Sohn for a high- pressure locomotive. We now learn from the Superheater Co. Ltd. that the boiler for this locomotive is to be of a similar design to that built by Henschel's to the designs and patents of their Associate Company, The Schrnidt.'sche Heissdampf G.m.b.h. for the German State Rys., extended trails of which have taken place during the last two years. The North British Locomotive Co. Ltd., are building for the Superheater Company Ltd. and the London, Midland and Scottish Ry., a similar boiler having 900 lb. pressure in the high-pressure and 250 lb. in the low-pressure boiler, and this boiler is to be fitted to an engine of the Royal Scot class. The design of the boiler is being directed by the Superheater Company, and will be built to the inspection and requirements of the L.M.S. Ry. As the engine will be a three-cylinder compound, certain modifications will be required to the inside cylinder.

4-6-0 four-cylinder Claughton class engine, No. 5908 Alfred Fletcher (old No. 1327), which was fitted with Caprotti valve gear as an experiment was running rebuilt with the new standard boiler, thus completing the series of twenty which were to be so fitted. Of these engines, ten still retained the original Walschaerts motion, these being numbered 5906, 5910, 5953, 5970, 5972, 5986, 5993, 5999, 6004, and 6017. The other ten engines, all of which are fitted with Caprotti valve gear, bear the Nos. 5908, 5927, 5946, 5948, 5957, 5962, 5975, 6013, 6023, and 6029. The output of new locomotives at Crewe during 1928 comprised sixty 0-6-0 standard freight engines, Nos. 4447-56 and 4507-56 and ten 2-6-0 mixed traffic engines, Nos. 13100-9. In addition, about twenty-two 0-8-0 mineral engines were converted to superheaters; also the rebuilding of the twenty Claughrons, above mentioned, was completed during the year.
Since the appearance of the Royal Scot class engines, certain L. & N.W. engines have continued to carry the names in cases where they clashed with those of the newer engines. To avoid further confusion, however, the older name-plates were to be removed forthwith. About nine engines are affected, including No. 5468 Lady of the Lake (Experiment class), which is already nameless.
0-6-2 side tank coal engine No. 7641 (old No. 2486) had been fitted for motor service.
Withdrawals included the last remaining four-cylinder mineral compounds, viz, 0-8-0 B class, Nos. 8919 and 8938, and 2-8-0 F class No. 9614. Thus, all the Webb compound engines, both passenger and goods, had disappeared. Precursor class 4-4-0 No. 5238 Ilion had also been withdrawn.

L.M. & S. Ry. (Midland Section). 59
Five new type 0-6-0 shunting tank engines for service in dockyards, etc., had been completed at Derby, Nos. 11270-4. One of these engines, No. 11271, was working trial at the Birkenhead docks. A description and illustration of one of these engines appears on page 45.
Further 2-6-4 passenger tank engines (2300 class) were under construction at Derby, Nos. 2325 upwards. Several of the No. 1 class L.T.S. 4-4-2 passenger tank engines were running fitted with the vacuum brake, in addition to the Westinghouse brake.
The demolition of the Cofton Tunnel, on the Birmingham and Gloucester line of the L.M. & S. Ry., near Barnt Green, was successfully completed late on Saturday night, 26 January.

Recent accidents. 66
Severe head-on colliision on 27 June 1929 at Darlington Bank Top between a Scarborough to Newcastle excursion hauled by Atlantic No. 2164 and and a parcels train hauled by 4-6-0 No. 2369. 25 passengers killed and 45 seriously injured in telescoping of passenger stock. Sir John Pringle attributed blame to driver of parcels train for failing to observe signals during shunting. On 17 August a Cambridge to King's Cross express hauled by Atlantic No. 3253 hit a lorry loaded with lime on the level crossing at Shepreth. The driver of the lorry and the fireman of the locomotive were killed and the driver of the locomotive was severely injured and the locomotive was beyond repair. Colonel Trench blamed the lorry driver and noted that consideration should be given to improving the safety at level crossings.  On 9 July a light engine (4-4-0) collided side-on with an electric train from London Bridge to Epsom Downs near London Bridge leading to the deaths of two passengers and serious injuries to five others. Colonel Mount attributed the cause to the failure of the driver of the light engine to understand the new signalling. On 19 September there was a buffer stop collision at Charing Cross which led to telescoping. Pringle was critical of the buffing arrangements of the rolling stock and attributed the blame to the motorman due to failuure to operate the Westinghouse brake correctly. On 29 July an LNER from Hull to Blackpool was at Midland Junction, Manchester when it was hit by a light engine. Both the LNER and LMSR guards died. Colonel Trench blamed the driver of the light engine

Smith Brothers & Co. (Hyson) Ltd. 118
,Hyson Green Valve Works, Nottingham, in referring to our article on the Pressure Gauge, inform us that Mr. Sydney Smith, who patented the first steam gauge, founded their company III 1847 for the purpose of manufacturing this gauge and other steam fittings. They have supplied a large number of th.e Smith type of gauge to the L. & N. W. Ry., and they are still made by them, as well as by Messrs. Sydney Smith and Sons, of Basford. In addition to its pressure gauges section, t~e firm now specialises in whistles and syrens, injectors and ejectors, safety and reducing valves, radiator fittings, super- heat valves, asbestos packed cocks, etc. An amusing order was. received by them from an Indian Rajah. He required an Ill~trument that would roar like a tiger. After many expenments a steam syren with a "tiger roar" was designed and made. The Rajah was delighted. and expressed his gratitude in glowing terms.

Obituary. 135
It is with great regret that we have to record the death of. Robert Whyte Reid, vice-president for works and ancillary undertakings of the London Midland and Scottish Ry., which occurred at Derby on M;rch 28. Reid, who was 44 years of age, joined the Midland Ry. in 1909. In August, 1919, he toured the principal carriage and wagon buIld!ng works of the United States to study methods of construction, repair and administration, and on his return was responsible for the re-organisation of the Derby works and the introduction of mass production methods in the manufacture of carriages and wagons. From the formation of the L.M. & S. Ry. until the end of 1926 Reid was carnage and wagon superintendent, when he was appointed vlce :presldent on the headquarters reorganisation. He was president of the Institution of Locomotive Engineers in 1925. He was awarded the C.B.E. for services in connection with the design and construction of special rolling stock for war purposes.

Lord Montagu of Beaulieu, 135
Died on 30 March 1929: went into the Nine Elms Works of the L. & S.W. Ry. in eariy life, and became not only a fireman but an expert engine driver. He was. a thorough enthusiast on all matters concerning locomotives, their history, construction and maintenance.

Karl Benz. 135
Another expert in locomotive matters, Dr. Karl Benz, died at Mannheim on 4 April 1929. He passed his early days at Karlsruhe, and was much interested in all that appertained to railway locomotives, even in later life, when he had devoted his attention to motor cars, in which direction he was a pioneer.

Railway Club. 135.
The monthly meeting of the Railway Club was held on 4 March, at Headquarters, 57 Fetter Lane, E.C.4, Kenneth Brown, President, in the chair. An interesting paper was read by G.S. Walker on "Crime and the Iron Road." Walker dealt with the following murder cases: (a) Mr. Bnggs by Muller on N.L. Ry. on July 9, 1864 (the first murder committed on a British railway)' (b) Mr. Gold by Lefroy on L.B. & S.C. Ry. on June 27 1881' a murder which began in Merstham tunnel and was only completed m Balcombe tunnel, 17 miles further on; (c) Miss Elizabeth Camp by an unknown assailant (an unsolved mystery), on February 11, 1897, on L. & S.W. Ry.; (d) Mr. Pearson, by George Parker at Vauxhall, L. & S.W. Ry., on June 17, 1901; (e) another unsolved mystery, the murder of Miss Maria Sophia Money, in Merstham tunnel on September 24, 1905. In each case Mr. Walker traced how the murderer was brought to justice, also what little was elucidated in the two unsolved tragedies. The paper was brought to a conclusion by the story of the Netherby Hall burglary, which happened in the Carlisle area many years ago. Though not originally a railway crime the three desperadoes were secured by railway servants when trying to make their escape, after acts of violence following the robbery, by goods train to the south. All three were hanged.
The paper was followed with much interest by members, and hope was expressed that at some future occasion Mr. Walker would contribute a further paper on the subject. The following visits and excursions have been arranged :- Sat., May 11, Camden Sheds, L.M. & S. Ry. Sat., June 1, Romney, Hythe & Dymchurch Light Ry. Sat., July 20, Wimbledon and Sutton new line.
The following visit has taken place :- Sat., April 13, the new power signal box at London Bridge station. followed by the Croydon signalling school, S. Ry.

Special boat train.  135
On Saturday, 6 April 1929 a special boat train was run by the G.W. Ry. from Paddington to Cardiff Docks, in connection with the first sailing of an Atlantic liner from that port— the S.S. Montrose. A train of five bogie coaches with restaurant car, hauled by engine No. 4093 Dunster Castle, conveyed about 100 passengers, and another 200 joined the boat at the docks.

Southern Ry. 135
The three-cylinder 4-4-0 passenger cngmes, under construction for the London and Hastings and Folkestone services, are to receive the following names of schools in the South of England :- Eton, Winchester, Welimgton, Charterhouse, Lancing, Tonbridge, Sherborne, Duliwich, Westminster, and St. Paul's. The 1929 building programme also included ninety new corridor coaches, four of which were restaurant cars, as well as fifty passenger luggage vans, while the wagon building programme includes over 1,000 vehicles of various descriptions.

Correspondence. 135

Wm. T. Hoecker.
On page 48 of your February issue there are some remarks regarding the relative proportions of superheating surface used in British and German locomotive boilers. In connection therewith, the following facts are submitted:—
In the official "Merkbuch für die Fahrzeuge der Reichbahn" there are listed 104 types of standard gauge steam locomotives equipped with Schmidt large-tube, or type HA," superheaters. Using the official figures, it is found that in these 104 different types of boilers, the aueraqe ratio of superheating surface to evaporative heating surface is 1to 3.30.
To render this comparable with British figures, it is necessaryto take into consideration the fact that, in Germany, heating surfaces are calculated from the side in contact with fire and gases. In the boilers under discussion, multiplying the superheating surface by 0.8, and the evaporating heating surface by 1.09, will convert the value of these surfaces to the English basis of water contact, with sufficient accuracy. The resultant ratio of superheating to evaporative surface is 1 to 4.50.
For thirty-five new types of British main line engines (except Great Western) illustrated in THE LOCOMOTIVE during the past five years, the average ratio of superheating surface to evaporative heating surface is 1 to 5.1. This is not far from the German figure given above, and the difference is partly explained by the presence of exhaust-steam feed-water heaters on sixty-six of the 104 German engines. It is scarcely necessary to explain that engines having feed-water heaters require a greater proportion of superheating surface than those without such heaters, if the same degree of superheat is to be attained. The feed-water heater is the real reason for the increasing adoption of the small-tube or type HE," superheater in America.

H. Dixon Hewitt Light Rail Units for Passenger and Freight Work
Writes in connection with L. Ballard's paper on Light Rail Units for Passenger and Freight Work, of which we gave an abstract in our last issue, and encloses a photo. of a rail motor at Westerham in August, 1905. This resembles the Peebles car tried on the Midland Ry., but we are unable to say if it is the same. The S.E. & C. Ry. steam cars came out about four months later. There were at first only two, but they finally increased to nine. These were long bogie cars with an engme end of the small locomotive type, not cased m. They worked the services on the Dunton Green and Westerham, Otford and Sevenoaks, Dover and Sandgate (reversing at Sandling JunctIon), Beckenham and Norwood, Orpmgton and Crystal Palace, and he thinks also on the Gravesend and Port Victoria, Isle of Sheppey Lt. Ry. and the Lydd, Romney and Appledore lines. Also to supplement the services between Gravesend and Dartford, etc. In spite of alleged trial tnps m which 50 m.p.h. was attained, passengers spoke of their low speed. They were all withdrawn from service prior to the Great War [WW1}.

The Model Railway Club Exhibition. 169
No one who visited this exhibition, which was held at Kingsway Hall on the 17-20 of April, could fail to be impressed with the remarkable excellence of the various models shown and the efficient performance of the various trains actually running, which latter ranged from relatively large steam engines hauling loads of passengers to almost microscopical electrically propelled loco- motives dealing with various kinds of rolling stock upon a beautifully laid-out miniature railway system complete with all details and scenic effects. Although the models were for the most part constructed by persons not professionally concerned with locomotives or railways, the accuracy of reproduction, combined with the ingenuity in overcoming difficulties peculiar to small-scale machinery, was worthy of commendation by the most critical engineer; and it is evident that the widely spread and ever-growing pursuit of model railway construction must have no little intellectual value in fostering habits of acute observation and dexterous craftsmanship. It would be difficult, and perhaps a little invidious, to signalise any particular exhibit amongst so many admirable specimens; but mention must be made of a little shunting tank loco- motive, made to a scale of 7 mrn.yf t. which included in the minutest detail all the most modern devices and accessories -Knorr air and water pumps, feed heating apparatus, full Walschaerts valve gear, etc., etc., and also to a 4 mrn.yft. scale model of the Royal Scot complete with valve gear which ran, with an appropriate train, an aggregate distance of many miles during the course of the exhibition. There was a very fine display of coaches, the Great Western Ry. appearing to be the most favoured line in this respect. Signalling, track, etc., were also well represented, together with a great variety of goods stock. From our observations of previous exhibitions we should say there is every sign of progressive improvement in the objects shown, and it should be gratifying to all concerned with railway matters that there is thus manifested so much interest by a wide and intelligent public at a time when the companies for obvious reasons find it desirable to emphasise the importance of the railway to our vital needs and services.

False relics of the past. E. A. Forward.
The article by Mr. R N. Appleby Miller on the supposed relics of a Blenkinsop rack locomotive, found at the Newburn Steel Works, Newcastle, which appeared in the April number of THE LOCOMOTIVE, prompts the writer to give the true story of these "false relics." In 1886, John Spencer & Sons, of Newburn Steel Works, exhibited these rack rails, wheels, etc., at the Liverpool Exhibition, but clearly stated that they had been cast from original patterns which were in their possession. They had, however, the incorrect Wylam tradition attached to them. Front the evidence of existing letters written in 1893 by the Tyne Hematite Iron Works Co., who had been the lessees of the works of the original Tyne Iron Co. since about 1870, it appears that on taking over those works they found some old patterns of rack rails, cogged wheels and carrying or wagon wheels. Between 1870 and 1877 new castings were made from these old patterns, and in the latter year sets consisting of two rack-rails and a cog wheel were said to have been distributed to various institutions in this country. Such a set was sent to the South Kensington Museum in 1893. It is thus practically certain that the material now found at the Newburn Steel Works is part of that cast from the old patterns at the Tyne Hematite Iron Works between 1870 and 1877, and no doubt preserved at Newburn after being exhibited at Liverpool in 1886.
The length of the axles fitted to the wheels was no doubt dictated by the Wylarn tradition and has no historical significance. It is well known that the Middleton line at Leeds had the rack on one side only, and doubtless the Kenton and Coxlodge line was similar, as, apart from the cost, it would be difficult, if not practically impossible, to satisfactorily work an engine with a rack and cog wheel on both sides. The writer is unable to detect a double rack and wheel on the print in Walker's Costume of Yorkshire in 1814, and is of opinion that the weight of evidence is decidedly against the existence of rack rails on the Wylam line. It would, therefore, appear to be highly probable that the old patterns had been used for the material required by the Kenton and Coxlodge line.

Northern Ry. of France locomotives, etc. Wm T. Hoecker. 169
On pages 74 and 75 there are a welcome photograph and an excellent drawing of the Super-Pacific locomotives of the Northern Ry. of France. Various articles in other periodicals indicate that some uncertainty exists concerning the weight of these engines. In adding the several axle loads shown on the drawing above referred to, it is impossible to arrive at a total, because of a misprint of the figure under the trailing axle. It may, therefore, be of interest to quote the following extract from a letter which I received from the chief engineer of material and traction of the Cie. du C. der Fer du Nord, under date of 29 January 1929—
The weight of our locomotives 3.1201-3.1240, in their present condition, is 97,600 Kg.
This is 3,140 Kg. more than is shown on the original diagram of these engines, which was reproduced in THE LOCOMOTIVE for September, 1924. The increase is, of course, due to the feed-water heater and pump, and the additional water contained in these accessories.
Re some discrepancies in the table on page 99. The weights of the Pennsylvania RR 2-10-0 engines of class 1-1-S are given in the P.R.R. Bulletin No. 32, and in several publications of the Baldwin Locomotive works, as follow:-
On coupled wheels, 352,500 lb.
Total engine in running order, 386,100 lb.
The weights listed by Poultney are those of the first experimental 1-1-S engine, which was illustrated in your January, 1918, number. The later standard engines of this class have type E superheaters and Worthington feed-water heaters, and are somewhat heavier than the original locomotive.
Poultney also quotes the superheating surface of these engines as 2,469 sq. ft., but this figure should not be used for comparative purposes. Contrary to the practice of all other American railways and locomotive builders, the Pennsylvania RR calculates superheating surfaces from the side in contact with combustion gases. The superheating surface of the 1-1-S engines, calculated from the side of the tubes in contact with steam, is given by the Baldwin Locomotive Works as 1,986 sq. ft.

Southern Ry. 2-6-0 locomotives. C.F. Dendy Marshall. 169
I think you are mistaken in saying that the new Southern Ry. 2-6-0 engines are suitable for a maximum speed of 70 m.p.h. In my opinion, such a speed is highly dangerous for a locomotive with a pony truck. In order to render an engine of this kind safe at speeds in excess of 50 m.p.h. it should be fitted with a Krauss-Helrnholtz, or Zara, bogie, which is used extensively on the Continent. Engines with pony trucks were tried for fast trains in the United States in the early 'nineties, but were quickly dropped, owing to the unsatisfactory steering of the engine.

Memomorial Tablet to Matthew Murray. 195. illustration.
Matthew Murray has been called the Father of Leeds Engineering. The memorial is in the form of a bronze tablet affixed to the wall of a factory in Water Lane, Leeds, on the site of the Round Foundry built by Fenton, Murray & Wood. The Lord Mayor of Leeds (Alderman D.B. Foster) unveiled the tablet on 8 May 1919 and in his speech described Murray as one of the greatest preparers for the present mechanical age. Mr. E. Kilburn Scott, chairman and secretary of the memorial fund, narrated the life work of Murray and explained the outstanding events of his career. To Murray belonged the credit of building the first successful steam locomotives in the world in 1811. These ran on the Blenkinsop rack-railway between Leeds and the Middleton Colliery from 1812 to 1835. Lieut.-Col. E. Kitson Clark, who was present at the unveiling as vice-president of the Institution of Mechanical Engineers, and as representing the Newcomen Society, said that his grandfather was bitten by the idea of making locomotives, and he represented the third generation making them. Murray was undoubtedly very much ahead of his time, and was the embodiment of the courageous, common-sensed, able, determined, dogged, practical, and at the same time, imaginative genius which constituted the British character. When they realised that in the City Square there was a statue of James Watt, and their own man of .Leeds was left out, it was time to rectify the omission. To complete the memorial, another tablet is to be erected at the Institution of Mechanical Engineers, London, a prize fund is to be formed at the Leeds Technical College, and copies are to be made of Murray's models in the Science Museum, South Kensington, for the Leeds City Museum.

Pullman cars from Paddington to Plymouth Docks. 195
On Friday, 10 May 1929 the Great Western Ry. ran a train of six Pullman cars from Paddington to Plymouth Docks and back as a trial: the train consisted of the three first-class cars, Ansonia, Plato, Thelma, and three third-class cars. The train, headed by No. 4073 Caerphilly Castle, left Paddington at 09.15 and ran non-stop to Millbay Docks, the journey occupying four hours. The return journey also took four hours, Paddington being reached just after 19.00. Officials from Paddington and the Pullman Car Co. travelled with the train.

F.W. Brewer. 2-4-0 passenger engines, "3206" class: Great Western Railway. 256-8
William Dean design of 1889. Swindon numbers 1137-1151: running numbers 3206-3225. They haad 6ft 2in coupled wheels and double frames. Originally they had 15 x 24in cylinders, 1468.82 ft2 total heating surface, 19ft2  and 150 psi boiler pressure. From 1899 most were rebuilt with Belpaire boilers, some were of the doeless type with the safety valves in the middle of the barrel, and some with domes. At the same time larger cylinders were fitted (18 x 26in) and boier pressure was increased to 180 psi. Superheaters were fitted to the domed variety. In 1924, two of the engines, Nos. 3222 and 3223 had the overhang at the front end increased from 4 ft. to 4 ft. 9 in., the length of engine and tender overall thus becoming 53 ft. 5 in., as compared with the 52 ft. 8 in. of the other rebuilds. These two engines, moreover, were the only representatives of the 3206 class fitted with piston valves. All had the top-feed device. The dome is in all cases carried on the back ring of the boiler, and enclosed the regulator valve. This valve was originally fixed in the smokebox, not withstanding that the engines were built with domed boilers. The Barnums, which were often employed on the West and North expresses, from Bristol to Shrewsbury, and also Swindon to Bristol and Swindon to Gloucester and Cardiff, acquired their nick-name in connection with working the old Barnum Show trains. The engines of this notable class which had been broken up were :-Nos. 3208 and 3224, in 1926; and Nos. 3215 and 3220, in 1927. A fifth, No. 3209, was condemned in March, 1929. It was one of those which had been superheated, and it supplements the eight examples of that description, the numbers of which have already been quoted. The rebuilding of the 3206 class was commenced in William Dean's time, and was continued by G.J. Churchward. The then chief mechanical engineer of the G.W. Ry., C. B. Collett, has also contributed his share in keeping the engines up-to-date, in so far as it has been in the interests of economy to retain them in service.

London & North Eastern Ry. 258
The order for fifty J39 0-6-0 goods engines had been completed at North Road Works, Darlington, the last five being Nos. 2738 to 2742. The series commenced with No. 2691.
One of the A3 class Pacifies, No. 2580 Shotooer had been fitted with the A.C.E.I. feed-water heater, and the two cylindrical reservoirs as fitted on the 4-4-2's Nos. 728 and 2206 had been dispensed with, and a fitting provided on the front of the smokebox. Viewed from the front no chimney is visible, giving the engine a very formidable appearance. One of Sir Vincent Raven's Pacifies, No. 2404 City of Rtipon was being fitted with a coned boiler. Several 2-6-0 engines of the K.3 class hade been completed at Doncaster Works of which Nos. 1300, 1312, 1318, 1331 and 1364 are working on the North Eastern section.

J.G.B. Sams. Modification of British goods equipment. 258-9
Freight transport may be divided into thr classes—minerals, always in bulk, large goods consignments and "smalls," each having specific problems for the railway operator. Present railway methods have slowly evolved out of an easy-going and practically non-competitive past that has perhaps imbued present-day managements with too great sense of permanent stability for the transport business and it is due to the changes in these conditions since WW1 that a drastic overhaul has become necessary.

Presentation to Sir Robert Hadfield.. 270. illustration  (portrait)
Ceremony took place at the East Hecla Works of Hadfields Ltd., Sheffield, when the presentation of a bust of himself was made by the directors to Sir Robert Hadfield, the chairman of the firm, in recognition of his seventieth birthday. The presentation was of an informal character, for Lady Hadfield was the only one present, apart from the directors of the firm, Mr. P. B. Brown, Major A. B. H. C1erke, Mr. J. P. Crosbie, Mr. W. B. Pickering, Mr. W. J. Dawson, and Commander E. H. M. Nicholson. Mr. P. B. Brown, the managing director, made the presentation, remarking that the bust, the work of Mr. F. J. Halnon, R.B.S., had been prepared without Sir Robert's knowledge. Fearing that it might be difficult to persuade Sir Robert to sit for the artist, they took a risk and commissioned him to proceed with the work from snapshots taken at various times. It was not because he was a man of distinction, recognised by the world as the greatest living metallurgist, that they had taken this action. It was much more personal. They wished him to accept it as a mark of esteem from his colleagues, who for many years had been privileged and had felt it an honour to be associated with him in the building up of this business. The bust was uncovered by Major C1erke, and Sir Robert, in replying. thanked the Board for the kind thought that had prompted the presentation. He was particularly delighted it had taken the form of a bronze bust, and assured them that he greatly appreciated and valued the kindness that had been shown him.

Railway development. Frank Smith.
M.P. for Nuneaton Division of Warwickshire observed that Lord Monkswell was again in the saddle of that pet hobby horse of his on which he periodically charges full tilt at the railway system of Great Britain. Unhappily for his case he alleges that "the official railway attitude to any suggested improvement is and always has been, 'This is quite unnecessary; nothing needs improving.''' The words had scarcely left his Lordship's lips when a new Cornish Riviera express steamed off from Paddington to celebrate the silver jubilee of that remarkable train. Compared with its predecessor the new express was improved at every possible point—larger coaches (the widest in the country); a huge locomotive; a train nearly twice as long and more than twice as heavy; electric light for gas; radiators instead of steam pipes; vitaglass to let in all the sun instead of ordinary window glass; and a journey forty minutes quicker. Lord Monkswell's enthusiasm for railway reform really must not be allowed to overleap aU the known facts for an end must be put to this practice of crying down anything and everything British. Do any of your readers know a country in the world where they can travel in greater comfort than they do at home?

American Pacific type locomotives. Wm. T. Hoecker
In his most welcome article on page 196 of your June number, Mr. Poultney has unfortunately omitted any mention of what is, so far as published records go, the heaviest and, as regards boiler capacity, the most powerful group of Pacific express engines running in America to-day. I refer to the locomotives Nos. 325-328, built for the Richmond, Fredericksburg and Potomac Ry, by The Baldwin Locomotive Works early in 1927. Although their maximum tractive force is 1,420 lb. less than that of the Baltimore & Ohio's President class, these R.F. & P. engines have a more favourable factor of adhesion a boiler 4 in. larger in diameter, a larger grate, and a larger superheater. Their principal dimensions are as follow:-
Weight in running order (without booster) 332,(i)() lb.
Adhesive weight 205,300 lb.
Maximum tractive force 48,580 lb.
Cylinders 27 in. by 28 in.
Driving wheels diameter 75 in.
Boiler pressure 210 lb.
Evaporative heating surface 4,175 sq. ft.
Superheating surface 1,078 sq. ft.
Grate area 75.8 sq. ft.
The maximum running speed allowed for these engines is 70 m.p.h. Further particulars may be found on page 68 of the July, 1927, number of Baldwin's Locomotives.

Southwold Ry.  E.A. Phillipson. 271
Klapper's letter in the July issue makes it obvious that he and I are at cross purposes on some points, and I therefore venture finally to trespass on your space to clear up a few misunderstandings. In the first instance, I must admit I took it that Klapper advocated the operation of varied forms of prime mover. I am well aware that such a procedure is by no means without precedent on both light and main line railways; at the same time, I, personally, do not in general regard this as good practice when applied to a railway comparable in size with the, let us hope, merely temporarily defunct Southwold line.
In this particular case, I most certainly consider the operation of an independent locomotive, having a high speed engine with reduced drive, and working a light train with a considerably lower fuel consumption than would obtain with an engine of conventional form, to be easily within the capabilities of one engineman. The only proviso is that a "dead man's" regulator handle, or kindred safety device, must be fitted. The train staff would, of course, be limited to one conductor-guard.
As regards mixed trains, I am afraid financial considera- tions would render them an evil necessity. The evil would however, be to a certain extent mitigated in this particular instance, because:-
(1) "Bumping" is, unfortunately, inseparable from any form of combined central buffer coupling between engine and vehicles, although admittedly absent, of course, in the case of a rail car;
(2) Arrangements can easily be made whereby there is no necessity to shunt the passenger coaches when attaching wagons intermediately.
(3) Two or three additional minutes may be allowed conditionally on the running time for the last section of the trip, to be taken only when required to regain excess time at stations.
A mixed train, as I visualise it on a reorganised Southwold Ry., would, however, not be a very terrifying thing. I have repeatedly noticed that the bulk of the goods traffic is be- t ween the respective termini at Halesworth and Southwold, and that the intermediate stations contribute but an infinite- simal proportion to the total. Therefore, until the develop- ment of the latter type of traffic is fostered, incidental shunting will have little effect on train working. Further, the couplings and continuous brake would be standard on all stock, for both passenger and goods traffic.
The operation of the goods service with one daily train, as a separate entity, would be at a disadvantage in comparison with mixed working in that
(1) Delivery of freight would be retarded; delays are already sufficiently encouraged by transhipment. Also, more wagon stock would be required to transport a given quantity of goods. .
(2) With only one engine in steam, allowing for engme requirements and "running round" at termini, and assuming a permissible maximum speed of 25 m.p.h., the minimum interval between trains running in a given direction would be somewhat over the hour. The interruption caused by interspersing a goods working would therefore be a serious dislocation, The only alternative is to work the goods tram before or after the normal time the line is open to passenger traffic each day; this would involve extra expense in bringing station staff on duty solely to deal with the goods, which would be loaded or delivered at times inconvenient to the recipient or sender, as the case may be.
I quite see Mr. Klapper's point with regard to limitation of capital expenditure, and his remarks are most timely. I may say that I estimated, very roughly, the cost of merely relaying the existing location with heavier track and providing appropriate modern rolling stock on the lines I have advocated, and the total was truly astounding. At the same time, the additional capital which would be required for re-alignment would not be great, as the country is not difficult from an engineering point of view, and the concomitant earth works would not be extensive in consequence. The money would also be well spent because it would eliminate those places which form the present limitation of the maximum load any given locomotive is capable of handling, and also because additional traffic would be secured to the line by reason of greater convenience afforded to its patrons.
The suggested extension to Lowestoft is not only justifiable in that it would, in my opinion, of itself represent a profitable investment of capital, but also because it would strengthen the position of the existing system.

Soutluoold Ry. J.R. Belcher
Being interested in the closing of the above railway and in your esteemed correspondent, Mr. Phillipson's letter, I think he is painting too rosy a picture when he deals with the elaborate passenger stock suggested.
It should be patent that such stock is bound to be expensive to maintain for so small a company, and if he had read my letter in the East Anglian Daily Times of April 18, I think he would, like many others, have agreed with me.
To open out light railways to-day for passenger service is a serious problem even for main line companies, owing to the severe road competition. This sounded the death knell of the Southwold Ry., and to revise on such a scale as suggested would be hopeless.
My own idea for the benefit of Southwold is as follows, the main point is low capital outlay, at the same time low operating charges. The main point to bear in mind, if an attempt is being made to make the railway pay a dividend, is to relay it to standard gauge and run goods only, leaving passenger work alone, as it involves one's own stock and is too risky. Main line pattern sleepers, 56-lb. rails where necessary, and the formation strengthened where required, using the existing rails where possible.
One Sentinel locomotive would suffice to commence with, and as time went on could be added to by No. 2 Sentinel. This would be the only rolling stock the company would require of their own, as all goods and merchandise that comes to Southwold is through traffic from foreign lines, and the same thing applies to the reverse traffic.
I do not agree with your correspondent when he deals with the transhipment of goods, as it is a poor compromise and expensive in any form.
As stated above, the cheapest way out of the difficulty is to adopt standard gauge and cater for through traffic, and a dividend on the capital outlay should be certain if properiy managed and all overhead charges kept at the minimum.

Hadfields Ltd., East Hlecla and Hecla Works, Sheffield, 272
Leaflet of four pages describing their heat-resisting steels for boiler plants. Engineers have long recognised the advantages of high temperatures in steam operation. With the knowledge gained by past experience, temperatures will be raised still higher, improving efficiency and reducing sizes of plants. It is, however, unsafe to trust to ordinary steel for higher temperatures on account of risks of failure in respect of mechanical or other properties. Considerable research work has been carried out by the firm, and as a result two brands of heat-resisting steels have been evolved, known as "Era" and "Hecla.' The "Era" is used for turbine casing castings, forgings and valve bodies where ability to sustain stresses at high temperatures is required, not taking into account such considerations as resistance to corrosion or erosion of the steam. The "Hecla" brand is better suited for the flange bolts of steam pipe lines, and is chiefly used for components. For spindles and valve seatings where resistance to corrosion and erosion is of primary importance, their "Galahad" non-corrodible steel has many advantages.

United Strip and Bar Mills Ltd., Sheffield, a handy pocket-size booklet setting out the various sections of steel strip and bar they have available for their customers' use. Many useful tables are also incorporated. From the illustrations and description of this up-to-date plant, it would appear that it is one of the most advanced plants in the country for the continuous production of strip and bar steel.

Superheater Co., of New York,  272
Three booklets are to hand entitled A Short Story of the Locomotive Superheater, 1929 Locomotive Progress, and an Instruction Book on Elesco Locomotive Feed Water Heaters. The first- mentioned gives a brief history of the locomotive superheater and the efforts made to prevent initial condensation in steam cylinders. Attempts to stop this were made by James Watt, and although it is only within the last twenty-five years or so that superheating has come into vogue, the underlying principles were known long ago. In 1910 the Locomotive Superheater Co. (now the Superheater Co.) was formed, and the Elesco type A superheater (at that time known as the Schmidt) was fitted to eighteen 4-6-2 type locomotives for the Northern Pacific RR. Now more than 55,000 American-built locomotives are so equipped and in service. The Elesco feed-water heater reclaims as much of the heat in the exhaust steam as possible. This apparatus also pre-heats the boiler. feed water, and by so doing reduces fuel consumption. The book gives full instructions on the operation and maintenance of this heater.

Gartsherrie Ironworks and its locomotives. 363-4. 2 illustrations
William Baird & Co. Ltd. was formed in 1830 to develop iron smelting initially based on local iron and coal in the area around Gartsherrie. They constructed blast furnaces there and at Kilwinning, Lugar and Muirkirk in Ayrshire. The firm had running rights over both the LNER and LMS and ran trains from Gartsherrie to Kilsyth with its own 0-6-0 tender locomotive which was kept very clean and smart. It was built by Dubs & Co., in 1874 (No. 756) and was painted a very light green, with fine black panels and vermilion lining, it hads a brass dome casing and safety-valve cover, and copper chimney cap. The eighteen "pug" engines were distributed among the Company's plants and collieries at Gartsherrie, Bedlay, Twechar and Bothwell, and were of several makes: Nos. 2, 14 and 17 were by Peckett, of Bristol, dated 1918; 1890 (WN 489), and 1899 (WN 738) respectively. Nos. 3, 5, 6. 8, 11, 13 and 15 were Neilson engines, dated 1887 (WN 3629), 1889 (WN 3994), 1899 (WN 5566), 1901 (WN 5935), 1882 (WN 2937), 1876 (WN 2203), and 1894 (WN 4689). Nos. 4 and 21 were Barclay's: WN 236/1881 and 1512/1917 respectively. The North British Locomotive Co. Ltd., supplied Nos. 7 (WN 16732/1905), 18 (WN 17904/1907), 19 (WN 18385/1908), and 20 (WN 18386/1908). They were the standard Neilson design, but with slightly larger cylinders and tanks. Engine No. 9 was a veteran, built by Dick & Stevenson (their No. 16), dating back to 1867. No. 10 was built in 1919 by Grant, Ritchie & Co. (their No. 805). A second tender engine No. 12, almost identical with No. 1 was cut up in 1929. Former Nos. 2 and 10 were standard Neilson 0-6-0 saddle tanks (No. 1939 of 1874, and 2068 of 1875), withdrawn in 1916 and 1917 respectively. No. 16, which was sold prior to 1916, was built by Pecketts. The Company had other locomotives at the plants at Lugar, Muirkirk, Auchincruive and Kilwinning. Indebted to James Robertson, works manager, and John Mushet, chief engineer at Gartsherrie Works, for facilities for photographing Engine No. 1, and for most of the information in the above article.

"Three-decker" railway crossings. 365. illustration
Photograph shows the unique case of three main line railways crossing each other at different levels, near the Main Street (Union) Depot, at Richmond, Virginia., U.S.A. When the picture was taken, the lower train shown was standing on the single track of the old Richmond and Danville Railroad, which extended from Danville to Richmond and West Point, and was then included in the Southern Railroad system. The middle train was one of the Sea-Board Air Line, and it stands on a single line over a bridge built across the R. & D., some thirty years ago, when the railway was constructed through to Richmond. The uppermost train is one of the Chesapeake & Ohio Railroad, and this is seen running over the double-tracked viaduct, which had to be constructed to give that railway an uninterrupted road alongside the James River, from Hollywood Cemetery to Orleans Street, a considerable distance, which made it, for the time being, probably the longest steel viaduct in the world. The Chesapeake & Ohio and Seaboard trains, at the time, ran into the Main Street station, whilst the Southern trains used an old station on S. 14th Street ; all railways now use the Main Street (Union) Depot. Apart from the crossings of the various tube railways in London, the only similar instance we know of is at Chesterfield, where the former Manchester, Sheffield and Lincolnshire Ry. is crossed by the Midland main line as well as the former Lancashire, Derbyshire and East Coast Ry. The Lancashire, Derbyshire and East Coast Ry., which is now part of the Great Central section of the L. and N.E. Ry., commences at Chesterfield, which is approached by the viaduct shown in our second photograph, consisting of one span of steel girders, 115 ft., over the Midland line, and two spans of steel girders over the M.S. & L. Ry. The rest of the viaduct consists of seven brick arches, varying in span from 58 ft. to 30 ft. ; the height from the foundations to rail level is about 63 ft. At Charing Cross, London, the Underground tubes are below the District Ry., which, in turn, is underneath the Southern Ry. tracks, entering Charing Cross terminus, and also at Blackfriars, where the Southern Ry. crosses the District and the Waterloo and City (Tube) Ry. Immediately outside Liverpool Street terminus of the L. & N.E. Ry. at the Spitalfields goods depot is an instance of three tiers of lines, but only the lowest level is a main traffic line.

Robert Stephenson & Co. Ltd., Darlington. 366
Received an order from the Buenos Ayres and Pacific Ry. for twelve three-cylinder passenger tank locomotives of the 4-6-4 type with cylinders 19 in. dia. by 26 in. stroke, and were of a new design. It was estimated that the light weight would be about 94 tons, whilst the weight in working order would be about 120 tons.
For the San Paulo (Brazilian) Ry. they were to build two brake locomotives for the new "Serra" incline, of the 0-4-0 type; cylinders 13 in. by 16 in., fitted with special apparatus for rail gripping and rope nipping for controlling the trains on these inclines. The locomotives to be built under the inspection of Fox & Mayo, consulting engineers to the San Paulo (Brazilian) Ry. Co.

Concluded from page 289. Following WW1 and as soon as conditions appeared relatively normal, further engines of the Pacific type were ordered, but of different design to those built by Maffei. This series, Nos. 901 to 915, was built by the American Locomotive Co., and represented one of the first attempts of a Pacific engine with only two cylinders in Europe. No further description is necessary, as an illustrated article will be found in the October, 1920, issue of this journal.
