The maintenance of the electric rolling stock of the Central Argentine Railway.
9-45. Disc.: 45-60.
Members of South American Centre met at Tigre, Argentina, on Friday,
29 September 1922. Author was Resident Engineer of Electrification, Central
Argentine Railway,. M r . A W. Bannantyne, Chief Mechanical Engineer, Buenos
Aires Western Railway, and Vice-Chairman of the South American Centre, presided.
Subsequently a visit was made to the car shed and workshop for the electric
stock. The Chairman said: I am glad that the electrified service on the Retiro
to Tigre via Victoria branch of the Central Argentine Railway was inaugurated
on the 25 August 1916. Since then the service had operated with complete
success, both from an engineering and a traffic point of view. The increase
in the number of passengers carried had been gratifying, as will be seen
from the following figures, especially when it is remembered that during
the past few years building, due to the price of materials, had been far
below normal for the suburbs of Buenos Aires

Extraordinary General Meeting was held at the Engineers’ Club,
Coventry Street, London, on Thursday, the 23 November 1922, at 7 p.m. The
chair uas taken by Colonel Kitson Clark in the absence of the President,
who wrote regretting that he was unable to be present on such an important
occasiori.
South African transport problems are governed by:
(a) Small population in relation to area.
(b) Great distances between:
(i) Chief industrial centres and coast;
(ii) Principal centres of population
(iii) Producing and consuming areas.
(c) Albsence of navigable waterways or canals.
(d) Vast tracts of undeveloped territory which railways must traverse to
reach their objectives.
The railways of the Union of South Africa were, with a few exceptiona, owned
and worked by a Department of State known as the Railways and Harbours
Administration.

Second Ordinary Genera1 Meeting (1922-23 Session) of the Scottish
Centre held in the Royal Technical College, George Street, Glasgow, on Friday,

Engineer, North British Railway) occupying the chair.
The loss of the Nord Co.’s main locomotive shops at Lille, besides many
of their large sheds and repair shops near the Belgian border, was a very
serious handicap; they also, of course, had to give up a large number of
their staff for military service. The main locomotive shops were transferred
to Amiens, which in peace time was a large district shop; they also managed
to arrange repair shops in the Paris district.
There mas considerable difficulty in obtaining a suitable site for the new
shops, but after many places had been reconnoitred and after many conferences
with the French it was eventually decided on 28 January 1917, that the British
Army should take oker the unfinished portions of the new shops of the Etat-Ouest
Rly., at St. Etienne du Rouvray a village about three miles from Rouen on
the main line to Paris, and about one mile from the old Etat-Ouest shops
at Sotteville. This line was the first railnay built in France, and much
of the original works remained a t Sotteville.
Nevertheless, it would appear at first glance that this site was too removed
from ihe traffic area operated by the British Army, but there were three
very good points in its favour :
Firstly: It was a good distance from the fighting area — Borre was in
a very unsafe position, as was proved later, and the possibility of having
to evacuate St. Etienne was almost as remote as that of losing the war.
Secondly: It was in a good position for one of the main base ports, le Havre,
where there were ample facilities for unloading heavy machinery, such as
locomotives, and at the same time there was a reasonably good railway connection
with the north-east. There was also a very good connection with Paris and
the south-west for such ports as St. Nazaire, if required.
1hirdly: Work had been commenced, practically all foundations were in, some
of the structural steel work was already erected and the rest was on the
site. Overhead cranes were also on order and were due for delivery.
On page 123 there is a list of all the locomotives used by the British
Expeditionary Force between 1917 and 1919; this includes locomotives from
the Caledonian, GCR (0-6-0 and 0-8-0 as well as WD 2-8-0); GER; GNR; GWR;
LYR; LBSCR; LNWR; Midland; NBR; NER and SECR.

Third Ordinary General Meeting (1922-23 Session) of the Manchester
Centre was held at the College of Technology, Manchester, on Friday, 1st
December, 1922, Mr. W. Rowland being in the chair.
Inside and outside cylinder designs. Discussion: W.G.P. Maclure (151) considered
that the objection to outside cylinders, so far as the riding of an engine
is concerned, was influenced by a certain amount of prejudice, the general
design of the engine having a great deal more to do with the riding. It must
be admitted that the liability for condensation in the case of the outside
cylinder is greater, and there is often some difficulty with regard to smokebox
joints being kept tight; but this, I think, takes place more particularly
when the cylinders are fastened on to the frames instead of being built up
with a centre portion to form one complete unit. J. Parry (151-2) noted outside
cylinders obviated the use of crank axles, and little can be said that is
good about a crank axle. The rolling of outside cylinder engines is sometimes
aggravated by the use of short connecting rods. The GCR engines, which Mr.
Maclure had experienced all had very long connecting rods. Rolling could
be reduced by using stiff bearing springs and making up for the consequent
reduced longitudinal flexibility by compensatitlg beams. It is much more
difficult to counterbalance the effects of reciprocating parts in an outside
cylinder engine than those of an inside cylinder engine; but with six or
more coupled wheels and a long wheel base, very good results can be obtained.
Many outside cylinder engines suffer through want of rigidity at the front
end, resulting in the failure of pipes, or at least theii joints. This fault
had been met by rigidly connecting the cylinders together, as Mr. Maclure
intimated.

G.W. Selby (623-4) commented upon LNWR practice.
The former North Western Railway had six mechanical coaling plants running
of various types. Crewe North was the first, and was the only one similar
in principle to the Trafford plant, although not so up-to-date. There were
a lot of points embodied in the Trafford plant which were great improvements
on Crewe North. They have a tippler discharging into an underground hopper
that holds about 20 tons, from which there is a bucket conveyor. The buckets
held about a third of a ton each, and emptied only when an engine was being
coaled: when an engine came under the shoot the bucket conveyor was started
and the number of bucketfuls discharged into the tender counted. That worked
quite well and was fairly simple.
It had been suggested that one might have a high ramp and simply empty the
coal right out. At Edge Hill there was a set of sidings about 30 to 40 feet
above the track, and a branch was simply turned out of the sidings and a
ferro-concrete bunker made underneath. Of course, that is the simplest possible
way; there is nothing mechanical about it; one simply ran the wagon over
the top and emptiede coal into the engines below.
The latest plant was Crewe South, and that is one where the wagon was lifted
and tipped. which Selbie consideredto be the simplest and most satisfactory
way, provided the bunker is not more than 400 tons. The Crewe South plant
had these advantages: firstly, no underground bunker; there was no excavation
work, and there was no necessity to keep a pump running to drain the underground
bunker of water; secondly, only one lifting motor and only one set of mechanical
work was involved, in place of having a tippler with an electric motor driving
it, a distributor below the floor level, a rotating disc to draw the coal
from the bottom of the .underground bunker and turn it on to the elevator;
then a third motor driving the elevator, making three electric motors and
three sets of mechanism at least-possibly a small electric motor for driving
the pumps as well. The combined horse-powers of these motors were generally
more than needed to lift the wagon. When the wagon is taken up on lift, the
weight of the lift, of the empty wagon :iud half the probable charge, was
counter-balanced. Carlisle and Camden had no overhead bunkers. balanced,
so that all the electric motor had to do is to lift half the charge. It took
just under two minutes at Crewe to raise the wagon and empty it, and just
under two minutes to come back. In four minutes from the time the wagon was
run on the table it could be emptied and back again ; that wagon's contents
were now in the overhead bunker and there was nothing more to do: one man
could look after it. One man and one shunter in the period during which bunkers
were being filled, and one man only on the other tmo shifts where coal is
simply being fed out of the bunker on to thc engines, are amply \ufficient,
and I do not think that can be done with any other form of conveyor.
As regards measuring the coal, I think as a rule the main question for a
railway company is whether they are getting the full amount of coal frotn
the colliery that they are paying for; that seems to be the most important
thing. Whether one engine is burning more than another does not matter exactly,
unless tests are being carried out. The principle we propose to h a w in
our next plant is to put '1 weighing machine in the base of the lift, and
as the nagon comes into the lift it registers its weight, so that there ;s
no waste of time at all.
I think the Crewe North plant has a calibrating arrangement, but I am not
sure about the others ; some of them have calibrating arrangements and sonic
have not. The point is that if the calibrating arrangements prokided could
be guaranteed to actually measure the coal exactly, it would be perhaps worth
while having them ; but they cannot bc relied on. We hale not tried an
overturning scale arrangement, as has been suggested; I have never seen that
applied to a locomotive coaling plant. The proposal i\ to open a valve and
fill a i t h coal a box that is supposed !o hold ten hundrednzight; then
the valve is shut and t h e contents of the box shot into the tender; this
operation i \ repeated a number of times, so that it takes about three to
five minutes to coal an engine. By simply opening a vaI\rs and alloming the
coal to shoot out on to the tender, thr" coaling is done in half a minute.
Because the engine Sot six half-ton reservoirfuls it does not necessarily
follow that it rereived three tons of coal, unless it was all small coal.
Another point about the Crewe South plant is in reg;ird to dust. Everyone
finds the Yame difficulty with the mechanical coaling plant ; there comes
a time u hen it di+ charges a tenderful of dust. This has been graduall\
gathering together, and then it comes all a t once. At Crcne South it was
found that there was one discharging shoot that generally turned the dust
out. It happened in that plant to be directly under where the wagon tipped,
and apparently the dust got straight down to the bottom and rhe big coal
rolled down the slopes. A spout was put under that and it was used for coaling
saddle tank engines.
The Chairman: A question has been raised as to whether hopper wagons were
used.
Mr. Selbie: Any kind of wagon would do as long as its .sides were not less
than a €not or eighteen inches high, and ilot niore than ten feet total
height. The plant we are considcring now will handlc anything from the smallest
se\ enton coal wagon to our large standard locomotive coal wagons, which
carry 20 tons comfortably. They are Ioft. high from the rail, 8ft. wide and
24ft. long, with a 12ft. wheelbase. An important practical point is to make
the rlebator long enough to take the wheelbase of the largest aagon. I know
a plant that has been put up with provision for only a nine-feet wheelbase.
As regards oil coming out of the axleboxes, if the wagon i, run on, emptied
and brought back immediately, there will not be much trouble. But if the
wagon is not absolutely emptied \\hen tipped, and the hopper only holds about
twcnty tons, it is very much iriclined to jam ; the hopper is completely
filled and thc tippler cannot be brought back, and the wagon may stand for
five or ten minutes. That does :;he the oil time to come out.

Carriage bogie design. 632-95. Disc.: 695-716, 1924, 14,
614-626.?????
Bogies of lighter design, supporting equal weights, had been in use
for oxer thirty years on steam stock and showed no signs of fracture; in
fact, there were many bogies in use without headstocks which gave no such
trouble. There may, however, have been other causes for fractures. It could
be deduced that no pressed member for bogie framing for electric coaching
stock should be less than ½in. thick and that means should be adopted
to keep the frame rigid.

The railways of Chile. 633-716.
The Chilian State Railways form three principal systems:
Arica to La Paz System.
Northern System.
Southern System.
The Arica to La Paz System in its Chilian section, has 206 km. of metre gauge.
It is administered directly by the Government of Chile, which appoints a
General Manager who is over both the Chilian and Bolivian sections.
The Northern System has 1,726 km. of metre gauge and will shortly have 2,439
km. when the 713 km. now operated temporarily by " The Chilian Northern Railway
'' have been handed over.
The Southern System has 2,635 km. of 1.676 m. gauge and comprises the lines
from Valparaiso to Santiago and Puerto Montt.
Both systems, the North and the South, constitute the Company of t h e S
t a t e Railways, a powerful autonomous corporation which is administered,
according to the 1914 law, by an Administrative Council of six members, two
of them being nominated by the President of the Republic, two by the Chamber
of Senators, and two by the Chamber of Deputies. The Council is presided
over by the Director- General of the Company, who is nominated by the President
of the Republic. The Members of Council nominated by the President of the
Republic hold office for five years, those nominated by Congress three years,
and the Director-General six years.

The subject was then complex due to conflicting opinions and tentative
theories inseparable from a comparatively new field of investigation, but
there had emerged certain accepted proofs, The Paper is divided into two
sections in an endeavour to separate and simplify branches of study which
differ substantially from one another, while both are essential to an
understanding of failures under repeated stress. Part I. is an account of
the machines used in endurance testing and of the results obtained for various
grades of steel. Part II. is intended as an introduction to the study of
the inner structure of metals and its influence on their endurance.
