He said that if express trains
profit, suitable engines must be
obtained. At present there are no suitable engines
for hauling the express trains. Sometime ago
Mr. Lao, the manager of the Chinese Section of the
Railway, Fr. Stratton, and Mr. Robert Baker, manager
of the British Section, had a discussion, and it as
considered that the best plan would be for the Hong Kong
Government to buy in the first instance a new
locomotive which the Canton Government could take
over on payment by instalments. There are two ways of
dealing with the matter: one is that the long Kong
Government buy the locomotives with power to run
them over the whole line; and the second is that
the Canton Government should buy the locomotives
and run them under the present working agreement. The Hong Kong Government has called for tenders
for one locomotive, which is estimated to cost about
MARSHAL LI says that he is very anxious to improve, not
only this line, but all the other railways in
Kongtung. There is profit in the undertaking if
the railways are properly run. The most important
problem is the labour problem, and it must first be
settled before there can be any hope of profit.
HIS EXCELIENCY says that something should be done no ".
R. FUNG CHUK-MAN
says that there is already a scheme
under consideration by the Commissioner of Reconstruc-
tion. By this scheme it is expected that the Kowloon-
Canton Railway will make about $10,000 a day instead
of $5,000.
LR. CHỦ suggests that the Hong Kong Government in the
first instance buy the locomotives, and the Canton
Government can afterwards take them over on payment.
HIS EXCELLENCY
answers that, in order to have the line run
profitably, at least thres engines should be purchased. The ones used at present are unsuitable. Tenders
for a suitable locomotive have already been called for.
but he can invite tenders for three, if arshal Li
so desires.
MARS AL LI requests His Excellency to proceed accordingly.
HIS EXCELLENCY desires to make it quite clear that the se
three engines, if first purchased by the Hong Kong
Government, must be token over by the Canton Government
as soon as that Government is in a position to do so.
MR. CHU says that he presumes that until then the engines
would be hired to the Canton Government.
HIS EXCELLENCY
agrees. The engines will be on hire, but
he would like to know whether the Canton Government
proposes to buy them eventually.
ER, CHU and R. FUNG CHUK-MAN
answer in the affirmative.
MARSHAL LI says that his Goverment would like to have
details before any tender is accepted.
HIS EXCELLENCY says that he will send a despatch to the
Canton Government setting forth the arrangements
proposed, and the Canton Government can then confirm
such arrangements in writing. As Marshal Li has
mentioned, the labour problem is important in
connection with the Railway, and he considers the wages paid in Canton too high: they are higher than
those paid by the British Section. If such high
rates continue to be paid, the line will never yield
a profit. Anot er problem is maintenance. The manager of the British Section has reported that
the engines and rolling-stock sent by the Chinese
Section to Hong Kong for repair, are generally not properly looked after, after they have been repaired..
As all good lines have a locomotive superintendent,
he suggests that one should be appointed for the
Chinese Section. By this appointment the repair
bill would be considerably reduced. The manager of
the British Section considers that there are Chinese
employed on the Chinese railways who would be quite
suitable for this post.
SIR SHOUSON CHOW says that, as far as he knows, there is
a locomotive superintendent on every other railway in

copy- not mall. to F.O.
With reference to paragraph 4 of Sir Cecil Clementi's secret despatch of 19th Lay, 1947, concerning the inauguration of a service of two express trains daily between Kowloon and Canton, I have the honour to inform you that the engines of the British section, not being designed for long-haul work at high speed, are not suitable for continued service of this nature and that the question of their replacement by specially designed engines now requires consideration.
While it is most desirable both for financial
and political reasons that this service should be maintained, I consider that this tovernment would not be justified in purchasing engines designed for a non-stop journey to canton which would be of no particular use to it shoulû fresh disturbances in Kuangtung again require the frontier to be made the terminus for British rolling stock. The Lanagement of the Chinese Section realises the validity of this argument but have unfortunately at the moment no surplus funds where- with to purchase on their own account nor any prospect of accumulating funds until they have completed the very extensive repairs required by their track and rolling stock. The latter

work is being carried out, by request, in our shops at reasonably remunerative rates and with the rent of our engines absorbs the Chinese Section's share of the traffic receipts taken at our terminus.
With a view, however, to being in a position
to place orders for new engines of the type required as soon as funds become available, the Chinese Section has requested that tenders may be invited in England forthwith at its expense. 1 accordingly enclose a specification together with an outline drawing for 4-6-0 Locomotives and would request that the Crown Agents may be referred to their letter 646
Enclo. No. 261/10 of 5th December, 1924, (copy enclosed) and asked to
obtain separate tenders for the building of one, two, and three engines. Delivery in the latter cases may be consecu- tive with a reasonable time limit.
As stated above the Chinese Section undertakes to refund to this Government all charges in connection with these tenders but it is presumed that the sum of £20. 18. 9 debited to this Colony in Crown Agents' account #261/10 of 27th February, 1925, will be deducted from any charges made for the preparation of drawings and specifications.
When the tenders have been received arrangements for the eventual purchase of the engines by the Chinese Section will be submitted for your approval.
I have the honour to be,
Your most obedient, humble servant,
M.D. Sou Shon.

given to the design so that the jet of steam is sufficiently
powerful to clear the ashes and that the fall of the
ashes from the smokebox bottom to the ejector is
facilitated by an easy sloping path. The steam jet nozzle
should be protected from becoming clogged up with falling
ashes, when not in use. The discharge pipe is to terminate
in a flange fitted with a hinged lid, wing-nut and bolt.
The steam jet is to be operated by a steam cock suitably
fitted on the firebox back plate.

not to obstruct unduly the driver's view. A Gresham &
Craven No. 10 Injector with "Simplex" cones is also to be
fitted under the foot-step on the right-hand side, all as shown on Drgs.Nos. 2.4472/61 /62 and /58, Reqn.No. 251/1.
The particular drawings in the "as made" sets relative
to the Pump and Heater are to show distinctly the fullest
particulars both in arrangement and detail for information and guidance in operation. To facilitate dealing with
the ordering of spare parts for the pump and heater installation, the whole of the component parts should be properly scheduled and named as shown on Drg. No.Z.4472/ 62A, Regn. No. 251/1.

Jestminster,
London, S...1,
5th December, 192.
I have the honour to refer to your letter No.1270/
1924, dated 23rd August, in regard to the proposed new
coaches and engines for the Kowloon Canton Railway.
2. As requested we have discussed the question of the
design of the new stock with the Chief Mechanical Engineer,
Dr. Lambert, and have prepared a preliminary design and
detail specification of the proposed engines, copies of
which have been handed to r. Lambert. We have also prepared
a draft specification for the rolling stock but we propose
to wait until the design of the stock on order under Indent
No.106, dated 19th March, has been finally approved before
sending you copies of the designs and specification. We may
state, however, that the designs generally are well advanced,
and we are now in a position to invite tenders for locomotive or rolling stock on receipt of an indent.
3. We should like to place on record our obligations
to Mr. Lambert for the considerable amount of time he has
devoted to this matter and for the assistance he has so
kindly rendered.
The Colonial Secretary,
Fong Kong.
I have, &c,
(Sd.) F. G. Bradstreet,
for Crown Agents.
