THE CROYDON ATMOSPHERIC

RAILWAY.

The following is the report of Mr. Samuda, presented
to the last meeting of the London and Croydon proprie-
tors, relative to the progress of the atmospheric system
on the line :
" I have the honour to report to your board the pro-
gress of the atmospheric works on your line.
" From the Forest- hill Station toi Croydon the atmos-
pheric apparatus is laid, the engine fixed, and experi-
mental trains have been run.

" As far as relates to this portion of the line, it now
only remains to complete the station arrangements, get
the engines into proper working order, and instruct and
practice the telegraph men and train conductors in their
respective duties, to enable it to be opened for public
traffic.

" The whole number of atmospheric pipes intended
for the New Cross line are prepared and ready to be laid,
so soon as the road is sufficiently advanced to receive
them ; the rest of the atmospheric apparatus belonging
to them is on the ground, and this portion can be eom-
pleted within one month after the road is ready.
" Atmospheric tubes and apparatus are in course of
preparation for the other portions of the line, so as to
enable us to follow up the earthwork and ballasting in all
cases without delay.
" The result of the experimental workings has been in
every respect successful, and has realised in the fullest
degree all that was expected.
" A speed of seventy miles per hour has been attained
with a train of six carriages ; a speed of thirty miles per
hour with a train of sixteen carriages.
" Using only one steam-engine over two sections of
main (a length of five miles) we have found it practi
cable to attain a vacuum of more than twenty-seven
inches in the whole length. And we have both ex-
hausted the main and run trains at a very high speed
(upwards of sixty miles an hour) over the five miles with
the aid of one engine only.
" When exhausting the main with the engines, as in
tended in practice,-working vacuums have been attained
within the time calculated.

" We find the arrangements well suited for working
the intermediate stations traffic.

"Some slight delays have arisen from the improve-
ments in, and novelty of, many of the parts introduced in
this the first single line of railway which works both
ways on the atmospheric principle, rendering additions
and variations necessary, which have only been shown
to be advisable in the course of the experiments alluded
to, but the whole are now in course of satisfactory com-
pletion. " J. D'A. SAMUDA."
