FOR RAILWAY SAFETY

= OR about two years system % sI,,o-
matte train control has been I'm i-.. .,
portion Of the lines of the North
Stanordshire Railway Company. rr
England. The officials of the corrtrv
were so pleased with the efficiency of he
system that they determined recently to
test 1t in larger way by placing IL In SEP
vice at one OF their most important june
ton points where the traffic is unusually
heavy. Representatives Of several of ne
leading railways in England were present
at this test, and expressed great sat.srac-
ton with the result Whenever II is pru-
dent, on account Of a dangerous curve. such
as caused the recent disaster at nury
or for any other reason. to permanently
reduce the speed OF trains, II is ClaIm,d
that this can be automatically accom-
pished so that the safety OF passengers
viii not be jeopardized ny careless or eek
less engine drivers The following de.orip-
ton OF the invention was published y the
Liverpool Post and Mercury
THE system, of which Mr.. Thomas z.
Raymond Phillips. of Liverpool, Is the In
iventor, is remarkable for its ingenuity and
simplicity. It's most commencing merit
is its reliability.
For long time system OF signalling
has been almost universally in use which
repeats In the signal cabin the condition OF
the signals which are controlled from mat
cabin. SO many signals are not visible
Grated that the value OF this safeguard ~
quite obvious. The Raymond Phillips In
ventIon carries this principle a fur her
stage, and achieves an even more notable
and important precaution by repeating the
state of the signals not only In The signal
box. but also in the cab OF the locomotive,
and so insures that the driver shall all
times have a clear View OF the condition ~
/ the signals governing the road over which
his engine is to run. This is accomplished
by means OF pneumatically operated MINI
Iiature semaphores fitted up in the ca or
the locomotive. Opposite each line 81 nal
a set OF 'trippers' in duplicate Is placed In
the four foot way. The tr1ppers are me-
chanICally and electrically connected with
the ordinary signalling apparatus, and
stand erect or lie nat according as the sig
nails show danger or line clear
Beneath the locomotive there are 'wo
striking levers, moving either way, VIII n

trippers when they. are erect and TO J. -

cred When danger IS slgnal,ed, tn 80

effect that the semaphOres in the cab Z
the engine faithfully reproduce the sign l.
and the lovers, after striking the trpper-
remain securely locked until released by
the driver. But that Is not all. Should
