A New System Of Steam Heating adopted
On the Pennsylvania Railroad.


After two Years Of trials sui experiment.
the Pennsylvania Railroad Company la,
adopted system for heating the passenger
cars by steam. which experts declare IL be the
best, safest, AMI Surest mode oi heatIu. Vet
devised.
The Philadelphia Times oi March lith
thus DESERVES it -
The system Is what is known rs The CON
densatiou system. Two siriigh: lion pipes.
two inches in diameter. are placed under th,.
floor OF the car aud are connected nv cross
pipes in the centre y small pump : iaSten-
ed To one corner OF the tender and connected
with the boiler by pip. Tie STAN passes
through the pump. eIt. + one pipe and .s>t.s
through it Ia the centre of the Gar. Here ii
goes up through valve ami branches nf 'nt"
two iron pipa>. Tlr>r plp-> extend :tcru>-
the width of TIA. ear and ,rc met IAu long
wrought iron tubes runIIiu. irH.ihw!>,, %: The
car. From these pr =; a short spur PIPE an
der each sat. Tti. Steam GOES fIF'I.u Ines
pipes. passes up through ~" rt'litfn'> III each
end of the ear and Is tI"u drawn down
through CAS-. iron plpc back - III r'ulrs. at
the car. whert il pa>.,', through i wave and
enters The return pipe.
1.-The little pump Oh the t"uti'I ! constant
" at work and crsars Vacuum which
draws hack la the pump the condensed water
Ia ldilon 10 this the exhaust from the y imp
aud the air-brake are both directed into the
tank. The valve in The center vi the car is
so arranged that when the temperature Is high
enough. by turning small cock under the
centre seat the supply Of steam Is shIs; II from
that and it rushe> through The pip- IL the
next one. In this manner one car can be
without any heat while the Thermometer
climbs ~ i'll the uIn.-t., "a ~. .fl'f>. or
in the same manner one sid'I Of the car can
be heated TO higher temperature than the
other. il necessary. When the steam reaches
the crilire of the last car j, goes up through
the valve, enters the heating pipes AID rads-
tors and then is Caught By the vacuum and
drawn back TO its starting place.
GOOD VENTILATION AFFORDED.
NO steam escapes in any place and H..
pipes from the of I hc center of the last
car have no steam in them, while The car il
self is well warmed Is the pipes ON the inside
BY this means no dripping occurs and the
vacuum is 50 strong thai the Steam pipes are
entirely free from water and Ia tlst. event OF 4
wreck and the pipes wrr. broken I'll. Y tcium
is SO powerful h II It would suck lie air in in
| stead Of allowing the steam IL escape la
making up 4 train OF cars Ih. III. p,p.> under
the car iloor cunn.c;rd by meas Of a slip
| grip and about 4 foot OF strong rubber hose
| L nderneath each seat is hole two inches
wide bored through the floor OF the car In such
| a manner that when the cold air PUSHES i'll it
strikes the hot iron pipes ou the inside and he
| comes heated.
This arrangement keeps a constant cur
rent OF warm. fresh air in the cars AT all times
| and the vacuum in the pipes draws what little
| water there is III the pipes. 81 that when the
| cars are uncoupled there is no; ! drop nf wa
ter to fall On the road bed or station foor. 1t
requires but little steam Ia run Ia. pump arI
on yesterdays run from Philadelphia 10 New
| York. with a train of twelve ears. but live
| pounds of steam pressure WAS used. This
was sufficient 10 create vacuum in the re-
| turn pipe averaging fourteen inches. la the
! supply steam pipe il averaged SIX inches and
| on the engine nineteen IuciieS nr nine and
one-half pounds. the average temperature
during the run was >evcnty-;i:c degrees
| EXPERIMENTS WITH THE TEMPERATURES.
Several experiments made To find
| out how high the temperature could he raised
! In some of the cars the mercury registered
| ninety degrees and in others when the steam,
was shut off il dropped twenty and thirty
degrees. As the train went rushing along the
| wind came through the apcrlures in TIE floor
and purified what would otherwise have been
close atmosphere. The iron pipes are coy
cred with thin wooden She uhiue>. aud the
passenger who is troubled with cold feet can
warm his toes rs we'll as il he had them wrap
! ped up in hot-water bottles. TIN new system
works to perfection. and mot n hitch or break
has occurred To mar the per!ect success Of the
| system"
| By this method of heating every desirable
| point is gained 4 sufficient aiuoun, of heat
can always be SECURED, aud it can he regnlat-
| ed To any desired temperature There /, no
hot water in the pipes Ia scad OF barn in case
OF accident. and an ample supply of pure fresh
| AIR is supplied through the sp rtare> f.r ven.
| tilatiou.
| On the Introduction If this perfect system
| CT heating. the ear stove with all lis terrible
possibilities will be forever discarded The
oil lamp has already given Way 10 The electric
| light, aud with tie abandonment of the stove.
the last objectionable feature in railway travel
will be happily gotten rid nf w event in the
history of railroadiu. will serve Ia stimulate
travel SO greatly.
1t is expected tina, all of the PASSENGER ears
| of the Pennsylvania Il ,ilIold w;ll he fitted
with this appliance beioie arnthrr winter.
