Which Il Expected to Make 100 Mncs an
fsour.
The Pennsylvania railroad company
under the direction OF Mr.. Theodore
n. Ely general superintendent o.
motive power has completed ut its
great shops ut Altoona what Is iu
locomotive ever constructed aad il
the capabilities OF this splendid ma
chine prove 10 be what is expected Of
it there will be most important de-
par,ures made by the construction OF
passenger engines intended FOR haul
ing heavy fast express trains
The great size OF the engine can be
pictured from the following descrip-
ton; Total weight OF the machine
alone is l45, 900 pounds or seventy
two and one half toas When com
plete with the tender and ready for
service combined weight of all is
224 900 pounds or il2 tons There
has never been locomotive con-
structed on four drivers which Is as
heavy as this one there being -
600 pounds over each pair of drivers
The driving wheels are the largest
ever built for locomotives in thus
countrT. and are seven feet or eighty
four inches in diameter. The boiler
pressure is 800 pounds and the com
pound principle is OF tho two cylinlor
type The two-hundred- pound pres
sure has already been maintained
with surprising ease OF the Ir ais
The cylinders are respectively nine
teen and half and thirty four inches
in diameter the high pressure cy!in-
der OF course being the smaller and
the low pressure the biggest locomo-
tive cylinder ever constructed The
pistons of both cylinders have a
twenty-iuch stroke. and among the
many advantages possessed by the en-
gine is one enabling the engineer TO
start the train with steam from tho
low pressure cylinder. Tho high.
pressure cylinder is on the left side Of
the train. and steam generated passes
first through it exhausis into the low
pressure cylinder aad is then blown
OF.
The boiler-s six feet in diameter
aud twenty seven feet long The fire
box is as large in proportion being
nine feet long and forty inches wide,
| inside CRATE measurement The height
to the top OF the cab Is fourteen feet;
| 10 the top OF the stack fifteen feet;
the distance from the bottom OF tho
boiler to the rail is six and half feet
so that man over six feet tall could
walk under the boiler. In the con-
structIou OF locomotives the 81 dc
valves are usually placed on top Of the
cylinder In this engine they are be-
tween them. aud are piston valves
twelve and hall inches in diameter.
| The forward wheels are ioriy-two
| inches in diameter and are steel
tired with wrought iron ceuters
| The tender Is equipped with three
pairs OF wheels instead o! eight
wheels on two trucks They are OF
tho same pattern as the forward
wheels OF the enigma and eAch pair
is equipped with equa ized brakes.
The tender is equipped with spr.ns
! buffers
The idea is to get the time between
Jersey City and Philadelphia down TO
ninety minutes snys the Cincinnati
Enquirer maintained schedule speed
| OF 81 ty miles an hour. This il Is de-
sired to do with the new locomotive
under all cond lions no matter RoH
uniayoraole taking considerations OF
delays slow running stretches c.
This Of course requires that the en-
giue shall make up time lost and
bring the train over the road at an
average o! mile . minute inc'uliug
everything, II is hoped that under
the best conditions after the engine il
thoroughly in trim that as high a
speed as 100 miles an hour may be
maintained
