which is Expected 10 Make 100 miles an
Hour
The Pennsylvania Railroad company
under the direction of Mr.. Theodore N
ELY, general superintendent of motive
power, has just completed, at its great
SHOPS at Altoona, what is in many re-
spects the most remarkable locomotive
ever constructed, and, II the capabilities
OF this splendid machine prove to he
what is expected Of Ii. there will be
most Important departures made by the
company IN the construction of passen-
ger engines Intended for hauling heavy
fast express trains.
The great size Of the engine can be
pictured from the following description
Total weight of the machine alone is
l40,OOO pounds, or seventy-tvo and one
half tons. When complete with the ten
der and ready for service, combined
weight OF all is 224,0O0 pounds or III
tons, There has never been locomo-
tive constructed on four drivers which
y as heavy as this one, there being 40
900 pounds over each pair of drivers.
The driving wheels are the largest
ever built for locomotives in this country
and are seven feet, or eighty-four inch
es,. in diameter. The boiler pressure is
200 pounds, and the compound prin-
ciple is of the two-cylinder type. The
two-hundred.po und-pressure has already
been maintained with surprising ease on
the trials.
The cylinders are respectively nine
teen and a half and thirty-four inches
in diameter, the high pressure-cylinder
of course, being the smaller, and the low
pressure the biggest locomotive cylinder
ever constructed. The pistons Of both
cylinders have twcnty-eight-inch
stroke; and among the many advantages
possessed by the engine Is one enabling
the engineer to start the train with
steam from the low-pressure cylinder.
The high-pressure cylinder is on the left
side of the train and steam generated
passes first through it, exhausts into the
low-presure cylinder and is then blown
off
The boiler is six feet in diameter and
twenty-seyen feet long. The fire box is
as large in proportion, being ninG
feet long, and forty inches wide,
inside CRATE measurement. The height
to the top OF cab fourteen feet,
to the top of the stack, fifteen
feet, the distance from the bot.
tom Of the boiler to the rail IL six
and half feet so tina man over six
feet tall could walk under tie
boiler. In the construction of locomO
tives the slide valves are usually placed
on top of the cylinder. In this engine
valves twelve and q half inches In di
ameter. The forward wheels are forty
two inches In diameter, and are stee
tired, with wrought iron centers.
The tender is equipped with three
pairs of wheels, instead of eight wheels
on two trucks. They are of the same
pattern as the forward wheels of the
engine. and each pair is equipped with
equalized brakes. The tender is equip
Dedwith sDring buffers
The idea is to get the time between
Jersey City and Philadelphia down "a
ninety minutes, maintained schedule
speed of sixty miles an hour. This il
is desired to do with the new locomotive
under all conditions, no matter how un.
favorable, taking consideration of de-
lays, slow running stretches, etc. This,
of course, requires that the engine shall
make up time lost, and bring the train
over the road at an average Of mile a
minute, including everything, IL is
hoped that under the best conditions,
after the engine is thoroughly in trim,
that as high Il speed as 100 miles an
hour may be maintained.
