The Worlds Two Largest Loco
motives Ready for Service.
VIII Be Put Into Use on the
Southern Pacific Lines.
LARGER FOR SANTA FE
This Road Has Ordered Four
Which Will Weigh 800 Tons.
Other Items of Interest in
Railway Circles.

Philadelphia, April PA pair of
giant freight locomotives, which not
only in size but strength eclipse any
heretofore built will be turned out this
week from the Baldwin Locomotive
works for the Southern Pacific railroad.
One of the two is to be placed on the
tracks of the Reading railway, opposite
the Baldwin works, one day this week,
and will remain until Saturday.
An idea of the superiority of these
locomotives over preceding types is
gained from the statement that each
weighs, including the tender. 100000
pounds, or 300 tons, and is tabulated to
do the work of three locomotives of the
ordinary consolidation type used on the
Pennsylvania railroad. Their power is
equal to that of two of the largest con-
solidation type of the Pennsylvania,
and they are each capable of haul
ing 10000 tons on a dead level
In other points than size and power
these new machines are a distinct adj
vance in locomotive building.
Larger Ones Planned.
But great as is this achievement, the
Baldwin works are already preparing
TO discount the new record, and will
shortly turn out four locomotives for
z the Atchison Topeka & Santa Fe rail-
) road that will be of 10 per cent greater
weight imam THESE Two, anu III WHICH

economic devices. Plans for these are
now being made. and they will be out
of the works by July.
A list of the dimensions of the two
new Southern Pacific locomotives will
give an idea of their immense size.
These are:

Contain New Devices.
The locomotives are of the Mallet
type: that is. they are virtually in two
parts. coupled together. This gives to
so long a mass of metal the play neces-
sary in rounding curves. The boiler is
affixed to the rear section only. In this
the locomotives are not new depar-
ture. 1t is in size, power and economic
features th2t they are notable.
One of the new features the device
for heating the water before 1t enters
the boilers Another is for the super
heating of the steam after it is eX-
hausted from one cylinder and before il
enters the other The 40-inch cylinders
are the largest ever used in a locomo-
tive of any type.
Santa Fe to Have New Ones.
The largest locomotives heretofore
built were turned out from the Ameri-
can Locomotive works for the Erie rail-
road. and weighed. including tender. 27(
tons These two weigh 300 tons each
while the four now building for the
Santa Fe-Two freight and two passen-
ger-will weigh 800 tons each
