THE BIGGEST LOCOMOTIVE.
A ISO-TON FREIGHTER BUILT
ron THE SANTA FIX ROAD.

OF Niagara There Are some worlds
Record-BreaklnE Points About II.
The worlds biggest and most powerful
locomotive, an American compound built
at Schenectady by the American Iocomo-
tive Company, Is on its way from abe Mo.
hawk Valley to the Far West. where 1t will
haul heavy freight on the Santa Pc road.
II represents the highest achievement in
locomotive design, the most notable effort
Of American builders TO produces an engine
Of enormous ~tractive power adapted ia
the needs OF our transcontinental lines
As a bold venture In massivcness, 9So's
service tests in the mountains OF the trans
missouri viii attract the attention Of the
railway engineers Of the world The
builders Of England and the Continent
| judged us insane when We passed the
| hundred-ton mark but here Is a monster,
weighing, without the fifty-ton tender,
| 1870 to~ns-twenty-one times a. much az the
| historic De Witt Clinton.
From the end OF the tender to the point
| of the pilot, this giant Of the rails measures
| seventy feet. Two engines OF 9s9's type,
II they could be suspended in the air one
| above the other, would reach a height
nearly as high at Niagara.
The top OF the stunted snok estack 10
| sixteen feet above the ties, and to such q
| height does the dome reach that its top
| had to be taken OF before the locomotive
could pass in safety under the overhead
bridges between Schenectady and Buralo.
The massive boiler IL perched 80 high in
the air that a tall man can stand under il.
But while the dome top Is thirteen feet
above the driving wheel axles, the centre
OF gravity Is very low inches
below the top line Of the drivers. The
engine gets its great stability from It's
massive frames, cylinder castings, driving
wheels and driving mechanism.
On a level track $50 could haul a train
a mile and a half long, carrying the har-
vest Of 10000 acres Of wheat, It's tracuye
power is $500 pounds, that Is, II could liit
this amount of dead weight,
H. great wheel base gives $50 this worlds
record hauling power. Ten massive drlv-
ing wheels, nearly as tall as a man, and so
heavily counter balanced that they appear
almost SOLID, grip twenty feet OF track,
On these ten drivers. which gave the
name Of decapod 20 this type OF engine,
a weight of 1924 O0 pounds IL carried. In
pony truck carries only fourteen tons,
much of the weight Of the saddle and cylln-
der castings being distributed over the
drivers by the equalizer beams so dlstfnc-
tive Of American design.
To make use of this unprecedented driv-
ing weight Of IFS tons, 9s9 must produoe
steam a. no other engine ever has. FOL
lowing the growing practice among the
railways of the Southwest. the Santa Fs
will burn oil ia this, its best engine. 49,.
It's frebox is made of carbon steel tested
to a tensile strength Of $1,000 pounds u the

shells are held together by nearly, POGO
tough s%taybolts, each one capable ofInung
a yard engine without breaking
The CRATE area IL sixty square ieet WHICH
il unapproachcd IN any other locomotive
ever built. The bottom Of the iirebOS
reaches out over tine tops of the drneFs
after the fashion of recent American ioco-
motives.
