2-10-0 Decapods were not a favorite with most railroads; they were rough-riding,
but the Pennsylvania Railroad was satisfied with what they saw. The Decapods
were tough, had enormous strength, and could be depended on for carrying
goods up large mountain slopes. It was said that wherever there were hills,
there were usually decapods not far away.
The first Altoona-built 2-10-0 locomotive emerged from Juniata's erecting
shop in December of 1916. It was designed by the genius of Alfred W Gibbs
and Axel S Vogt. The I-1 engine could travel up the Allegheny Mountains
of Pennsylvania faster than other engines in use built prior to this one.
A total of 598 I-1s were built. 123 I-1s were built at the Juniata Shops
and 475 at the Baldwin Shops. The order for 475 at the Baldwin Shops was
the largest order ever for a single class of power!
By 1924, I1s were tearing up the railways. They were regarded as the standard
heavy freight hauler of the railroad, achieving speeds of up to 50 miles
per hour. They replaced three smaller types of engines: the Consolidations,
Mikados, and USRA Santa Fe's.
Some specifications of the I-1 included a boiler that was the largest
applied to any Pennsylvania Railroad class up to 1916. The boiler was
fed by mechanical stokers and required 250 pounds of steam pressure in
its 30 1/2" x 32" cylinders to operate. The total engine weight
was 386,100 pounds and had tractive force of 90,024 pounds.
The first I-1, Locomotive No. 790 displayed Juniata Shop badge plate No.
3165. It out-performed the L-1 class 2-8-2 by forty-one percent more horsepower,
while utilizing twelve percent less steam. It could travel great distance,
powered by only a small amount of steam.
Over a span of many years, the I-1 engines were broken down into subdivisions:
the I-1sa and Class I-1s. The I-1sa class had 489 locomotives and the
I-1s class had 109 locomotives.
The most notable feature of the decapods was the twin bulky air reservior
tanks riding up front on the pilot deck. They were not on the original
locos, but were implemented later.
One of the last and most famous runs of the I-1s was the transporting
of iron ore out of Northumberland, Pennsylvania. They carried nine thousand
tons of ore over the Shamokin Branch to an interchange in the Lehigh Valley.
