The Union Pacific Challengers were a type of simple articulated
4-6-6-4 steam locomotive built by American Locomotive Company for the
Union Pacific. 105 of these locomotives were built between 1936 and 1943.
The Challengers were about 122 ft (37 m) long and weighed 284,800 kg.
Primarily in freight service, they operated over most of the Union Pacific
system. A few were assigned to passenger trains operating through mountain
territory to California and Oregon. The locomotives were built
specifically for UP and much of the experience gained later went into the
design of the famous Big Boy.
The name Challenger was given to steam locomotives with a
4-6-6-4 wheel arrangement. This means that they have four wheels in the
leading pilot truck, which helps guide the locomotive into curves, two
sets of six driving wheels, and finally four trailing wheels, which
support the rear of the engine and its massive firebox. Each set of six
driving wheels is driven by two steam cylinders. In essence, the result is
two engines under one boiler. The Union Pacific Railroad sponsored
development of this type to meet the need for higher speeds in main-line
service. Historically, articulated locomotives had been limited to slow
speeds by factors inherent in their design. The technical breakthroughs
achieved with the Challenger enabled the carrier to develop the Big Boy
with the same speed expectations. Speeds in excess of 60 M.P.H., while
unheard-of on other railroads using articulated steam locomotives, became
commonplace on the Union Pacific.
