UP EARLY CHALLENGER
 

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.
