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. 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.
Speeds in excess of 60 M. While unheard-of on other railroads using articulated steam locomotives, became commonplace on the Union Pacific. When moving forward from a stopped position, toots twice.
