Product Information:
The Union Pacific Challengers were simple articulated 4-6-6-4 steam locomotives built by American Locomotive Company for the Union Pacific. Union Pacific built 105 of these locomotives between 1936 and 1943. The Challengers were 122 ft (37 m) long, weighed 284,800 kg, and operated over most of the Union Pacific system, primarily in freight service. The excellent Challenger design allowed for increased speed on mountain grades compared to UP's previous articulated steam locomotives.
