This BLI model is of the Class CSA-2 Challenger, commonly called an "early challenger".  This model has a post-1947 appearance, after the locomotives were renumbered from 3900 to 3800 series. 

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.
