Union Pacific No. 3910 (1936)

Union Pacific No. 3710 was a 4-6-6-4 "Challenger" type steam locomotive, built by the American Locomotive Company in 1936 for the Union Pacific Railroad and originally #3910 and later to #3810.
It was used for freight service on the Union Pacific Railroad, but it was occasionally used on passenger service as well.
