Twenty-five Big Boys were built exclusively for Union Pacific Railroad, the first of which was delivered in 1941. The locomotives were 132 feet long and weighed 1.2 million pounds. Because of their great length, the frames of the Big Boys were "hinged," or articulated, to allow them to negotiate curves.

Union Pacific 4014 is a preserved 4884-1 class 4-8-8-4 "Big Boy" type steam locomotive owned and operated by the Union Pacific (UP) as part of its heritage fleet. Built in November 1941 by American Locomotive Company (ALCO) in Schenectady, New York, it was assigned to haul heavy freight trains in the Wasatch mountain range.
