Union Pacific 4014 is a steam locomotive owned and operated by the Union Pacific (UP) as part of its heritage fleet. It is a four-cylinder simple articulated 4-8-8-4 "Big Boy" type built in 1941 by the American Locomotive Company (ALCO) at its Schenectady Locomotive Works. It was assigned to haul heavy freight trains in the Wasatch mountain range. The locomotive was retired from revenue service in 1959 and was donated to the Railway & Locomotive Historical Society; thereafter, it was displayed in Fairplex at the RailGiants Train Museum in Pomona, California.
