The real "Big Boy" locomotive was built by the American Locomotive Company. It was classified as a 4-8-8-4 wheel arrangement, meaning that it had 4 guide wheels, two sets of 8 driver wheels and 4 trailing wheels. The "Big Boy" is the largest steam powered locomotive ever built. It was operated by the Union Pacific Railroad Company. There were 25 of these locomotives built and they were in operation from 1941 till 1959.
