Revell Big Boy Locomotive

The American Big Boys are among the longest and largest series steam locomotives ever built in the world. During the late 1930s, Union Pacific often used auxiliary locomotives to pull trains from Ogden, Utah to Wasatch over a steep pass. UP wanted to simplify this system and asked its own development department to design a new locomotive that could pull a 3,600 t train (up to 4,200 t) up the steep pass. The 25 Big Boy locomotives were built in 2 groups. The first group, called Class 1, was built from 1941. The second group (class 2) was built in 1944. The last freight train transport that was handled by a Big Boy locomotive took place in July 1959. Most of the Big Boys were decommissioned in 1961.
