Revell of Germany 2165 1/87 Big Boy Locomotive 4-8-8-4 RVL02165 Plastic Model Kit. During the late thirties Union Pacific often used auxiliary engines to haul trains from Ogden, Utah up a steep pass to Wasatch. The American Big Boys are some of the longest and largest steam locomotives ever built anywhere in the world. Union Pacific wished to simplify this system and instructed their own development department to design a new locomotive capable of hauling a 3,600 ton train (max 4,200 tons) up the steep pass. The 25 Big Boy locomotives were built in 2 groups. The first group, called the Class 1, was built from 1941. The second, Class 2, was built in 1944. Most Big Boys were retired from service in 1961. The last goods train was hauled by a Big Boy loco in July 1959. Model kit: one piece boiler reproduction, detailed driver's cab, separate butterfly damper, skill level 4, movable pony trucks, front cow catcher, detailed driving wheels, detailed tender with ladders, decals for 2 union pacific versions, and finely detailed reproduction tracks measuring approximately 48 cm.
