The American Big Boys are some of the longest and largest steam locomotives ever built anywhere in the world. During the late thirties Union Pacific often used auxiliary engines to haul trains from Ogden, Utah up a steep pass to Wasatch. 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 up the steep pass. The last goods train hauled by a Big Boy loco was in July 1959. Most Big Boys were retired from service in 1961. Model details: Model with internal fittings; Removable roof; Two variants can be built; Filigree front grab handles in two versions; True-to-original reproduction of pivoted bogies, can be turned and removed; Transparent parts; and Filigree reproduction of roof ventilators.
