Nickel Plate Road Offset Hopper #33074 As early as the late 1920s, the American Association of Railroads began designing standardized 50-ton open hopper cars. These hoppers would ride the rails for decades. The A.A.R. standard 50-ton open hopper was classified HM, which designated it as a self-clearing open top car with two divided hoppers, fixed ends, fixed sides and doors hinged crosswise to allow dumping between the rails. The cars became widespread on coal hauling railroads throughout the country, seeing service behind steam and diesel locomotives. In the tradition of the Lionel PS-1 boxcars, the scale-sized, metal Lionel Offset Hoppers include many separately applied details and, for a more prototypical look, ride on accurately detailed trucks without a hanging "trigger disc."
