freight car
railroad car designed to carry cargo. Early freight cars were made largely of wood. All-steel cars were introduced by about 1896 and within 30 years had almost completely replaced the wooden variety. Modern freight cars vary widely in shape and size, but virtually all of them evolved from three basic types that had been in use since the early 1800s: the open-top car, the boxcar, and the flatcar.
