Hopper cars have been used by railways worldwide whenever automated cargo handling has been desired. This type of car is distinguished from a gondola car in that it has opening doors on the underside or on the sides to discharge its cargo. The offset-side 4-bay hopper represented by our model was an outgrowth of earlier 2-bay designs, and could discharge its load faster due to the 4 doors underneath.
