Abstract
A rapid discharge railcar door consisted of a plastic main body reinforced by an aluminum frame, and which provides sufficient strength against load-bearing forces and withstands changes in temperature. The main body of the door is made from a polymer in a reaction injection molding process. The door reduces the overall weight of the railway car, thus allowing more coal to be shipped per car.
