Abstract
A hopper car in which the body has vertical end walls and side walls each comprising a sloping lower portion and a vertical upper portion. The two sloping lower portions converge downwardly and their horizontal lower edges define a discharge opening. One of these edges lies in a horizontal plane which is at a different level to the plane containing the other lower edge. The angle of slope of one lower portion is different to the angle of slope of the other lower portion. Additionally, the horizontal plane containing the line of convergence between the one lower portion and its associated upper portion lies in a different horizontal plane to the corresponding line of convergence of the other side wall. An arcuate door carrying a laterally protruding operating arm closes-off the discharge opening.
