A large capacity car body for a pressure discharge railway hopper car has a plurality of end slope plates assemblies, each having a slope sheet; and a plurality of intermediate slope sheet units, each of inverted "V" shape. The intermediate slope sheet units and the end slope plates form the end walls of a plurality of hoppers. A crossridge frame is associated with each of the intermediate slope sheet units and together with the end frames supports side sheets and a top sheet. Top chord members and bottom chord members extend coextensively with and are welded to upper and lower edge portions of each side sheet. Edge portions of the top sheet overlap and are welded to upper leg portions of the two top chord members. The crossridge frames and chord members considerably increase the resistance of the side sheets and top sheet to deforming when the car body is pressurized during unloading. The sides and the top of the of the car body are curved in end profile, the sides having radii of about eleven feet and the top a radius of about seven feet. The overall width of the car is about ten feet, eight inches, and the top sheet has a span of about eight feet, five inches. The curvatures of the side and top sheets and the overall dimensions provide the car body with added capacity in the upper and lower corners, as compared with a car body having a substantially circular cylindrical end profile.
