Abstract
A bottom discharge hopper rail car has a hopper body mounted on a chassis which is itself supported on flanged wheels. The body has a pair of downwardly converging, laterally spaced side walls with longitudinally extending lower edges which border a discharge opening. The spacing between the lower edges of the sidewalls is greater than the lateral distance between the wheels as wider openings can facilitate discharge. In practice, the wheels have outer flange surfaces adjacent to rail-engaging surfaces for resting on the rails, and the spacing between the lower edges of the side walls is preferably greater than the distance between these outer flange surfaces. The side walls are asymmetrical with respect to a longitudinal vertical plane passing centrally between the wheels as this can inhibit bridging during discharge. A door is pivotally mounted on the body and displaceable between a position in which it closes said opening and a position in which it is spaced from said opening to permit discharge of the contents of said body.
