A hopper car discharge section may be wide at the top and narrow at the bottom. Outflow is controlled by closure members, at least one of which is movable. The closure members come together to a closed condition or position for retaining lading. When apart, in an open position or condition, lading may be discharged. A seal member or seal member assembly is mounted to one or both of the closure members. When open, the seal member or seal member assembly lies substantially flush with, or shy of, the slope of the surface of the closure member. When closed, the seal member may be self-energizing, in the sense that as lading is added the seal may tend to seal more tightly. The seal assembly may include a cantilevered spring that presents a land to the opposed closure member, and a fulcrum, over, or across, which the spring is cantilevered, such that pushing down on one end of the spring may tend to cause the other end to flex upward. The fulcrum may also be cantilevered outward from the slope sheet of the closure member to which the seal assembly is attached. The discharge section may be robustly reinforced to discourage deformation.
