Abstract
A hopper car discharge section may be wide at the top and narrow at the bottom. Outflow is controlled by movable closure members. The hopper car has a plurality of hoppers of which two hoppers share a common ridge assembly. The ridge assembly forms a common mating and fit up location for the upper margins of the slope sheets of two lengthwise adjacent hoppers. The ridge assembly includes an horizontal center section and two end plates that angle upwardly outboard toward the top chords of the sidewalls. The ridge assembly stands proud of the upper margin of the respective adjacent slope sheets. A gusset is mounted between the adjacent slope sheets below the ridge plate such that the slope sheets and gusset form a reinforcement tube running across the car, the end plates forming the stems of a vertical T-section attached to the sidewall and overlapping the top chord.
