A pressure discharge railway hopper car includes a car body having a plurality of hoppers arranged in adjacent relation longitudinally, each opening at the bottom end to an aerator tub assembly. Each aerator tub assembly has two aerator units, one on each side laterally of the longitudinal centerline of the car body, defined by downwardly convergent inclined walls. An outlet from each aerator unit is connected to a product discharge conduit that leads substantially horizontally and laterally toward the centerline of the car body to a generally L-shaped discharge pipe. Each discharge pipe may include a longitudinal leg that runs between the two sections along the car centerline and a lateral leg extending transversely to the centerline to an outlet end laterally outwardly of the aerator tub assembly, where it is connected to a main discharge pipe.
