Abstract
A high volume covered railway hopper car is disclosed which has vertical end walls so as to fully utilize the space over the trucks of the car for lading volume. An automatic pneumatic unloading system is provided so as to unload a pulverant lading from the end compartments or hoppers, as well as the center, of the car, thus eliminating the necessity of sloped end sheets. A pneumatic loading system is provided which permits loading from below and thus permits the elimination of hatches, walkways, and the like on the roof of the car so as to permit the roof to extend substantially the full extent of AAR height clearances thereby to further maximize the lading volume of the car.
