ABSTRACT:
A railway hopper car includes laterally positioned bottom dump discharge openings and doors which are locked in a closed position by a latching mechanism actuated from a ground-mounted trip lever. After the car has been dumped it is moved adjacent to a ground-mounted cam which is engaged by cam followers on the doors thereby swinging the doors again to the closed position.
