ABSTRACT:
A locking arrangement for the side dump doors of a hopper car includes a pair of actuating levers projecting downward from the car engaging suitable trips mounted adjacent to the tracks which provides for longitudinal movement of a pair of latch bars which disengage a plurality of latches longitudinally disposed on the car between the hopper slope sheets and the swinging doors. Safety locks are provided to provide inadvertent opening of the latch mechanisms.
