ABSTRACT:
A door locking arrangement for a railway car hopper includes a latch element and keeper assembly having camming surfaces which during gravitational opening of the door lift the latch element to a disengaged position. The locking is controlled by a longitudinal actuating bar which controls the latch element. A spring biasing device urges the latch element to its locked position.
