ABSTRACT:
A railway hopper car having bottom dump discharge openings include a bell crank arm which is pivoted by a camming arrangement positioned adjacent to track to an opened position whereby a load is discharged. An auxiliary latch is provided which in the normal operating condition of the train locks the arm against rotation to prevent opening of the doors. The camming device includes an arrangement which is first engaged by an auxiliary latching element which is moved to a release position whereby a cam follower engages the camming face of a cam to thereby pivot the bell crank to its open position.
