A mechanism for operating one or more hinged doors on a hopper car including an elongated operating shaft having a fixed axis of rotation and a linkage system for operably connecting the operating shaft to the hinged doors on the railroad hopper car. The linkage system includes an actuating link operably connected to and rotatable with the operating shaft and a connecting link for operably connecting the actuating link to each door. The linkage system links includes a primary lock for holding each door in the closed position. A selectively operated secondary lock is rotatable about a fixed axis disposed above the fixed axis of the operating shaft assembly. The secondary lock rotates between a first condition, wherein a stop engages with at least one link of the linkage assembly, and a second condition, wherein each door is permitted to move to the open position. A release mechanism is provided for releasing the primary lock by moving at least one of the links of the linkage system relative to the other thereby allowing the door to be forcibly moved toward their open position under the influence of the columnar load being placed thereon by the lading in the hopper.
