A locking mechanism for releasably and positively locking a hinged door of a railroad hopper car in a releasably closed position or condition is disclosed. The locking mechanism for each hinged door on the hopper car includes a lock carried on the hopper car adjacent a discharge opening, a pivotal locking element carried by the discharge door and movable therewith into releasable but positive locking engagement with the lock when the door is swung into a closed position or condition, and a door release mechanism for controllably releasing the locking element from engagement with the lock thereby permitting the discharge door to swing to an open condition or position. When a series of doors are arranged in end-to end relation along a bottom of the car, the door release mechanisms for the discharge doors are operated substantially simultaneously thereby opening substantially an entire bottom of the hopper car. Furthermore disclosed is a discharge door design including top and bottom panels having a cavity therebetween extending across and along substantially the entire length of the discharge door.

[ What is claimed is:] [1.]1. A locking mechanism for a hinged door attached to a railroad hopper car such that said door moves outwardly from a closed position to an open position, said railroad hopper car having an underframe supported on wheels for movement over tracks, said hopper car further having a hopper supported on said underframe for holding particulate matter there within, said hopper defining a discharge opening relative to which said door moves between the open and the closed positions, said locking mechanism comprising:a lock carried by said underframe;a lock lever carried by said door for limited pivotal movement and movable into engagement with said lock to releasably hold and lock said door in the closed position; anda door release mechanism including an actuator rotatable about a fixed axis for urging said lock lever out of locked engagement with said lock thereby permitting said door to gravitationally move toward the open position from the closed position.
