Abstract
An actuating system for manually operating the doors of a railroad hopper car. An operating shaft having a handle is rigidly coupled to an actuating lever. A door opening lever, which is rotatably coupled to the actuating lever, is rotatably coupled to the door for a hopper chute. To operate the system, an operator rotates the handle of the operating shaft, rotating the actuating lever and the door opening lever, shifting the door from the closed to the open position.
