Abstract

According to some embodiments, a discharge door locking system for a railcar discharge door comprises a lock piston configured to move between a first position (not engaged with an operating beam coupled to a discharge door) and a second position (engaged). The locking system comprises a first and second input. Activation of the first input moves the lock piston to the first position, and activation of the second input moves the lock piston to the second position. The first input of the locking system is coupled to a first input of an operating cylinder coupled to the operating beam. The first input of the operating cylinder is configured to move the discharge door to the open position.
