Abstract

See full text

A manual discharge door operating system for a hopper railcar includes a door actuation shaft coupled to the railcar extending across the width of the railcar. The door actuation shaft has distal ends accessible from opposite sides of the railcar with each distal end adapted to be engaged with a handle for rotation of the actuation shaft by the operator. Rotation of the actuation shaft opens and closes the discharge door of the hopper railcar through linkage assemblies. Preferably, a door operating linkage assembly is provided with an over-center closed position to hold the door in the closed position.
