Abstract
A mechanism for selectively operating hopper doors of a railroad car. A fulcrum coupled to the operating cylinder includes channels within which levers can be selectively activated to open specific doors of the car, thus allowing the contents of the railcar to be sequentially emptied. The mechanism can be installed on railcars having either transverse hopper doors or longitudinal hopper doors.
