The door operating system of the present invention can be applied to new railcar or retrofitted to existing railcar designs. The hopper car will have a pair of doors on opposed sides of the center sill which are connected through a door spreader. The pneumatic, individual door operating system is connected to the door spreader through an adjustable spreader fulcrum in which the sliding adjustment may add in a proper connection force or tension between the door operating system and the individual doors.
