Abstract
An actuating system for operating longitudinal doors of a railroad hopper car. The mechanism includes an operating member which is coupled to each end of the door set of the car by a shaft and a linkage which couples a power source to the operating member, where the operating members rotate to move the doors away from the hopper. Reversing the rotation of the operating members closes the door set of the hopper. The mechanism can be used in new car construction, and can also be retrofitted onto existing hopper cars.
