An actuating system for operating transverse doors of a railroad hopper car. The mechanism includes an operating member which is coupled to a door or doors of the car by a shaft and a linkage which couples a power source to the operating member, where the operating member rotates to move the door away from the hopper. The mechanism can operate doors which open in opposed direction with a single power source. The mechanism can be used in new car construction, and can be retrofitted onto existing hopper cars.
