Abstract
A servo that is attachabley secured to the rail car frame at each door lock that is connected to the latch via a draw bar with sufficient modulus to withstand the repeated force required to move the latch thus opening the door. The servo provides a pulling action with the motive force being pneumatic pressure but not limited to pneumatic whereas hydraulic or electric energy can be supplied to the servo providing the motive force to pull the draw bar attached to the latch, that when said servo provides a pulling force sufficient to over come the friction ot the latch to the striker plate the latch moves in a upward direction thus releasing the door to open. A second element of the servo is to provide a pushing action via the draw bar to the door latch to drive it all the way into the closed position.
