Systems and methods for powered rail car doors are disclosed. In one embodiment, a system includes a first door assembly operable to at least partially cover an opening of a rail car. The system also includes an actuator. A first common linkage is coupled to the actuator and is operable to reciprocally move in a longitudinal direction relative to the actuator. In particular embodiments, a first secondary linkage is coupled to the first common linkage and is coupled to an exterior surface of the first door assembly, wherein the first secondary linkage cooperates with the first common linkage to move the first door assembly between an open position and a closed position over the top hatch of the rail car. |
