A system for controlling movement of a passenger train having a locomotive and a plurality of doors is provided. The system includes a door status sensor to determine open and closed status of each door of the locomotive. The system further includes a first control module coupled to the door status sensor and a relay coil through a first diode. The relay coil is energized on receipt of input from the door status sensor, when all doors of the locomotive are closed, and the energized relay coil allows controlling movement of the locomotive. The system further includes a door override switch. In an actuated condition, the door override switch allows power to flow from a power source to the relay coil, thereby energizing the relay coil. The energized relay coil allows controlling movement of the locomotive.
