Abstract
A control system for an electrically-operated railroad car end door includes, an actuator, a processor, and a memory storing program instructions that cause the processor to instruct the actuator to begin generating a braking force applied to the railroad car end door in response to an opening of the railroad car end door, and determine whether the railroad car end door is being manually opened by a person based on information related to a state of the railroad car end door while the braking force is being generated.
