Abstract

See full text

A system and method for operating a ballast car hopper door includes logic and control circuitry, a hydraulic actuator, a door position sensor, and one or more sensors operable to measure system operational parameters. During normal operation of the hopper door the logic and control circuitry records the system operational parameters. In the event of failure, or absence, of the door position sensor the control circuitry compares real-time data to recorded data to maintain operation and correct positioning of the hopper door.
