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.

A GPS controlled multiple source material application or ballast spreading system includes tracking the position of a plurality of ballast hopper cars using GPS derived coordinates and controlling the opening of multiple ballast doors to spread ballast on desired sections of track for railroad maintenance. The process involves tracking the current hopper loads, the opened or closed state of the ballast doors, and the concurrent amount of ballast which has been spread on the desired track sections.
