ABSTRACT:
A ballast hopper car door control apparatus and method for controlling a pivoting hopper discharge control member on a railroad ballast car or the like, includes a drive shaft extending through the discharge control member at the pivot point. A transmission is connected to the drive shaft and is driven by a reversible electric motor. The motor is controlled via a radio receiver which receives motor control signals from a remote radio transmitter. When there are a plurality of ballast cars on a train, each car has a receiver which responds to a different address sequence. The remote transmitter is operable to selectively send any of the different address sequences so that a single selected car can be remotely controlled. Multiple hoppers on a single car are controllable by a single receiver.
