A railroad maintenance device distributes, regulates and reclaims ballast along a railway road bed. The device includes one or more hopper cars for transporting and depositing ballast, a regulating car including a track regulator, a shoulder regulator, and an extensible plow arm for reclaiming ballast deposited at a distance from the shoulder of the road bed. The hopper cars include radio controlled gates for the remote control of ballast depositing operations, and a computer controlled system for optimizing the distribution of ballast according to predetermined parameters. A bucket elevator is located rearwardly of the track regulator for lifting excess ballast from the road bed, and a belt conveyor transports the lifted ballast to a hopper car. |
