A ballast distributing railroad car has a number of ballast hoppers, each with a selectively operable hopper door. The railroad car also has a pair of ballast distributing blades pivotally attached beneath it, one at either end of the car, with the blades being mirror images of each other. Each blade can be selectively raised and lowered via an independent hydraulic actuator. A remote control radio transmitter and car mounted receiver provide for remote, individual and selective control of hopper doors and blades on a car. 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. In a modified arrangement, each ballast distributing blade has a pair of extendable wings on either side to allow the wider distribution of ballast where needed. The wings are operated via individual hydraulic actuators which are also selectively controllable via the remote transmitter.
A hopper door and distributing blade control apparatus for controlling one or more of a plurality of hopper doors and one or more ballast distributing blades on a railroad hopper car, comprising:
On a train including a plurality of railroad cars, each car including a plurality of hopper discharge openings, each with a hopper door, and at least one ballast distributing blade attached beneath the car, said blade being movable between a non-operative position and an operative position, a hopper door and blade control apparatus for controlling said doors and said blade, said apparatus comprising:
A method of selectively, independently and individually controlling a plurality of hopper doors and one or more ballast distributing blades on a railroad hopper car, each said door being selectively movable between an open and a closed position, and each said blade being movable between an operative and a non-operative position, the method comprising the steps of:
In a railroad hopper car equipped for operation on a pair of railroad rails, said car including at least one material containing hopper, each hopper including a hopper door for dropping material in the hopper beneath the railroad car, the improvement comprising:
In a railroad hopper car equipped for operation on a pair of railroad rails, said car including at least one material containing hopper, each hopper including a hopper door for dropping material in the hopper beneath the railroad car, each said hopper door including a door operating means, the improvement comprising:
