Abstract
A system to remotely report the load condition of a railroad car including a mechanism to sense the load condition in the form of a switch responsive to load condition to change the state of an electrical circuit, a controller to recognize the state of the circuit and a radio wave transmitter directed by the controller to report the condition to a remote receiver. Load is sensed by recognition of the distance between two components of the car, one which remains relatively fixed regardless of the weight of the car, the other which moves relative to the first component as the car weight changes.
