DYNAMIC RAILROAD FREIGHT CAR MONITORING SYSTEM

The patent relates to a monitoring system that provides an engineer of a freight train with a real time picture of the coupling extensions of selected cars distributed throughout the entire length of his train. Located between each selected pair of cars is a sensor that detects whether a Buff (compressed) or a Draft (stretched) condition exists at the coupling. Individual encoders associated with each of the sensors respond thereto by providing one of two uniquely coded outputs representing, respectively, either a Draft or Buff condition as detected by the sensor. The outputs of the encoders are relayed by individual transmitters to a receiver located at a control station. Coupled to the receiver is a decoder that decodes the incoming signals and energizes a display that furnishes the engineer with a dynamic indication of the coupling condition existing at each of the selected points along the train.
