1. An automated terminal test system for conducting a terminal test of brake equipment on a train, such brake equipment being computer controlled and including a brake and a brake pipe;

  • said system comprising;

    (a) a test control box linkable to such computer controlled brake equipment of such train, said test control box having a control for activating said test control box and for applying and releasing such brake and for charging and venting such brake pipe upon appropriate manipulation;

    (b) an end of train transceiver means connected to such brake pipe on a last railcar of such train for monitoring pressure within such brake pipe on such last railcar and for sensing movement of such last railcar and for communicating signals representative of such pressure monitored and such movement sensed;

    (c) a head of train transceiver means linked to such computer controlled brake equipment and connected to such brake pipe on such head of train locomotive for monitoring pressure within such brake pipe on a head of train locomotive and for transmitting to such computer controlled brake equipment data pertaining to such pressure within such brake pipe on such head of train locomotive and for relaying to such computer controlled brake equipment data received from said end of train transceiver means pertaining to such pressure within such brake pipe on such last railcar and such movement of such last railcar; and

    (d) a display means connected to such computer controlled brake equipment for displaying a plurality of information including such brake pipe pressure data generated by said head of train and said end of train transceiver means, such last railcar motion data generated by said end of train transceiver means, an indication of activation of said brake release initiator of said end of train transceiver means, and a terminal test mode message when such computer controlled brake equipment is operated in a terminal test mode, such computer controlled brake equipment being in said terminal test mode upon activation of said test control box;

    wherein through such appropriate manipulation of said control, a railyard worker can apply and release such brake automatically and charge and vent such brake pipe automatically from outside such train.
