  • Charging cut-off valve arrangement for microprocessor-based electropneumatic locomotive brake control system
    Patent number: 5332297
    Abstract: A microprocessor-based locomotive brake control system having an electropneumatic brake pipe pressure regulating circuit via which a train brake pipe pressure is controlled and a normally closed charging cut-off valve between the brake pipe regulating circuit anad the brake pipe. The charging cut-off valve is electropneumatically controlled in order to effect opening of the normally closed charging cut-off valve on a controlling locomotive. An arrangement is provided for maintaining the charging cut-off valve open when electric power is lost on a controlling locomotive, while providing for closure of the charging cut-off valve on a non-controlling locomotive irrespective of the presence or absence of electric power.
