  • Patent number: 8010246
    Abstract: The present locomotive brake control system includes a vacuum relay valve responsive to air brake apply and release signals on the air brake pipe to provide vacuum brake apply and release signals on a vacuum brake pipe. A locomotive brake controller is responsive to the brake apply and release signals on the air brake pipe to control the brake cylinder to apply and release the locomotive brakes in an air mode, and is responsive to the brake apply and release signals on the vacuum brake pipe sensed by a transducer to control the brake cylinder to apply and release the locomotive brakes in a vacuum mode.
    Type: Grant
    Filed: February 14, 2008
    Date of Patent: August 30, 2011
    Assignee: New York Air Brake Corporation

  • Patent number: 7340329
    Abstract: A control system and method which includes storing the geographic location of the neutral sections along the path onboard the vehicle. A GPS system on the vehicle determines the geographic location of the vehicle. A program of the control system determines the position of the vehicle relative to the position of the neutral section from memory using the GPS to determine the location of the vehicle. Next, it provides a control for maintaining the circuit breaker of the vehicle open as the source collector passes through the neutral section.

  • Publication number: 20050125112
    Abstract: A method of determining the configuration of locomotives in wired distributed trains. It includes determining consists of adjacent locomotives in the train. It determines one or more sub-consists of adjacent locomotives, which are controlled separately from a preceding adjacent locomotive within the consist. Locomotives which have an available wired distributed power controller is determined. A common consist indicator is assigned to all adjacent locomotives of a consist if the consist has at least one available wired distributed power controller. A common sub-consist indicator is assigned to all locomotives of a sub-consist if the consist has at least one available wired distributed power controller.

  • Patent number: 6626034
    Abstract: The method includes reducing pressure of a charged brake pipe to a predetermined pressure value. The brake pipe is then charged only from the head end unit. Each intermediate brake pipe monitoring and charging device sequentially reports on the network a pressure which is an increase if the brake pipe is continuous between it and the head end unit. Subsequent to receipt of a report of an increased pressure on the network from an intermediate unit, the head end unit commands that intermediate unit to participate in charging the brake pipe. The head end unit determines the brake pipe continuity from the pressure increases reported by the intermediate units.
