    摘要： A system is provided for pacing a powered system traveling along a route separated into a plurality of block regions. Each block region has a respective signal. The system includes a controller configured to receive a status of the signal in an adjacent block region to a current block region of the powered system. The controller is configured to determine a time duration between a change in the status of the signal in an adjacent block region. The controller is further configured to determine an expected status of the signal to be experienced by the powered system in the plurality of block regions, based upon the time duration and a route parameter of the plurality of block regions.

    摘要： A method and system is provided for detecting and performing diagnostics regarding an incipient ground fault that may occur in an electrical propulsion system of a traction vehicle, such as a locomotive, transit vehicle, or off-highway vehicle. The method allows providing a first ground connection for the electrical propulsion system. This first ground connection forms a grounding path generally used by the electrical propulsion system during normal operation. The method further allows providing a second ground connection for the electrical propulsion system. This second ground connection forms a grounding path selectively usable in lieu of the first ground connection. A control strategy is defined for switching between the first ground connection and the second ground connection. A respective leakage current associated with at least one of the first and second ground connections may be monitored. Switching between the first and second ground connections may be controlled based on the monitored leakage current associated with at least one of the first and second ground connections.

    摘要： A system and method for modification of a baseline ballast arrangement of a locomotive having an overall tractive effort rating based on symmetrical distribution of weight and driving torque applied by the locomotive to the respective axles of the locomotive. The system includes a locomotive truck comprising an un-powered first axle and a powered second axle. The system also includes a first suspension assembly configured to apply to the first axle a first portion of a locomotive weight and a second suspension assembly configured to apply to the second axle a second portion of the locomotive weight different from the first portion. An amount of locomotive weight allocated from the first axle to the second axle allows modification of a baseline ballast arrangement by reducing an amount of ballast in the baseline ballast arrangement corresponding to the amount of weight allocated from the first axle to the second axle.

    摘要： A kit and method for reconfiguring an electrical braking system for a traction vehicle are provided. The kit may include a braking system assembly including a chopper having a first chopper circuit topology. The first chopper circuit topology includes a first semiconductor-based circuitry having a footprint that defines at least one cavity in an enclosure for accommodating the first semiconductor-based circuitry. This enclosure constitutes the enclosure for accommodating the semiconductor-based circuitry in the chopper having electromechanical-based circuitry and semiconductor based circuitry. A second semiconductor-based circuitry is arranged in the at least one cavity in the enclosure for accommodating the first semiconductor-based circuitry. The second semiconductor-based circuitry when electrically coupled to the first semiconductor-based circuitry produces a chopper comprising a second chopper circuit topology fully contained in the enclosure. The second chopper circuit topology is operable without any electromechanical-based circuitry.

    摘要： A method for controlling a wheel speed of a locomotive includes determining an estimated wheel speed (52) for a desired wheel set of a locomotive responsive to a locomotive operating parameter indicative of an actual wheel speed of the desired wheel set. The method also includes generating a first adjustment parameter (e.g., 46) based on an operating condition of the locomotive, and then applying the first adjustment parameter to the estimated wheel speed for generating a first adjusted estimated wheel speed signal (54) used as a first input for controlling a wheel speed of at least one of the desired wheel set and the other wheel sets of the locomotive.
