A locomotive control system includes an operation manager controller electrically coupled to an operator controller of a locomotive and to a local vehicle control system of the locomotive. The operation manager controller receives an operator command from the operator controller and can regulate the operator command to control operation of the locomotive.

Vehicle operation control system

A vehicle control system includes an operation manager controller electrically coupled to an operator controller of a vehicle and to a local vehicle control system of the vehicle. The operation manager controller receives an operator command from the operator controller and can regulate the operator command to control operation of the vehicle.

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.
