Abstract: A system includes a drive system having one or more traction motors coupled in driving relationship to a plurality of wheels of a vehicle system. The traction motors are configured to provide both motive power for the vehicle system in a propel mode of operation and retarding effort to brake the vehicle system in a braking mode of operation. The system further includes a parking brake for maintaining a static position of the vehicle system when in an engaged state, and a controller configured to detect when the parking brake is in the engaged state. The controller is further configured to control at least one of the one or more traction motors to provide a braking effort to resist movement of the vehicle system when the parking brake is in the engaged state.

Abstract: Systems and methods of the invention relate to diagnosing a compressor. A method may include monitoring a pressure of compressed air within a reservoir, actuating a piston within a cylinder of the compressor, and detecting a leak condition of an exhaust valve of the cylinder through recognition of a change in the monitored pressure of the compressed air within the reservoir during a time period in which the piston is actuated. A system is also disclosed including an engine, a compressor operatively connected to the engine, and a controller that is operable to determine a condition of the compressor.

Abstract: Various methods and systems are provided for detecting a change in turbocharger performance. In one example, a method comprises determining a level of turbocharger imbalance based on output from a turbine speed sensor and generating a signal related to a change in a performance level of the turbocharger if the level of turbocharger imbalance is greater than a threshold.

Abstract: An apparatus for lifting and moving an axle of a rail vehicle includes a frame, a pair of rollers rotatably mounted to the frame to movably support the frame on a railroad track rail, and a pair of wedges mounted to the frame having mutually opposed ramped faces. The pair of wedges adjustable along the frame between a first position in which the ramped faces bracket, but do not contact, a rail vehicle wheel that rests on the track rail, and a second position in which the ramped faces engage the circumference of the wheel to support the wheel at a height above the railroad track rail. The apparatus further includes at least one jacking device for urging the wedges toward one another from the first position to the second position.

Abstract: A system includes a location determining circuit configured to acquire position information of a vehicle system moving along a route. The system also includes a controller circuit having one or more processors. The controller circuit is configured to calculate curvatures of the route, based at least in part on the position information, to form a curvature waveform. The controller circuit is further configured to generate a route map based on the curvature waveform.

Abstract: A system includes a sensor and a controller. The sensor is configured to detect sliding of a wheel of a vehicle. The controller is configured to communicate with the sensor and a traction motor operatively connected to the wheel such that the traction motor selectively applies forces in at least one direction to the wheel during operation. The controller is further configured to direct the traction motor to apply a motoring slide reducing force to the wheel when the sensor detects sliding of the wheel resulting from a frictional braking force.

Abstract: Methods and systems detect short circuits in an electrical system, such as a dynamic braking grid of a vehicle. The methods and system measure a characteristic of a current that is conducted through one or more resistive elements of an electrical system. The current is supplied to the electrical system from a power source as an applied voltage. A resistance change signal representative of a change in one or more electrical resistances of the one or more resistive elements is determined The resistance change signal can be based at least in part on a difference between the characteristic of the current that is measured and a low pass filtered value of one or more of the characteristic of the current that is measured or the applied voltage supplied by the power source. A short circuit event is identified based at least in part on the resistance change signal.

Abstract: A system includes a grid coupled to an electrical bus; an electrical power modulation device coupled to the electrical bus that can output modified electrical power received from the electrical bus; a blower motor coupled to the electrical power modulation device that can receive the modified electrical power output and can provide a stream of air to affect a temperature of the grid, and a controller. A speed of the blower motor may be based at least in part on an amount of the modified electrical power. The controller can receive an operating parameter, and is responsive to that parameter by causing the electrical power modulation device to vary the amount of the modified electrical power. A blower motor speed may be controlled based at least in part on the operating parameter.
