Abstract: A locomotive control system includes a locomotive having a traction motor and sensors. The traction motor provides tractive effort for propelling the locomotive and the sensors measure performance conditions of the locomotive. The system also includes a controller having one or more processors communicatively coupled with the traction motor. The controller selects one or more baseline conditions that designate operational conditions under which the locomotive is to operate, and monitors the performance conditions that are generated by the locomotive during operation of the locomotive according to the operational conditions designated by the one or more baseline conditions. The controller identifies a flashover condition or a plugging condition of the locomotive by comparing the performance conditions that are generated by the locomotive during operation of the locomotive with the one or more baseline conditions. The flashover condition or the plugging condition causing degradation of one or more components of the locomotive.

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 method for assembling a sensor assembly includes providing a sensing device configured to measure at least one variable. The method also includes at least partially enclosing a magnetic material within an enclosure. At least a portion of the enclosure is manufactured from a material having a permeability that facilitates forming a magnetic field therein. The method also includes coupling the sensing device to a first portion of the enclosure. The enclosure includes at least one second portion that is movable with respect to the first portion of the enclosure such that a magnetic coupling force is induced external to the enclosure to facilitate coupling the sensor assembly to a magnetic surface.

Abstract: A flow sensor assembly is provided and includes a flow conduit configured to impart a disturbance to a flow, multiple sensors disposed at respective sensing locations along the flow conduit. Each sensor is responsive to the disturbance of the flow and generates a corresponding response signal. The flow sensor assembly further includes a processor operably connected to each sensor, the processor being configured to compute a cross-correlation function between the response signals generated by said sensors, and determine a flow rate and a direction for the flow through the conduit based on the computed cross-correlation function. Additional flow sensor assembly arrangements are also disclosed.

Abstract: A locomotive control system measures actuating parameters of a locomotive propulsion system and monitors the actuating parameters according to a forcing function of operation of the propulsion system. A degraded component of the locomotive is identified by comparing actuating parameters generated according to the forcing function with actuating parameters expressed as a function of speed of another locomotive propulsion system, examining changes in the generated actuating parameters over time, examining oscillations in movement of the locomotive during gear shifting, comparing wheel speed decreases during another forcing function, and/or comparing a magnitude of a spectrum of the actuating parameters of with one or more designated magnitudes.
