Abstract: A system may include a processor to receive vehicle data from a vehicle system at a first location and communicate the data to a second location. The processor may integrate the data into a database of diagnostic data at the second location and identify a diagnostic code that indicates an expected operation of the vehicle system or an unexpected operation. The processor may determine a maintenance operation based on the diagnostic code. A method may include receiving vehicle data from a vehicle system at a first location and communicating the vehicle data to a second location. The method may include integrating the vehicle data into a database of first diagnostic data and identifying a diagnostic code that indicates whether the vehicle data represents an expected operation of the vehicle system or an unexpected operation of the vehicle system. The method may include determining a maintenance operation based on the code.

Abstract: An inspection system includes sensors that are selectively coupled to a vehicle during an inspection and/or maintenance event for the vehicle and a controller that is operable to cause a control system of the vehicle to initiate a first operation and a different, second operation. The controller determines whether first sensor information indicative of a state of the vehicle during the first operation exists. The controller sends a command signal to the control system to direct the control system to change vehicle operations from the first operation to the second operation responsive to determining that the first sensor information is lacking. The controller obtains second sensor information from the sensors based on the second operation and determines a condition of the vehicle based on the first and/or second sensor information.

Abstract: A locomotive inspection system includes sensors that are selectively coupled to a locomotive during an inspection or maintenance event for the locomotive and a controller that is operable to cause a control system of the locomotive that controls plural operations of the locomotive to initiate a first operation and a different, second operation. The controller determines whether the control system has first sensor information indicative of a state of the locomotive during the first operation. The controller sends a command signal to the control system to direct the control system to change locomotive operations from the first operation to the second operation responsive to determining that the control system lacks the first sensor information. The controller obtains second sensor information from the one or more sensors based on the second operation and determines a condition of components of the locomotive based on the first and second sensor information.

Abstract: A locomotive engine control system includes one or more processors operably connected to fuel supply devices. The fuel supply devices are configured to supply fuel into different corresponding cylinders of an engine. The one or more processors are configured to monitor a fuel quantity injected into the cylinders of the engine before and after communication of an overfuel control signal. The overfuel control signal commands the fuel supply device corresponding to a first cylinder of the cylinders to supply excess fuel into the first cylinder. Responsive to the fuel quantity that is monitored not decreasing after the communication of the overfuel control signal, the one or more processors are configured to determine that the fuel supply device corresponding to the first cylinder is defective, and may generate one or more control signals indicative of the fuel supply device corresponding to the first cylinder being defective.

Abstract: A data distribution system for a vehicle includes a data distributor module that is communicatively coupled with a data acquisition module that obtains values of available data parameters related to operation of the vehicle, a service module that provides functions for the vehicle based on the values, and a memory. The data distributor module receives a request list from the service module that includes one or more requested data parameters of the available data parameters. The data acquisition module stores the values of the requested data parameters in the memory. The data distributor module retrieves the values of one or more of the requested data parameters from the memory and communicates the values that are retrieved to the service module for the service module to use the values that are retrieved to provide the functions for the vehicle.

Abstract: Methods and systems for preserving content in a data recorder are provided. The method includes acquiring at least one of image data and audio data relative to an environment in a vicinity of a camera, receiving a data preservation request, and stamping the at least one of image data and audio data for future download using the data preservation request.

Abstract: A locomotive communication system for communicating between a locomotive and a fixed site. A communication system commissioning process is utilized to ensure that the locomotive phone number and locomotive road number are paired at the fixed site so that data downloaded from the locomotive, in response to a call from the fixed site using the locomotive phone number will be identified with the correct locomotive road number.
