A switch reporting device including at least one display screen, a high resolution camera, a code reader, at least one memory and one or more processors, the switch reporting device configured to determine a position of an unmonitored switch in a railway by capturing an image of one or more portions associated with the unmonitored switch, generating switch position data based on the image of one or more portions associated with the unmonitored switch, and updating a switch position record for the unmonitored switch with the switch position data. The switch reporting device includes one or more mobile computers or an EOT device for monitoring and reporting switch position data for an unmonitored switch.

IMAGE-BASED MONITORING AND DETECTION OF TRACK/RAIL FAULTS

A system and method for monitoring a track and/or rail employs one or more imagers mounted to a railcar and directed to image the track and/or rails wherein the images are geo-tagged with location data. Geo-tagged images are processed to determine at least track gauge and/or at least rail fastener integrity. The system and method may also determine other track and/or rail integrity issues including, e.g., rail fastener integrity, rail profile, rail alignment, center point dip, cross level, rail cant, wheel wear, wheel integrity, rail wear, rail defects, and/or rail temperature. The system and method may also determine when inspection and/or maintenance of the track is indicated, and provide selected records of where and/or when such inspection and/or maintenance is indicated.

VEHICLE COMMUNICATION SYSTEM, CONTROL SYSTEM AND METHOD

A vehicle control system includes a controller that communicates between a first vehicle and a second vehicle and/or a monitoring device in a vehicle system. The controller determines a communication loss and, responsive to determining the communication loss, switches to communicating via a different communication path. The controller also determines an operational restriction on movement of the vehicle system based on the communication loss that is determined, obtains a transitional plan that designates operational settings of the vehicle system at one or more different locations along a route being traveled by the vehicle system, different distances along the route being traveled by the vehicle system, and/or different times. The controller automatically changes the movement of the vehicle system according to the operational settings designated by the transitional plan to reduce the movement of the vehicle system to or below the operational restriction.
