Abstract: A route examining system includes first and second detection units and an identification unit. The first and second detection units are configured to be disposed onboard a vehicle system traveling along a route having plural conductive tracks. The first and second detection units are disposed at spaced apart locations along a length of the vehicle system. The first and second detection units are configured to monitor one or more electrical characteristics of the conductive tracks in response to an examination signal being electrically injected into at least one of the conductive tracks. The identification unit includes one or more processors configured to determine that a section of the route includes an electrical short responsive to the one or more electrical characteristics monitored by the first and second detection units indicating that the examination signal is received by only one of the first and second detection units.

Abstract: A system may include a coded test signal transmission system configured to transmit a unique coded test signal along a route, and a coded test signal receiving system configured to receive the unique coded test signal along the route. The unique coded test signal received by the coded test signal receiving system is used to determine one or more characteristics of the route.

Abstract: Systems and methods for monitoring a vehicle determine a baseline wheel rotational speed and wheel rotational speeds of a wheel for different positions along an outer perimeter of the wheel. One or more deviations between the wheel rotational speeds and the baseline wheel rotational speed are determined, and the deviations between the wheel rotational speeds and the baseline wheel rotational speed are correlated with one or more identified positions of the positions along the outer perimeter of the wheel. One or more of damage to the wheel or damage to a drivetrain of the vehicle is identified based at least in part on the one or more deviations being correlated with the one or more identified positions.

Abstract: A route examination system and method automatically detect (with an identification unit onboard a vehicle having one or more processors) a location of a break in conductivity of a first route during movement of the vehicle along the first route. The system and method also identify (with the identification unit) one or more of a location of the vehicle on the first route or the first route from among several different routes based at least in part on the location of the break in the conductivity of the first route that is detected.

Abstract: A route examining system includes first and second application devices, a control unit, first and second detection units, and an identification unit. The first and second application devices are disposed onboard a vehicle traveling along a route having conductive tracks. The control unit controls injection of a first examination signal into the conductive tracks via the first application device and injection of a second examination signal into the conductive tracks via the second application device. The first and second detection units monitor electrical characteristics of the route in response to the first and second examination signals being injected into the conductive tracks. The identification unit examines the electrical characteristics of the conductive tracks in order to determine whether a section of the route is potentially damaged based on the electrical characteristics.
