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.
