Claim:
1. A system comprising: at least one application device configured to be disposed on-board a vehicle system having at least one vehicle traveling along a route having first and second conductive tracks, the at least one application device configured to be at least one of conductively or inductively coupled with at least one of the conductive tracks; a control unit configured to control supply of electric current from a power source to the at least one application device in order to electrically inject at least one examination signal into the conductive tracks via the at least one application device; at least one detection device configured to be disposed on-board the vehicle system, the at least one detection device configured to detect the at least one examination signal passing through a test loop; and at least one processor configured to be disposed on-board the vehicle system, the at least one processor operably coupled to the at least one detection device and configured to identify a failure of the vehicle system to adequately shunt electrical signals between the conductive tracks based upon the at least one examination signal detected by the at least one detection device.
