Abstract
A system includes a route examining system and an off-board failsafe controller. The route examining system is configured to examine a route on which a first vehicle system is moving and to generate an inspection signal based on the route examination. The inspection signal indicates a status of a segment of the route as damaged or undamaged. The off-board failsafe controller is configured to receive the inspection signal from the route examining system. Responsive to a lack of receipt of the inspection signal within a designated time period which indicates communication loss with the route examining system, the failsafe controller is configured to generate a warning signal for communication to a second vehicle system. The warning signal is generated to direct the second vehicle system to (i) avoid traveling over the route segment or (ii) travel over the route segment or another route segment at a reduced speed.
