Abstract: A route examination system determines a characteristic of a vehicle system traveling over a segment of a route under inspection, a characteristic of the route, and/or a characteristic of movement of the vehicle system over the segment of the route. The system also detects acoustic sounds generated by movement of the vehicle system over the segment of the route. The system selects a baseline signature representative of acoustic sounds generated by movement of the vehicle system or another vehicle system over a healthy segment of the route, and determines that the segment of the route under inspection is damaged based on a comparison between the baseline signature and the acoustic sounds generated by the movement of the vehicle system over the segment of the route under inspection.
