a controller configured to receive detection times at which passage of one or more vehicle systems by a detection device disposed along a route is detected, the controller also configured to determine sensed locations of the one or more vehicle systems when the one or more vehicle systems were detected by the detection device, the controller configured to receive the sensed locations from one or more location sensors of the one or more vehicle systems, the controller configured to determine the sensed locations when the one or more vehicle systems were detected by determining the sensed locations received by the one or more location sensors at the detection times,
the controller configured to identify a condition or state of the detection device by comparing the sensed locations determined by the controller at the detection times with a device location of the detection device.
