Abstract
An automated fault reporting system for a train includes a controller that gathers information concerning malfunctioning wayside status devices and automatically reports the information to an appropriate party. In one embodiment, the control module uses a positioning system and a database including device locations in order to determine when the train is near a device. If no status information is received from the device as the train approaches, or the status information indicates a problem, the train is allowed to continue at a reduced speed to allow the operator to visually confirm that it is safe to proceed. If an area monitored by the device has been passed, or if the operator indicates that there is no problem, or the device fails to respond, the controller records and reports the malfunction.
