Abstract
A train registry system is overlaid upon an existing automatic train protection system and operates simultaneously with the automatic train protection system to collect redundant information that may be utilized in the event that the automatic train protection system computer and backup computer must be restarted or in the event a vehicle no longer communicates with the automatic train protection system computer. The train registry is comprised of a plurality of transponders mounted upon train vehicles and transponder readers mounted at wayside locations to extract information from vehicles and forward the information to the wayside computer.
