ABSTRACT:
Method and apparatus for a railway navigation system which provides information defining the position of a railway vehicle on a track system. The system uses an on-board computer with a track database representing the locations of the rail lines, including locations of curves and switches. The system uses a turn rate indicator and a speedometer means to obtain a value for the curvature of the track on which the railway vehicle moves. Curvature data so obtained is compared with data in the track database to determine the position of the railway vehicle in relation to curves and switches of the track system.
