ABSTRACT:
A method and apparatus is provided for accurately locating a train or a track repair vehicle along the track, or to locate accurately a track defect. When measuring track geometry, i.e. gage, cross level, warp, the measuring device moves foot by foot along the track and senses and stores a historical profile of various track geometry parameters. The historical profile is stored in a form usable in a processor in the geometry measuring equipment on a train or repair vehicle. The vehicle is run for a set distance to generate a real time profile which is correlated with the historical profile to get a match and a starting location. Then the vehicle proceeds foot by foot correlating the real time profile with the historical one so that an exact location on a specific track can be determined.
