As the train runs faster, it becomes necessary to secure the reliable stability and high riding comfort. One of the important factors to affect the vibration to the train is the status of the rail on which the train itself runs. It is not too much to buckle down to inspect the rail and maintain the disarranged section of the rail. Until now the maintenance of the high speed rail has been performed by the rail measuring car based on the 3-chord method. But the results of it have some distortion of the rail geometry and the inspection speed is low. Thus the authors suggested the installation of the highly efficient track inspection system to HSR-350x. The results of running test showed the better performance and good reliability. Since then, the measurement test has been performed. One of the important factors of track measuring system In is the position detecting. During the test, we found the performance of the position detect was excellent and report the result in this paper.
