<p>PROBLEM TO BE SOLVED: To provide a track deviation measurement system which can be realized in low cost without receiving troubles due to vibration in running of a train and natural environment.SOLUTION: A track deviation measurement system includes a plurality of electrolyte type clinometers provided at a plurality of predetermined positions in a rail and sleepers so as to sense displacement vertical to a longer direction which is a vertical deviation component of the rail, a plurality of reference rods which each have one end fixed to the rail or the sleepers, and are successively arranged along the rail in order to sense displacement horizontal to the longer direction which is a horizontal deviation component of the rail, targets each provided in the other end of the reference rod, and a non-tactile displacement sensor which is fixed to the rail or the sleepers in a position corresponding to the target and measures a horizontal separate distance from the target.</p> |
