In JR Central, track inspection data including track irregularities, vehicles agitation, and train noise is measured by high speed track recording car. The track inspection data has the deviation of a sampling interval because of wear of a wheel, or the influence of idling and gliding. We have devised a new method of adjusting the deviation by combining cross-correlation and up sampling processing. Moreover, it has become clear that the track inspection data from Tokaido Shinkansen can be adjusted with high accuracy by the method. Advanced analysis of track inspection data and efficient maintenance work using tamping machine are expected by application of this method. In this paper, we introduce the algorithm of the method and data flow by explaining the software which we have developed. Furthermore, we describe some examples of application to track quality management utilizing this method.
