At Sanyo-Shinkansen, the high speed track confirmation car confirms track conditions prior to the first train eveiy morning. Authors examined the detection of gigantic track irregularity by adopting the inertial measuring method using axlebox acceleration of high speed track confirmation car. We confirmed that this method is accurate enough to detect the gigantic track irregularity compared to that obtained by track geometry car, though it is necessary to consider the gap of the location of measurement and the difference of the axle load between Shinkansen train and high speed track confirmation car. We also carried out the regression analysis, presumed the confidence interval, and obtained the prospects of setting the evaluation threshold.
