It is said that the rail corrgation which is has the cycle of 1.2 m generates unsprung mass increase on high-speed Shinkansen. This wavelength corrugation can remove by the synchronization block grinding. We tried the corrugation removal by the grinding car which has 32 rail grinding head with the function of synchronization block corrugation removal by the specific path pattern. As a result of the grinding , we could confirm effect of the synchronization block corrugation removal.
