Japanese railway has already started high speed train, Shinkansen in 1964 and introduced the rail track inspection car. In Korea, high speed railway, KTX has started commercial service last year and passengers is increasing. To secure the safety and reliability of high speed railway, it is necessary to inspect and maintain the rail regularly. In this paper, we introduce Japanese track irregularity measuring system through track inspection car. Japanese technical skills are very helpful to us to develop tack inspection measuring system.
