Reliability analysis-based maintenance system has the merit than elapsed time-based preventive maintenance system. First, it is possible to active handling of rolling stocks failures. In the past, Failure handling activities began when after increase failures rapidly. But if we can continuous manage of reliability than changing of failure tendency can know more quickly. Second, It is possible to using maintenance resources effectively. We can look forward to cost reduction to distributing of much less failures parts's maintenance resources. KORAIL builds reliability system called KTX-RCM for operating high-speed rolling stocks. But existing rolling stocks have not reliability system from the past. Fortunately, KORAIL started ERP system called KOVIS at 2007. KOVIS includes maintenance data for reliability analysis. So in this study analysis failure data for getting reliability number about existing passenger car. And we desire to maintenance connection plan.
