Safety management system of the railway was introduced for the maintenance of the railway vehicle. Safety management system requests for the activities of reliability management system associated with the Reliability Centered Maintenance. Thus, in order to apply the process of RCM(reliability centered maintenance), auxiliary power supply unit is selected among the 13 major units in trainset. auxiliary power supply is the significant impact item in terms of service failure and the failure rate is also the highest. So, 59 components in auxiliary power supply unit were selected and statistical analysis was performed through analysis of the field data collected during commercial operation.. The maintenance work in the future should be based on the reliability analysis results. Also, the reliability analysis may be the starting point for RCM required by the safety management system of the railway.

With the development of vehicle production technology of recent, balance development of the standard model of urban rail operating agency-specific requirements are met, such as improved safety and convenience of maintenance, the ride is needed. In this study, the structure in dynamic load Below check the static strength through the analysis of the static load test results bogie frame, which is the main component of the travel device developed in line 7 new train and repeatedly acts I was verified a safe manner. The priority application standards for performance testing of urban rail vehicle and the results of structural analysis, to assess the safety due to fatigue endurance lead, load conditions applied to the load test, the fatigue test by applying the CODE615-4 standard UIC was conducted.
