장기간 수명주기(Life Cycle)을 갖는 도시철도차량은 초기 도입비용보다 유지보수비용이 많은 비중(70%~80%)을 점유하고 있으므로 효율적인 유지보수 연구를 통하여 유지보수 비용의 절감과 대형시스템의 수명 연장을 추구하는 일이 무엇보다 시급하다. 이를 위해 신뢰성기반의 유지보수체계에 대해 여러 산업분야의 국내?외 사례 조사?분석을 통해 도시철도차량 신뢰도/가용도 관리시스템을 구성하였다. 본 연구에서는 이 시스템이 가져야할 주요 기능을 상세히 정함으로서 성공적인 시스템 개발이 될 수 있도록 하였다. It is very important that reduce the maintenance cost and extend life time of the urban transit EMU through effective maintenance method research. The maintenance cost of the urban transit EMU shares 70%~80% of it's life cycle cost. It means that the maintenance cost is bigger than the introduction cost of the urban transit EMU. We were survey and analysis for the reliability centered maintenance system of internal and external many industry parts. And we composed the reliability/availability management system of the urban transit EMU' maintenance. In this study, in order to success the system development, we decided the major functions of reliability/availability management system of the urban transit EMU' maintenance.

The urban transit vehicles has very complicated structures composed electric and mechanical parts and systems. Its system is important to insure operating stability pursuant to massive transfer. Also its system takes a lot of maintenance cost than constructing cost due to its system which has longtime life cycle. Generally it is know that maintenance cost affect a lot on total cost because its life cycle cost takes a part more than 60~70%. For these reason it is really important to reduce its maintenance cost through efficiently operation and maintenance management system construction.

Urban transit is a large scale complex system which combines rolling stocks, power supply, signalㆍcommunications, tracks & stations. Therefore standardization is very important because it is difficult to find causes when failures or accidents occur. The standardization of urban transit increases safety and economical efficiency, and also gives passengers convenient and comfortable feeling. We, Korea Railroad Research Institute(KRRI), had finished the 1st phase study of urban transit standardization from "95 to "06. And 2nd phase study on rolling stock, information & communication, subway station has been performed from July "07. In this paper, we introduce what we study on urban transits standardization during coming 5 years. We expect our study will contribute to increase the efficiency of urban transit.

Railway in Japan has been changed every apr. 20 years as follows, since the war ended in 1945. Shinkansen which was the first high speed train in the world began to revenue service in 1964, and a national railway authority was privatized segmentally in 1987, and after 20 years later from then, the ticketing service using IC card was accomplished. In this research, we review these changes in Japan in the administrative aspects on railway technology, and R & D aspects of the Railway Technical Research Institute, JR East and JR West which are railway corporations. Also we introduce the present status and future of railway technologies in Japan which railway experts diagnosed. In the twenty-first century, the needs of the times for railway have been enormously changed due to a low birth-rate, an aging society, environmental pollution and energy problems and etc. Because we have very similar problems to them like Japan, we could get lessons from Japanese cases in setting the direction for the development of railway technologies.

Urban transit is defined as " Transportation facilities and carriage by track like railway where is constructed and operated in urban area" in Korean urban railway law. Several hundreds of urban transits are operated in the world, and Korea also has 19 lines 590km in several cities like Seoul, Busan etc. In this paper, we classify urban transits and describe the general characteristics of urban transit. And then review major technical issues and present the direction to technical progress.
