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.

Recently, with expansion and advent of the wire&wireless networks has been set up by various heterogeneous networks in urban transit networks. It's focussing on an interworking technology. As same as way, In a subway & railway monitoring system networks has been set up by various heterogeneous technologies such as IEEE802.11 WLAN, IEEE802.15 WPAN, DVBT, UWB, BinaryCDMA, ZigBee. These heterogeneous technologies is deeply investigating for the purpose of interworking and easy control as a research area. In this paper, we propose using VoiceXML based of XML for ensure interworking within heterogeneous subway & railway networks. Therefore It will be provide service for staff who has moving and anywhere, anytime in outside. Eventually, we expect that confirm efficiency of effective system through this study.

Urban transit consists of signaling system, railway systems, power facilities systems, information and communication system and the other complicated facilities. There are many new technologies to analysis the requirement of for information and communication system. The more system is complicate, the more system design error occur frequently in development of information and communication system. Now, we need to reduce the error by analysis the behavior of the requirements of it. Thus in this paper, we suggest the way to analysis the behavior of the requirements by using the computer aided design tools.
