In this paper, we introduce the network infrastructure in an advanced emu test line in Deabul. New technology has been applied to advanced EMU(DMU, integrated broadcasting system, black box and etc). In order to efficient and safely test of new developed train, failure, operation, status of test line and weather information should be monitored in real time. We has implemented a wireless and optical network infrastructure for reliability and scalability. The wireless communication capability between a car and ground is 20Mbps and back-hole network has 50Mbps of the communication performance. The network between test tracks and control office was established in the optical network. That can improve communication reliability.

On this paper we propose how to apply the vision system for monitoring a platform safety. The vision system is tested in real platform in a deagu subway station. According to the result of field test we propose how to use vision system for monitoring a platform safety. The result showed that it had a high performance to detecting ratio.
