A Train control system is intended to assure train operation safety and to improve train operation efficiency. To perform these missions the Train Control System consists of train safety space control part train route control part and train operation management part. Train control technology changed from track circuit based to wireless based. And Wireless based train control technologies were developed by some railway signaling companies in Korea. To commercialize these control technologies the development project is carried now. This project did analyze system requirements and made the system development specification. Now this project finished system functions allocation which will be performed by some subsystem. This paper describes roles of each function and the allocation of these functions to each subsystem.

Studies suggested an increase in the competitiveness and roles of mainline railways like speed and accessibility improvement, as a fundamental direction of the National Transport Network Plan. At this point, topics presented especially for strengthening the role of human and environment centered transportation: as to the greatly improved speed competitiveness, there are an operational speed above 180㎞/h ∼ 200㎞/h and traveling within 2 ∼ 3 hours among big cities. As to accessibility improvement, there are accessibility to main railway stations within 30 minutes, and the improvement of accessibility, safety, eco-friendliness, amenity etc. As a part of these suggestions, field specific plans were proposed for the establishment of expressed mainline railway network in Korea such as train’s, civil structures, trolley lines etc. In this paper we analyzed the conventional lines and systems to figure out whether to change details in terms of H/W of signaling system. Additionally, we reviewed the compatibility or difference of signalling system depending on train’s speed. With this result, we deduced the number of virtual blocks specific to the speed of 180㎞/h, 200㎞/h and 230㎞/h, which were showed for the speed improvement considering each variable like blocks, braking distance etc. In this way, we suggested the railway signal system establishment plan considering safety operation.

국가기간 교통망 계획의 기본방향으로 속도향상, 접근성 개선 등으로 간선철도의 경쟁력과 역할 증대가 제시됨에 따라 속도경쟁력 대폭 향상방안으로 운행속도 180㎞/h~200㎞/h 이상, 대도시간 2~3시간 이내 이동 및 접근성 개선 사항으로 주요 철도역에 30분 이내 접근, 안전성, 친환경성, 쾌적성 등 향상을 통한 인간 · 환경 중심적 교통수단으로서 역할 강화라는 화두가 제시되었다. 이에 고속화 간선철도망 구축을 위한 분야별(차량, 토목구조물, 전차선 등)방안이 제시 되었다. 이에 신호시스템 분야에서는 기존의 시스템을 파악하여 속도별로 시스템의 적합성내지 타당성을 통해 각 변수(폐색, 제동거리 등)를 감안하여 신호 현시별 시스템 구축방안을 제시하였다.

In this paper, we have checked a method of performance evaluation for electronic pedal, which is a core technology of HBD for detecting the axle temperature of high-speed train. As it is practically impossible to conduct train speed test of 500 ㎞/h, we utilize a high speed rotor for evaluating high speed performance of the electronic pedal instead. According to this method, we found that the measurement results by the velocity measuring instrument is similar with the ones from this research through the high speed rotor. In conclusion, it will be possible to conduct reliability evaluation for high speed performance for Beacon, Balise and RFID, which are utilized for transmitting vital information of train control systems through using the rotor.
