Personnel maintaining or repairing the railway tracks or signaling device around tracks may experience the sensory disorder when they do routine works for many hours and they may not recognize the leading to train accidents. In order to prevent such train accidents that may occur because railway track workers are unable to recognize the approaching train, a safety-equipment is developed to make the approaching train send signals. We developed the new alarm equipment for protection of trackside maintenance workers using radio signals.

철도의 선로변에서 선로나 신호설비의 유지 보수 작업을 할 경우 감각 차단현상에 의해 작업 전후방 일정거리에 열차가 접근하고 있어도 열차를 인지하지 못하여 사상사고가 자주 발생하고 있다. 이러한 철도 선로변의 사상사고 저감을 위해 무선통신에 의한 안전설비를 설계 및 개발하였다.

Workers maintaining at the railroad trackside may collide with the train since they cannot recognize the train approaching because of the sensory block phenomenon occurred due to their long hours of continued monotonous maintenance work. To reduce these casualty accidents of maintenance workers working at the trackside of railroad, we developed the wireless communication-based safety equipment for preventing accidents. The motor-cars for maintaining trackside facility have unique operational patterns suitable for urban environment. The several mechanism for developed safety equipment are represented in this paper.
