A Study on Performance Requirements of Doorstep Equipments for Both the Low and the High Level Platforms

저상 고상 승강장 겸용 승강문 스텝 성능조건에 관한 연구

Heights of a platform above the rail for the passenger train in the country are classified into two categories such as the low level (500mm; mainline) and the high level (1,135mm; metropolitan subway line) platforms. In order to operate similarly both a mainline railroad and a metropolitan subway line, as the requisite door safety system, it is necessary to develop the doorstep equipment of the rolling stock regardless of both the low and high level platforms. In this study, performance requirements of doorstep equipments used for two types of platforms are examined on the supposition that the train only for the low level platform could stop in the both low and high level platforms.
