In order to operate trains both mainline railroad platform and metropolitan subway line platform, it is necessary to develop the door step equipment of the rolling stock regardless of low(500mm, mainline) and high level platforms(1,135mm, metropolitan subway line) because of the requisite door safety system. In this study, TMS-DCU interface is studied for low and high level railway platforms. As a result, Design circuit of TMS(Train Management System)-DCU(Door Control Unit) interface is suitable for telescopic sliding type doorstep unit to minimize damage to the carbody underframe of railway vehicles.
