Development of Sliding Step and Test Results

Abstract

In the platform of the urban transit system, a certain gap is inevitably made between the subway vehicle and the platform, and the gap gets wider in the curved area of the platform. This gap contributes to decrease passengers’ safety. Nowadays plug-in type doors are installed in the newly designed urban transit system. It is worldwide trend to reduce the noise coming from the outer side of vehicle. This plug-in door basically needs wider gap between door and platform and it maybe raise a serious accident. Sliding step is suggested to minimize gap and to overcome this safety problem at platform. In this paper, we presents development process for sliding step, trends of sliding step, development plan, technical description and test results.
