Abstract

Although insulation equipment is installed, it is inevitable to avoid the stray current because rail is the return way of the direct current that is power of electric motor car. In this paper, by the investigation of the present state of underground facilities, and looking into the reason of electric corrosion, and analysis of corrosion accident cases of inside and outside of the country, fundamental data, to reduce of stray current and to prevent electric corrosion, were accumulated to enhance the safety of railway operation service.
