Stray current is the part of the current caused by a direct current (DC)-traction system that follows paths other than the return circuit. Stray current leakage and the corrosion caused by these currents is more of an issue in low resistivity soils and embedded tracks, which typically run through major traffic areas, city centers, and threads between utility lines that require the rail to be continuously isolated to provide superior track-to-earth resistance. This report documents best practices for those seeking guidance on design, maintenance, and testing of stray current control (SCC) for rail transit systems. The report is based on a study of both national and international transit agencies and is formatted as a reference guide. It not only includes information and resources needed to implement and evaluate SCC and mitigation measures but also lists testing and maintenance strategies for transit operators.
