Stray current and stray current–induced corrosion remain concerns among transit agencies, electrolysis committees, utility owners, providers, and electric railway carriers across the globe. It is easier to implement stray current isolation, mitigation, and collection options on a newer transit system with proper foresight and planning by following the logical sequence of the design process than to maintain a stringent maintenance and testing regime on an older system.
The TRB Transit Cooperative Research Program's TCRP Research Report 212: Stray Current Control of Direct Current-Powered Rail Transit Systems: A Guidebook allows transit agencies, design, and maintenance practitioners to influence new system construction, extensions, and maintenance and operation of existing systems.
Improving the Safety and Sustainability of Stray Current Control of DC-Powered Rail Transit Systems (PowerPoint slide deck) highlights the research review and guidebook development.
