IEEE 3175-2025

The guide provides principles, techniques, and data for the engineering design, installation, commissioning, as well as control and mitigation methods for stray currents associated with dc rail transit systems. The principles associated with this guide may be applied to transit structures and should take into account any transit structure that can be impacted by the generation of dc stray current. Although the principles outlined in this guide may, in theory, be extrapolated to non-transit structures, this guide does not do so, and the user is encouraged to seek further professional advice for non-transit structures.

Stray current corrosion issues associated with dc rail transit systems are well documented. However, there is a need for a concise guide document that can be used by transit agencies as a framework for initially designing these systems. This guide will assist transit agencies in the establishment of key processes as well as design and maintenance requirements for the mitigation of stray current effects on new and existing dc rail transit systems. The guide will serve as a knowledge base for transit engineering personnel to mitigate dc stray current problems and to take appropriate proactive measures.

New IEEE Standard - Active. The stray current corrosion issues associated with dc rail transit systems are well documented. However, the need for a concise guide document that can be used by transit agencies as a framework for the initial design of systems and for the ongoing maintenance of those systems has been identified. Assistance is provided by this guide to transit agencies in the establishment of key processes, as well as design and maintenance requirements, for the mitigation of stray current effects on new and existing dc rail transit systems. A knowledge base is provided by the guide for transit engineering personnel so that stray current problems may be reduced and appropriate proactive measures may be taken.
