In DC rail transit systems, the running rails are usually used as the return conductor for traction current. This arrangement mainly focuses on economic considerations, since it does not require the installation of an additional return conductor. When this type of feeding is used stray current corrosion occurs because of the mechanism of current transfer between metals and a conductive electrolyte such as concrete, soil and water. Stray currents can cause safety risks, thus making the modeling of stray current magnitude is an important element of the holistic design for a dc transit system. Overview of the factors which have influence to the magnitude of the stray currents is made in this paper.
