Stray Current Interference Simulation and Mitigation Associated with Light Rail Transit (LRT) Systems and Adjacent Metallic Pipelines – A Case Study

During operation of DC rail transit systems, DC current will follow the path of least resistance when returning to the Traction Power Substations (TPSS) to complete the electrical circuit. If the track-to-earth resistance (resistance between the train rails and surrounding soil) is not sufficient, current can leak off the LRT track system into the surrounding soil. Metallic facilities such as pipelines in the soil offer lower resistance paths for the current while returning to the TPSS.
