DC Stray currents represent serious problems for any electrified railway system. This paper describes a complete simulation model for evaluating rail potential and stray current for the Tehran multi-train DC railway system based on different earthing systems. In the present paper, a complete analysis of the results is presented. The simulation results clearly indicate that earthing system arrangements and other parameters influence stray currents and rail potential. The simulation results show the performance of three ground system types: grounded, ungrounded, and diode-grounded systems on rail potential and stray current.
