A system to emulate railway dc systems is presented in this paper. The emulator is designed to simulate the behavior of railway systems in terms of stray currents and touch voltages. Power electronics circuits are used as variable resistors to simulate the train motion. The emulator provides a test bed to not only study and analyze the effects of stray currents and touch voltages, but also to evaluate techniques that mitigate these effects before they are physically implemented. The proposed emulator system is verified through simulation studies and hardware experimentations.
