A electric railway is unique system that electric trains consumed huge electric power are travelled and is much interested with EMC. There were several problems exceeding the standard in the frequency range of 9kHz to 150kHz because the radiation noises were moved the higher frequency range according to developing the power electronic technology. It is studied the experimental confirmation of main noise source on the electric train and the analytic simulation for reducing the noise level in this paper.
