Learning from past railway accidents contributes to the improvement of safety and prevention of undesirable events. The “7.23” Yong-Wen line high-speed train accident in 2011 led to a full-blown effort in the research of electromagnetic interference (EMI) protection and better safety for railway signaling. Ensuring railway safety and efficiency necessitates a study of analysis methods to evaluate the influence of EMI over reliability and safety, especially in railway signaling.
The design of electrical railway vehicles, including high-speed trains and subway trains, need to include attention to EMI/EMC problems that contribute to serious concerns regarding safety.
