Summary

Modern high-speed trains on the bandwidth of the cable, safety, ability to resist electromagnetic interference and electromagnetic resistance and so on all have different requirements. Interoperability trend is no doubt, it can make the train more easily across national borders, and even of the continental shelf. And, of course, here said the cable also must conform to the unified standard of ERTMS/ETCS, the standard innovation in the GSM - R radio technology is applied to train control, at the same time, and continue to apply the old line control system (relay interlocking) to ensure the security of the wire and redundancy.
