Recent Research and Development of Railway Signalling and Telecommunications


Tetsuo TAKASHIGE
Railway signalling and telecommunications need to safe transportation of train. Shinkansen and micro electronics (ME) of signalling system have contributed to development of signalling and telecommunications. Now, new train control system, mass data transmission by millimeter wave, safety design method of ME equipments are being developed. Protection of ME equipments from surge of a thunderbolt and reduction of radio frequency interference by a high speed train and magnetic induction from new type vehicles to signalling and telecommunications equipment are the problems to be solved. This paper describes recent research and development of railway signalling and telecommunications mainly in Railway Technical Research Institute.
