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.
