Abstract

The Tohoku and Joetsu Shinkansen lines which are being built are to have a telecommunications system using leaky coaxial cables. This will increase the number of telephone circuits which are necessary for the administrative functions and for serving the public while also increasing the telecommunications capacity. The author describes the leaky coaxial cables and the telecommunication/train radio systems which are to be installed on the two new lines.
