Abstract

An ATC (Automatic Train Control) system utilizing digital train radio for the Shinkansen line has been developed. LCX (leaky coaxial cable) system along the track transfers information for train control such as: train location information from the on-board ATC system and distance-to-go information from the groundside train protection equipment. Applying the developed technology, it is expected that track circuits in the section between switch stations become unnecessary for train separation control. The quality of digital communication by LCX and the accuracy of train location measured by trial tests were both sufficient enough to put the system into practical use. East Japan Railway Company decided to apply the technology for the substitute block system of the Tohoku and Joetsu Shinkansen
