Train Control System Using Track Circuit

Tetsuo TAKASHIGE


Existing automatic train control (ATC) is a highly safe system. But, it is desired to construct a new system to shorten headway and to be flexible to vehicle performance. The 1 step braking system shortens headway. Digital ATC is the 1 step braking system using track circuit. This paper describes the difference between existing ATC and the digital ATC and the notes for practical use of digital ATC. And it is also described to compare headway of fixed block system with that of the moving block system.
