Other facilities required include self-diagnostics for transmission conditions, easy status monitoring, and quick analysis of and recovery from faults and emergencies. Recently, as new train control systems for the Tokaido Shinkansen have been constructed, a dedicated fail-safe transmission system was developed and incorporated, with innovate features that could not be achieved with a general- purpose transmission system. 1 Introduction The Train Control System of Tokaido Shinkansen (552.6 km between Tokyo and Osaka) consists of three sub-system, Automatic Train Protection(ATP), Electronic Interl
