Abstract

This paper discusses assurance technology and its application in autonomous decentralized railway signalling systems. It is known as a technology utilized in various situations for the replacement of one system with another without stopping the system operation of these systems.

East Japan Railway Company adopted assurance technology on the introduction of D-ATC (Digital Automatic Train Control system) to the train control system operating on the busiest lines of the Tokyo metropolitan area. It was not only able to contribute to step-by-step construction (migration) and to improving the reliability of the D-ATC, but also effective in the enhancement of functionality of the railway signalling system which directly relates to railway business.
