This paper discusses Assurance Technology and the application in railway signalling systems. It is known as a technology for the replacement of a system without stopping the system under various situations. East Japan Railway Company adopted assurance technology on introducing D-ATC (Digital Automatic Train Control system) to the train control system operating in the most crowded 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 was also effective in the enhancement of functionality of railway signalling which directly relates to railway business.
