Since the opening of the Tohoku and Joetsu Shinkansen lines, the Centralized Information Control (CIC) system has been supporting safe and stable transportation. In order to cope with the increased speeds and volume of data transmission, NEC has adopted some innovative solutions. These have been deployed by East Japan Railway Company as an updated version of the CIC system and are contributing to the efficient supervision and maintenance of the system as well as to transportation safety. This paper summarizes the upgraded CIC system and discusses its features.
