Mitsubishi Electric delivers equipment for train control system on Tokyo Metro's Marunouchi line

Mitsubishi Electric Corporation (TOKYO: 6503) has announced that it has filled an order by Tokyo Metro Co., Ltd for radio equipment to be used in what is believed to be Japan´s first communication-based train control system (CBTC) for subways, the company said.

The delivery includes wayside radio equipment for a branch of Tokyo Metro´s Marunouchi Line between Nakano-sakaue and Honancho stations and on-board radio equipment for a train that will be operated on the line for verification purposes.

Tokyo Metro will evaluate and verify the equipment through trial operations, aiming at full commercial deployment on the entire Marunouchi Line by the end of fiscal year 2023.

CBTC systems are being used to upgrade the detection of train locations and management of train intervals (headways), which are conventionally performed with wayside equipment (e.g., track circuits and signals). In particular, CBTC systems can enhance high-density train operations and reduce wayside equipment maintenance costs.
