Highly reliable communication will raise railway safety and reliability
Mitsubishi Electric Corporation 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 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. However, increasing demands to ensure railway system safety and security are creating needs for advanced security solutions and radio equipment that is highly resistant to radio wave interference.
Mitsubishi Electric was able to respond to these demands by leveraging radio communication technologies that the company has cultivated over the years in fields including aerospace. The company will now assist Tokyo Metro in verification tests of the recently delivered wayside and on-board radio equipment, aiming at the launch of a commercial CBTC system by the end of fiscal year 2023. Going forward, Mitsubishi Electric expects to expand its business in transportation systems by supplying various railway signaling systems to railways around the world.
