JAPAN: The first of 53 six-car Class 2000 trainsets entered revenue service on the Marunouchi Line of the Tokyo metro on February 23.
Nippon Sharyo is supplying the 600 V DC trainsets from its Toyokawa factory. They are equipped with permanent magnet synchronous motors supplied by Toshiba. Deliveries are scheduled to be completed in 2022, and the new fleet will replace the Class 02 trainsets.
Mitsubishi Electric is supplying a condition-based maintenance system incorporating its Train Information Monitoring & Analysis technology, which is based on Internet of Things concepts.
