The Tokyo Metro 2000 series (東京メトロ2000系, Tōkyō Metoro 2000-kei) is an electric multiple unit (EMU) train type operated by Tokyo Metro for use on the Marunouchi Line in Tokyo, Japan. They serve as a replacement for the Tokyo Metro 02 series that was in service on the Marunouchi Line from 1988 to 2024.[3]
The trains are built by Nippon Sharyo and Kinki Sharyo, with Toshiba supplying the electrical equipment.[4] They are fitted with permanent magnet synchronous motors and silicon carbide traction inverters, which are expected to reduce the power consumption by about 20%, compared to the previous Tokyo Metro 02 series.[5][6]
Self-steering axles similar to those of the 1000 series are fitted to the bogies.[4]
Formation
The trains are formed as six-car sets.[4]
