# Tokyo Metro 02 series

The Tokyo Metro 02 series (東京メトロ02系, Tōkyō Metoro 02-kei) is a retired electric multiple unit (EMU) train type operated since 1988 by Tokyo Metro on the Tokyo Metro Marunouchi Line subway in Tokyo, Japan. Its design is based on the Tokyo Metro 01 series.

## Operations

A total of 336 cars were introduced into service from 17 October 1988 in 8 batches. 53 six-car trainsets (batches 1 to 7) operate on the main section of the Marunouchi Line, while the Hōnanchō branch uses six three-car trainsets (batch 8).

## History

The first trains entered service from 17 October 1988.
In March 1998, Automatic Train Control was introduced on the 02 series, which was supplemented with a Train Automatic Stopping Controller (TASC) system allowing them to stop automatically at stations since November 2002.

### Hōnanchō branch sets

In 1996, six 3-car 02 series sets were introduced for use on the Hōnanchō branch line. These sets feature an altered livery with a black stripe atop the waistline band. Internally, LED passenger information displays are used, and the longitudinal seats use piped side partitions. After Hōnanchō Station was upgraded in 2019 to accommodate 6-car trains, two of these sets were scrapped in 2021.
In July 2022, Tokyo Metro announced that 3-car trains would be withdrawn from the Hōnanchō branch line from 27 August of that year.

### Refurbishment

The 02 series fleet went under major refurbishment, with the first treated trains returning to service from February 2010. Refurbishment included the use of new Toshiba PMSM (permanent magnet synchronous motors), as fitted to the new Chiyoda Line 16000 series trains, offering energy savings of approximately 10%. Internally, pairs of 17-inch LCD passenger information monitors were installed above the passenger doors. The interior was finished in a pale salmon pink colour reminiscent of the original 300 series trains used on the line, and externally, a white "sine wave" design was added to the red bodyside stripes, again reminiscent of the 300 series livery.

### Withdrawal

A fleet of 53 new six-car trains was introduced in fiscal 2018 to replace the 02 series trains by fiscal 2023. The new trains are classified as Tokyo Metro 2000 series.
The last 02 series set was withdrawn in 2024.

### Overseas use

Two 02 series cars were transferred to FEATI University in the Philippines for training use.
