The Tokyo Metro 8000 series (東京メトロ8000系, Tōkyō Metoro 8000-kei) is an electric multiple unit (EMU) train type operated by Tokyo subway operator Tokyo Metro on the Tokyo Metro Hanzomon Line in Tokyo, Japan, since 1981. [1]

Contents

A total of 190 cars (19 ten-car sets) were built between 1980 and 1994 by Kawasaki Heavy Industries, Kinki Sharyo, Nippon Sharyo, and Tokyu Car Corporation. [2]

Technical details

The train shares some design similarities with the earlier Tokyo Metro 6000 series on the Chiyoda Line and the Tokyo Metro 7000 series on the Fukutoshin Line, mainly the asymmetrical front and bodyshell with some cosmetic changes.

History

The first 8000 series trains were introduced on 1 April 1981, initially operating as 6- and 8-car sets. By 1982, all sets were lengthened to 8-car formations. Between 1987 and 1994, the fleet was lengthened again to 10-car formations. [4]

Due to a surge in ridership on the Tozai Line, the Teito Rapid Transit Authority (TRTA) procured three 10-car 8000 series sets and introduced them into service in 1987. TRTA also considered building more 5000 series trains, but its base design was over two decades old, and development of a new train type was still underway. [5] These 8000 series sets were transferred to Hanzomon Line services within a year. [4]

From 2004, a programme of refurbishment commenced, with some sets receiving VVVF control and three-phase motors. [2] In February 2016, set 8114 received full-colour LED destination indicators. [6]

Withdrawal

The 8000 series trains began to be replaced by new 18000 series trains from 7 August 2021. The first set to be withdrawn, set 8107, was removed for scrapping in August 2021. [7] [ better source needed ]

Two 8000 series sets remain in service as of December 2025. [4]
