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]

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.

Original sets

  • Motor output: 160 kW
  • MT ratio: 6M4T
  • Total train power output: 3,840 kW
  • Control system: Chopper control

Refurbished (B-refurbishment) sets

  • Motor output: 165 kW
  • MT ratio: 5M5T
  • Total train power output: 3,300 kW
  • Control system: IGBT-VVVF control

History

The first 8000 series trains were introduced in 1981.[2]

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.[4]

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 The first set to be withdrawn, set 8107, was removed for scrapping in August 2021. [citation needed]
