History
The 8000 series was introduced by Teito Rapid Transit Authority (also known as Eidan, now Tokyo Metro) two years after Hanzomon Line was opened. When the Line was opened, TRTA initially decided not to have its own train and borrowed Tokyu 8500 series instead, but TRTA changed its mind as the Line was extended. The 8000 series trains have been engaging in through-services towards Tokyu Den-en-toshi Line from the very beginning, and also to Tobu Lines since 2003. Withdrawal commenced in 2021 following the introduction of 18000 series, and Tokyo Metro planned to replace all 8000 series by financial year 2022, but deferrred for three years.
It is not well known that the 8000 series were also used on Tozai Line in 1987-89 with purple bands.
Current Operations & Future Prospects
The 8000 series run Tokyo Metro Hanzomon Line, Tokyu Den-en-toshi Line, Tobu Nikko and Isesaki Lines. The series is common on this route even during off-peak times. Tokyo Metro will replace all 8000 series trains with the 18000 series by early-2026.
