The Tokyu 2000 series (東急2000系, Tōkyū 2000-kei) is a Japanese commuter electric multiple unit (EMU) train type operated by Tokyu Corporation in the Tokyo area of Japan since 1992. Until 2019, the type was used on Tokyu Den-en-toshi Line and Tokyo Metro Hanzomon Line inter-running services. Presently, they are used on the Tokyu Ōimachi Line, having operated on the line since 2018. Three 10-car sets were built, all of which were converted to five-car sets from 2018.

From 2019, all sets were reclassified as the Tokyu 9020 series (東急9020系).

Operations

The 2000 series sets are used on the Tokyu Ōimachi Line and were formerly used on Tokyu Den-en-toshi Line and Tokyo Metro Hanzomon Line inter-running services until 2019. They are not capable of running through onto the Tobu Skytree Line, and had circular "K" stickers on the centre front cab window to indicate this.

Design

Based on the earlier Tokyu 9000 series EMU design, two sets were introduced in 1992, followed by a third in 1993. The first two sets were delivered with roller blind destination indicators, whereas the third set was delivered from new with 3-colour LED destination indicators. All three sets have since been modified with full-colour LED destination indicators.
