The Tokyu 2000 series (東急2000系, Tōkyū 2000-kei), reclassified Tokyu 9020 series (東急9020系, Tōkyū 9020-kei) from 2019, is a Japanese commuter electric multiple unit (EMU) train type operated by Tokyu Corporation in the Tokyo area since 1992. They were used on Tokyu Den-en-toshi Line and Tokyo Metro Hanzomon Line inter-running services from 1992 until 2018,[1] as well as the Tokyu Oimachi Line since 2018. Three 10-car sets were built by Tokyu Car Corporation between 1992 and 1993, all of which were shortened to 5-car sets by March 2019.

Operations

These sets are used on the Tokyu Oimachi Line.[1] Originally, they were used on Tokyu Den-en-toshi Line and Tokyo Metro Hanzomon Line inter-running services; they were not capable of running through onto the Tobu Skytree Line, and had circular "K" stickers on the centre front cab window to indicate this.[2]

Design

Based on the earlier Tokyu 9000 series EMU design, two sets were introduced in 1992, followed by a third in 1993.[2] 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.[2] All three sets have since been modified with full-colour LED destination indicators.[2]

Oimachi Line transfer and reclassification

Set 2103 was the first set to be transferred to the Oimachi Line; it was introduced on the line in 2018 as a 5-car formation.[5] By February 2019, 2000 series sets 2102 and 2103 were in service on the Oimachi Line, with set 2102 being shortened to a 5-car formation as well; they were reclassified "9020 series" and respectively numbered 9022 and 9023.[5]

Set 2101 was transferred to the Oimachi Line in March 2019; like the other sets, it was shortened to 5 cars and was renumbered 9021.[1]

Fifteen surplus cars were scrapped in 2018.[1]
