User:XtraJovial/sandbox/Tokyu 2000 series update

The Tokyu 2000 series (東急2000系) 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.

10-car Tokyu Den-en-toshi Line sets
The 2000 series were initially formed as 10-car sets, consisting of six motored (M) cars and four unpowered trailer (T) cars, formed as shown below, with car 1 at the Shibuya end.

The M1 cars are each fitted with one lozenge type pantograph.

5-car Tokyu Oimachi Line sets
In 2018, set 2003 was shortened to a five-car formation, consisting of three motored (M) cars and two unpowered trailer (T) cars. Car 1 is at the Ōimachi end.

From 2019, all three sets were respectively numbered to 9021–9023, from 2001–2003.

The M and M1 cars are each fitted with two single-arm pantographs.

Interior
Seating is longitudinal bench seating throughout. Cars 3 and 9 have wheelchair spaces.

History
The first two sets entered service on the Den-en-toshi Line in September 1992.

Set 2003 entered service on the Ōimachi Line in October 2018 as a five-car set formation.
