The Tokyu 2020 series (東急2020系, Tōkyū 2020-kei) is an electric multiple unit (EMU) commuter train type built by J-TREC and used by the Japanese private railway operator Tokyu Corporation in the Tokyo area since March 2018.^[1] The 2020 series is used primarily on the Tokyu Den-en-toshi Line while its derivatives, the 3020 series (3020系, 3020-kei) and the 6020 series (6020系, 6020-kei), are used mainly on the Tokyu Meguro Line^[2] and Tokyu Oimachi Line^[3] respectively.

Design

The 2020 series trains were built by Japan Transport Engineering Company (J-TREC) as part of its "Sustina S24 Series" family of 20-metre long four-door stainless steel cars.^[4] The styling of the trains was overseen by Tanseisha, a company involved in designing commercial buildings along the Tokyu route.^[1]

The classification "2020 series" for the trains was chosen to mark the year 2020 in which the Tokyo Olympics were scheduled to be held and in which Tokyu celebrated its 100th anniversary.^[1]

Variants

On 26 March 2019, Tokyu Corporation announced the introduction of new 3020 series trains on their Meguro Line.^[2] The first set of eight cars was delivered in April 2019.^[12] A second set of eight cars was transferred from J-TREC in Yokohama to Nagatsuta in May 2019.^[13] Trial runs on the Den-en-toshi Line began in June 2019.^[14]

The first 3020 series set entered revenue service on 22 November 2019.^[15]

Set 3123 was the first set to be lengthened to an eight-car formation, having re-entered service in April 2022. Another set 3121 was lengthened to an eight-car formation and re-entered service mid July 2022.^[16] Finally on the 13 of August 2022, the remaining set 3122 was sent to Nagatsuta depot where it was lengthened to an eight-car formation.

Service commenced on the Tōkyū Shin-Yokohama Line in March 2023. As of June 2023, the 3020 series lacks equipment needed in order to through run on the Sōtetsu Shin-Yokohama Line and associated through services. Tokyu plans to install the required equipment to enable Sotetsu through service in the near future.^[17] Set 3121 had officially entered service along the Sotetsu network on September 26, 2023, over a half year later of the opening of the Sōtetsu-Tokyu Link Line.

Interior

Passenger accommodation consists of high-back seating.^[2] The trains are also fitted with security cameras and air purifiers.^[18]

Formation

The trains are operated as eight-car sets. They were originally built as such, but were initially operated as six-car sets, with two cars per set stored until 2022, when platform doors were extended to fit 8-car trains as part of Tokyu Corporation's strategy to cope with high demand on the Meguro Line and for the opening of the Sōtetsu Tōkyū Link Line.^[2][19] All three trainsets are distinguished with an “8-Cars” sticker located on the front window of the first and last cars, and are formed as follows:
