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.[3] 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[4] and Tokyu Oimachi Line[5] respectively.

Design

[edit]

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.[6] The styling of the trains was overseen by Tanseisha, a company involved in designing commercial buildings along the Tokyu route.[3]

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.[3]

Variants

[edit]
  •   2020 series: 10-car sets used on the Tokyu Den-en-toshi Line since March 2018

On 26 March 2019, Tokyu Corporation announced the introduction of new 3020 series trains on their Meguro Line.[4] The first set of eight cars was delivered in April 2019.[14] A second set of eight cars was transferred from J-TREC in Yokohama to Nagatsuta in May 2019.[15] Trial runs on the Den-en-toshi Line began in June 2019.[16]

The first 3020 series set entered revenue service on 22 November 2019.[17]

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.[18] Finally on 13 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.[19] 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

[edit]

Passenger accommodation consists of high-back seating.[4] The trains are also fitted with security cameras and air purifiers.[20]

Formation

[edit]

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.[4][21] 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:[2]

Details of the 6020 series were officially announced on 12 October 2017.[5] The first set was delivered from the J-TREC factory in Yokohama in December 2017,[24] followed by a second in January 2018.

The first sets entered service on 28 March 2018.[9]

In both sets, car 3 was replaced by a new-build "Q Seat" car built in October 2018. The outgoing cars were subsequently used in 2020 series sets 2126 and 2127.[11] The Q Seat cars are usually arranged in longitudinal mode, but on specific evening express trains from Ōimachi to Nagatsuta, they are arranged in transverse mode and can be used only with a reservation by paying a small surcharge.[23]

On 28 February 2025, Tokyu announced its plans to procure eighteen 5-car 6020 series sets to replace all 9000 and 9020 series sets on local Ōimachi Line services.[25] The first such set, 6151, was delivered to the Nagatsuta depot in March of that year.[26]

Interior

[edit]

Passenger accommodation consists of high-back longitudinal seating throughout,[5] except car 3, which is a "Q Seat" car that features rotating pairs of seats that can be arranged in longitudinal mode or transverse mode.[23] Security cameras are installed in the cars.[5]
