Tokyu 2020, 3020 and 6020 series

Data (as of 21 Dec 2024)

History

There are three types but essentially the same. The 2020 series is for Den-en-toshi Line and formed of ten coaches, the 3020 series is for Meguro Line with eight coaches, and the 6020 series is for Oimachi Line with seven coaches. The first two types are also used for through-services towards underground lines in Tokyo.

The 2020 series was first introduced to Den-en-toshi Line in 2018, not only to replace 8500 series but also to prepare for the 2020 Summer Olympics in Tokyo and the 100th anniversary of Tokyu (established in 1922). Despite the appearance, the 2020 series is based on JR East E235 series to reduce costs of production. Needless to say, the 2020 series was designed for through-services to Tokyo Metro Hanzomon Line and Tobu lines.

In the same year, Tokyu introduced two units of the 6020 series, to increase capacity of express services on Oimachi Line. However, just two days before they entered passenger service, Tokyu announced that it would insert "Q Seat" carriage, an all-reserved coach with transverse seating for commuters. Each trainset was rearranged to six standard coaches and one "Q Seat" carriage just seven months after the introduction, and redundant standard coaches were inserted to the 2020 series units.

In 2019, three 3020 series units were delivered to Meguro Line. They were initially formed of six coaches, but two intermediate coaches were inserted by 2022. They have been used for through-services to Tokyo Metro Namboku, Saitama Railway and Toei Mita Lines, but they do not run Sotetsu lines.

Current Operations & Future Prospects

To sum up, the 2020 series are used for Den-en-toshi, Hanzomon, Tobu Nikko and Isesaki Lines (Chūō-rinkan - Minami-kurihashi or Kuki). The 3020 series are used for Meguro and Shin-Yokohama Lines as well as Tokyo Namboku, Saitama Railway and Mita Lines. The 6020 series are used for express services on Oimachi and Den-en-toshi Lines.

The 3020 series is due to enter Sotetsu lines in August 2023 when all units have Sotetsu's communication devices installed.
