Tokyu 2020 series

The Tokyu 2020 series (東急2020系, Tōkyū 2020-kei) is an electric multiple unit (EMU) commuter train type 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.

A Den-en-toshi Line 2020 series set in August 2021

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 are to be held and in which Tokyu celebrates its 100th anniversary.[1]
