The Tokyu 2020 series (東急2020系, Tōkyū 2020-kei) is an electric multiple unit (EMU) commuter train type used by the private railway operator Tokyu Corporation in Japan on the Tokyu Den-en-toshi Line in the Tokyo area since March 2018.[1]
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.[2] 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]
Interior
Passenger accommodation consists of high-back longitudinal seats.[1] In addition to passenger information screens placed above the doorways and car ends, LCD screens are also located above the seats.[1] Security cameras are installed in the cars.[1]
Formation
The trains are formed as follows, with five motored ("M") cars and five non-powered trailer ("T") cars, and car 1 at the Shibuya end.[3]
