Tokyu 2020 series/Tokyu 3020 series

The Tokyu 3020 series is a Japanese city commuter electric multiple unit operated by the Tokyu Corporation since November 2019 on the Tokyu Meguro Line.
==History==
The 3020 series sets were designed to aid with the increasing passenger numbers on the Tokyu Meguro Line to supplement the 3000 and 5080 series cars on the line. Two eight-car sets were built by J-TREC at their Niitsu Works in mid-to-late 2019. Operations began on 22 November 2019; as currently all rolling stock on the Meguro Line are six cars long the sets will be used in six-car formations until eight-car service is implemented. The two intermediate cars that would extend the sets to eight cars will be treated as spare cars. A third set, 3123, was built in 2022.
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. 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.
==Design==
The 3020 series cars use a contemporary design featuring a rounded front in the image of a "confused face". The sets were designed to harmonize with the towns and stations alongside the line, with "town development" taken into consideration. The design of the sets was overseen by design firm Tanseisha.
==Specifications==
Construction of the cars is of an aluminum alloy based on J-TREC's sustina concept. The sets are based on the Tokyu 2020 series which are in turn based on the JR East E235 series cars and thus share many mechanicals. The sets use 2-level Mitsubishi pure silicon carbide-based MOSFET variable frequency drive traction systems which produce a hissing noise.
