The Tokyu 7700 series (東急7700系, Tōkyū 7700-kei) was an electric multiple unit (EMU) train type operated by the private railway operator Tokyu Corporation on the Tokyu Ikegami and Tokyu Tamagawa lines in Japan from 1987 to 2018.[1]

Design
The 7700 series trains were formed between 1987 and 1990 using the bodies of former Tokyu 7000 series trains dating from the 1960s, which were modernized with air-conditioning and mated with new bogies and variable-frequency motor drives.[1] Cars were 18 metres (59 ft 1 in) long and had three pairs of doors per side.[1]
Operations
The trains were formed as three-car sets and used on the Tokyu Ikegami Line and Tokyu Tamagawa Line.[1]
Formations
The fleet consisted of 15 three-car sets, formed as follows, with two motored ("M") cars and one non-powered trailer ("T") car, and car 1 at the Gotanda/Tamagawa end.[2]
Cars 2 and 3 were each fitted with one lozenge-type pantograph.[2]
Interior
Passenger accommodation consisted of longitudinal seating throughout, with a mixture of brown and orange seat moquette.[1]

History
The 7700 series trains sets were initially formed as two- and four-car sets; however, the fleet was subsequently reformed into three-car sets.[1] Set 7915 was formed in 1996 from three former intermediate cars, and had newly-added cab ends of the same design as the Tokyu 1000 series and Tokyu 9000 series trains.[1] This set was withdrawn in 2010.[1]

Withdrawal and resale
Withdrawals commenced in 2000, with six end cars being resold to the Towada Kankō Electric Railway in Aomori Prefecture.[1] While these three two-car sets retained the "7700 series" classification, they were renumbered 7701+7901 to 7703+7903, irrespective of their original car numbers.[3] The 7700 series sets were completely retired on 24 November 2018.[4]
Yōrō Railway
On 21 August 2018, the Yōrō Railway announced its plans to procure fifteen 7700 series cars to replace nearly half of its 31-vehicle fleet, forming three 3-car sets and three 2-car sets.[5] As part of their transfer, the trains received fareboxes and additional wheelchair spaces, as well as transverse seating bays in the intermediate cars of some 3-car sets.[6][7] They carry running numbers between TQ01 and TQ14, based on the cars' original numbers.[8]
The Yōrō Railway originally intended to introduce the trains into service in February 2019;[7] however, their introduction was deferred to 27 April 2019, coinciding with the 100th anniversary of the line's completion.[9]
