Design
editThe trains have lightweight stainless steel car bodies. The car bodies were designed using computer analysis while maintaining the necessary strength. Compared to the preceding 8000 series trains, these trains weigh approximately 2 tons lighter per car.[1][2] Tokyu operated the 8090 series as five- and eight-car sets, with three and six motored cars per trainset.[3] The 8590 series cab cars have emergency exit doors in the front to permit operation on underground lines.[4]

History
editThe 8090 series were introduced on the Tokyu Toyoko Line in 1980.[4]

8090 series on the Toyoko line in August 1988
In preparation for future inter-running services between the Toyoko Line and the then-finalised Minatomirai Line, reorganisation of this series took place from September 1988 to February 1989. This was done by manufacturing 10 new 8590 series cab cars with emergency exit doors and removing three cars from each of the ten 8090 series sets and combining two sets of the extracted cars with two of the newly-built 8590 series end cars, thus forming 5 8590 series 8-car sets. In addition, the original 8090 series sets became 5-car sets and were transferred to the Tokyu Oimachi Line.[4][5]
In 2006, sets 8694 and 8695 were lengthened to 10 cars and transferred to the Tokyu Den-en-toshi Line while sets 8691-8693 were re-deployed to the Oimachi Line as five-car sets.[6]
The 10-car sets were used on Tokyu Den-en-toshi Line and Tokyo Metro Hanzomon Line inter-running services, but they were not capable of running through to the Tobu Skytree Line. Hence, they had "K" stickers attached on the front cab window to indicate this.[7]

Withdrawal
editFrom 1 May 2013, sets 8081 and 8099, which were the last two 8090 series sets on the Oimachi Line received farewell headmarks on the cab fronts just before their retirement.[8]

On 11 December 2018, 10-car set 8695 was withdrawn from service on the Den-en-toshi Line.[9] On 27 February 2019, set 8694, which was the last remaining 8590 series set, ended service on the Den-en-toshi Line and was later sent to Onda factory.[10]

Toyama Chihō Railway
editToyama Chihō Railway operates a number of former Tokyu 8590 series trains, classified as 17480 series (17480形). They first entered service on 2 November 2013 and were put into regular operation from 3 November that same year.[13][14] The first 5 cars (DeHa 8592+DeHa 8692, DeHa 8593+DeHa 8693 and DeHa 8191) were transferred to Toyama Chihō Railway in July 2013.[15] Four more cars (DeHa 8594+DeHa 8694 and DeHa 8595+DeHa 8695) followed suit in October 2019.[16]
