Design
editOriginally introduced to the Midosuji Line as 8-car sets, trains were lengthened to 9 cars by 1987,[1] and eventually 10 cars by 1995.[2][1]
Refurbishment
editRefurbishment of the 10 series trainsets began in 1998. Ten trainsets were upgraded to use Variable-frequency drive (VVVF) technology, increasing efficiency.[2]
Interior
editThe 10 series were among the first trains powered by a third rail to be equipped with an air conditioning system.[3]

History
editThe 10 series were the main rolling stock on the Midōsuji Line since 1976.[4]
By 1989, the fleet had reached 234 cars, including the prototype cars that initially operated on the Tanimachi Line.[1]
Retirement of the 10 series began with the introduction of 30000 series trainsets on the Midōsuji Line in 2011.[2] The last trainset retaining its original chopper motors (1113) was retired on 9 July 2020.[5] As of June 2022, one trainset remained in operation.[2] The remaining trainset (1126)[6] was withdrawn from service in July 2022.[7]
