[1] Cars are 18 metres (59 ft 1 in) long (leading cars are 54 centimetres (1 ft 9 in) longer [2]), 2,760 millimetres (9 ft 1 in) wide, [1] and approximately 3.5 metres (11 ft 6 in) tall.

History
On 13 December 2021, the Yokohama Municipal Subway announced that new trainsets would be purchased for the Blue Line, replacing the oldest 3000A series trainsets dating back to 1992. [4]
The order was originally made in 2018 for a new batch of 3000V series trainsets but that plan was abandoned in favour of newer 4000 series cars. [5]
As of 3 April 2022 [update], five trainsets (30 vehicles) are to be commissioned in 2022 while the remaining three sets (18 vehicles) will enter service in 2023. [3]
The first trainset entered service on 2 May 2022. [6]
