The Yokohama Municipal Subway 10000 series (横浜市交通局10000形) is a linear motor-powered electric multiple unit (EMU) operated by the Yokohama Municipal Subway on the Green Line since March 2008.
As of 1 April 2017[update], the fleet consists of 17 four-car sets with all cars motored, and formed as shown below with car 1 at the Nakayama end.[3] The sets are designed to allow the insertion of two centre cars at a later date, hence the numbering sequence that omits cars 3 and 4.

History
The first two pre-production sets, 10011 and 10021 were completed in May 2007 and shipped to Yokohama, arriving in June. The first full-production set, 10031, was delivered in July 2007, being hauled via JR tracks from the Kawasaki factory in Hyōgo Prefecture. The full-production sets feature a number of minor design improvements, including green-coloured gradations externally instead of the blue gradations used on the first two sets.
The trains entered service from 30 March 2008 with the opening of the Green Line.[3]
Two second-batch four-car sets were introduced from the start of the revised timetable on 29 March 2014.[5] These sets feature LED headlights, full-colour LED destination indicators, interior LED lighting, and 17-inch (430 mm) LCD passenger information displays.[5]
