Formation

As of 1 April 2017, the fleet consists of 17 four-car sets with all cars motored, and formed as shown below with car 1 at the Nakayama end.[1] 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.[1]

Two second-batch four-car sets were introduced from the start of the revised timetable on 29 March 2014.[3] These sets feature LED headlights, full-colour LED destination indicators, interior LED lighting, and 17-inch LCD passenger information displays.[3]

Future plans

In 2018, it was announced that ten of the 17 sets in operation would be lengthened to six cars each by 2024 as a measure to ease overcrowding on the Green Line.[4]

Special liveries

From 25 February 2018, set 10161 began operating in a special cream and green vinyl wrapping livery based on the livery carried by former Yokohama city tramcars to mark the tenth anniversary of the opening of the Green Line.[5]
