History

The prototype two-car set at Magome Depot in May 1989
Set 12-005 with painted aluminium body, November 2007

Two prototype cars, numbered 12-001 and 12-002, were delivered from Tokyu Car Corporation in April 1986. These cars had stainless steel bodies and were originally built with conventional traction motors. The cars were converted to linear motor propulsion in 1987, with testing conducted on a special test track at Magome Depot. Following successful testing, it was announced in December 1988 that linear motor propulsion would be used for the new Toei Ōedo Line (then Line 12) under construction in Tokyo.

The first production trains were delivered as 6-car sets from Nippon Sharyo to Hikarigaoka Depot from September 1990 for testing on the line between Hikarigaoka and Nerima before entering revenue service in December 1991.[5]

A total of 424 vehicles were subsequently built by Nippon Sharyo and Hitachi up until 2001, formed as 53 8-car sets. The production trains featured aluminium bodies, and the first six sets were painted.[1][5]

The first 6th-batch 12-600 series set (cars 12-611 to 12-618) was delivered from the Kawasaki Heavy Industries factory in Hyōgo Prefecture in August 2011.[6] It entered service on 23 February 2012.[7] On 30 March 2015, Toei Subway announced it had ordered a second batch of 12-600 series trains. The magenta stripe will be located at the height of the windows so it can be seen above the platform edge doors installed at every station. There will be LCD information displays above the doors. The trains will enter service on 6 April 2015, with six units scheduled to be delivered by June 2016, replacing older 12-000 series trains.[8][9]
