12-600 series
12-600 series set 12-611 in March 2012

A new batch of sets, classified 12-600 series, were delivered from fiscal 2011. Broadly based on the earlier 4th-batch design (sets 16 to 53), these sets included a number of design improvements.[2] The latest batch of sets entered service on 15 February 2019 and use a different headlamp setup, with a dual headlamp-taillamp fixture; as opposed to shield-beam headlamps as used on the first eight sets, these use LED fixtures.

As of 2018, ten sets are in service and are all based at Kiba Depot.

History
The prototype two-car set at Magome Depot in May 1989
First-batch set 05 with painted aluminium body in 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 six-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.[6]

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][6]

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.[7] It entered service on 23 February 2012.[8] On 30 March 2015, Toei Subway announced it had ordered a second batch of 12-600 series trains. On these trains, the magenta stripe is located at the height of the windows so it can be seen above the platform edge doors installed at every station. LCD information displays are provided above the doors. The trains entered service on 6 April 2015, with six units to be delivered by June 2016, replacing older 12-000 series trains.[9][10]

The last remaining first-batch trains (sets 01 to 06) are scheduled to be withdrawn by the end of June 2016.[11]

Preserved examples
Preserved prototype car 12-001 at Chihaya Flower Park in Toshima, Tokyo, June 2008

The two prototype cars, 12-001 and 12-002 are preserved at Chihaya Flower Park in Toshima, Tokyo.[12]

  • Linear motor as used on the 12-000 series
  • T-12D bogie as used on the Toei 12-000 series. Note the low height of the bogie enabled by the use of linear motors.
  • A 12-000 series EMU (left) and a class E5000 electric locomotive (right). The class E5000 locomotive is used to haul 12-000 series units to Magome depot for major overhauls.
