The Toei 12-000 series (東京都交通局12-000形) and the related Toei 12-600 series (東京都交通局12-600形) are electric multiple unit (EMU) train types operated by the Tokyo subway operator Tokyo Metropolitan Bureau of Transportation (Toei) on the Toei Oedo Line in Tokyo, Japan.

Following testing of a two-car prototype in the late 1980s, the 12-000 series was introduced into service in December 1991. A total of 53 eight-car 12-000 series sets were built between 1990 and 2000 by Nippon Sharyo and Hitachi.

The later 12-600 series first entered service in 2012. A total of 19 eight-car sets were built from 2011 by Kawasaki Heavy Industries and Nippon Sharyo.

12-000 series
These are eight-car sets that entered revenue service in December 1991 as the first production trains to be used on the Toei Oedo Line.

Formation

 * Each M1 car is fitted with a lozenge-type pantograph.
 * Car 5 is designated as a mildly-air-conditioned car.

Interior
Passenger accommodation consists of longitudinal seating throughout. Priority seating is provided.

History
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 units 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. A total of 424 vehicles would be 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.

The last remaining first-batch trains (sets 01 to 06) are scheduled to be withdrawn by the end of June 2016.

12-600 series
These are eight-car sets that entered revenue service in 2012. Broadly based on the earlier 4th-batch design (sets 16 to 53), these sets included a number of design improvements.

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

Formation
The 12-600 sets are formed as shown below, with all cars motored.


 * Each M1 car is fitted with a single-arm pantograph.
 * Car 5 is designated as a mildly-air-conditioned car.

History
The first 12-600 series set (cars 12-611 to 12-618) was delivered from the Kawasaki Heavy Industries factory in Hyōgo Prefecture in August 2011. It entered service on 23 February 2012.

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.

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.
