# Toei 10-000 series

The Toei 10-000 series (都営10-000形, Toei 10-000-gata) was an electric multiple unit (EMU) train type operated by the Tokyo subway operator Tokyo Metropolitan Bureau of Transportation (Toei) on the Toei Shinjuku Line in Tokyo, Japan, from 1978 until 2018.

## Operations

The 10-000 series operated on the Toei Shinjuku Line between Shinjuku and Motoyawata, and also on inter-running services over the Keio Line from Shinjuku as far as Hashimoto on the Keio Sagamihara Line.

## Formations

By April 2017, the fleet consisted of five eight-car sets (sets 10-240 to 10-280) with six motored (M) cars and two trailer (T) cars, formed as shown below, with car 1 at the Shinjuku end.
| Car No. | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
| Designation | Tc2 | M2' | M1 | M2 | M1 | M2 | M1 | Tc1 |
| Numbering | 10-xx9 | 10-xx8 | 10-xx7 | 10-xx6 | 10-xx5 | 10-xx2 | 10-xx1 | 10-xx0 |
* "xx" corresponds to the set number.
* Cars 3 and 7 were each fitted with two lozenge-type pantographs, and car 5 was fitted with one.

## Interior

Passenger accommodation consisted of longitudinal bench seating throughout. Wheelchair spaces were added when the original six-car sets were lengthened to eight-car sets.

## History

The prototype set, 10-010, was built in 1971, and initially tested on the Toei Mita Line.
Refurbishment commenced in fiscal 2009. This consisted of adding external speakers, replacing the original roller blind destination indicators with LED indicators, moving the body side destination indicators from the ends to a central position, and adding interior passenger information displays.
In 2005 and 2006, the 10-xx7 and 10-xx8 cars of sets 10-010 to 10-180 were refurbished and reformed with new driving cars to become 10-300R series. These cars were built between 1986 and 1989 as batches 3 and 5 to lengthen original 6-car sets to 8 cars, and so were still relatively new compared to the rest of the cars in the sets in which they were contained.
The final set, 10-280, was retired on 11 February 2018.
