Japanese train type From Wikipedia, the free encyclopedia
The Tokyo Metro 07 series (東京メトロ07系, Tōkyō Metoro 07-kei) is an electric multiple unit (EMU) train type operated by Tokyo Metro in Tokyo, Japan. Introduced into service in 1993, a total of six 10-car sets were manufactured by Kawasaki Heavy Industries and Nippon Sharyo between 1993[verification needed] and 1994 for use on the Tokyo Metro Yūrakuchō Line. From 2006, the sets were permanently transferred to the Tokyo Metro Tōzai Line to replace ageing 5000 series trainsets.

The front ends have an emergency exit. Headlights and taillights are round. Sets are fitted with skirts. These were modified on sets transferred to the Tōzai Line.
The trains originally had a two-handle control system. Tōzai Line sets were modified with a single-handle (left-hand) system on transfer to the Tōzai Line. The Tōzai Line sets have a master controller which incorporates a deadman system which applies the brakes if the master controller is released by the driver.
The first sets (07-101 and 07-102) were introduced in 1992. Four more sets (07-103 to 07-106) were delivered in 1994. The six 10-car sets were initially all based on the Tokyo Metro Yūrakuchō Line, but with the introduction of the 10000 series,[3] between July 2006 and March 2007, four sets (07-103 to 07-106) were transferred to the Tokyo Metro Tōzai Line to replace ageing 5000 series trains, and were repainted into that line's color scheme with light blue waistline stripes.[1] The two remaining Yurakucho Line sets (07-101 and 07-102) were stored out-of-use from October 2007. Set 07-101 was subsequently repainted into the Tōzai Line colours at Shin-Kiba Works, and temporarily reallocated to the Tokyo Metro Chiyoda Line from September until December 2008.[1][4]
Beginning in 2018, the 07 series fleet has undergone a programme of refurbishment, also known as "class B repair".[5] The programme included the installation of LED lighting throughout, full-colour destination displays, and updated door chimes and flooring. The first set to undergo refurbishment (07-103) returned to service on the Tozai Line on 15 August 2018, and on the Chūō-Sōbu and Tōyō Rapid lines on 25 October of that year.[6] Refurbishment of the 07 series has been completed as of May 2022, however, some sets continue to receive new front skirts.[7][8]
