Design

The trains are manufactured by Hitachi with aluminium bodies to its "A-train" concept.

The 10000 series is the first new model to be built for Tokyo Metro following privatization. The front-end design is intended to evoke the appearance of the 300 series trains, which were the first trains used on the Marunouchi Line. [ [http://journal.mycom.co.jp/news/2006/10/02/320.html "東京メトロ、民営化後初の新型車両「10000系」を車両基地で一般公開", 2 October 2006] ] The train whistles also use the same type as the old train used on the Ginza Line.

On set numbers 10105 onward, built from 2007, the gold colour line was omitted on the front ends.

Lines

The fleet of 10-car sets currently operate on the Yūrakuchō and Fukutoshin lines, including inter-running services over the Tōbu Tōjō Line between Wakōshi Station and Shinrinkōen Station, and also services over the Seibu Yūrakuchō and Ikebukuro Lines between Kotake-mukaihara Station and Hannō Station.

The trains are designed to allow two intermediate cars (cars 4 and 5) to be removed easily to create 8-car sets when through-running commences from the Fukutoshin Line to the Tōkyū Tōyoko Line in 2012. Five sets (10101 to 10105) were reformed as 8-car sets from the start of Fukutoshin Line services in June 2008 to cover for a shortage in 8-car 7000 series trainsets. These sets are identified by the addition of "8 CARS" stickers on the cab windows. ["Japan Railfan Magazine", September 2008 issue, p.62-63]

History

The first set was delivered in May 2006, and entered service on the Yūrakuchō Line and Tōbu Line in September 2006. 10000 series sets entered service on the Seibu Line in February 2007.

At the start of Fukutoshin Line services in June 2008, a total of 22 sets had been delivered. ["Tetsudō Daiya Jōhō" magazine, July 2008 issue, p.39]
