The Tokyo Metro 08 series (東京メトロ08系, Tōkyō Metoro 08-kei) is an electric multiple unit (EMU) train type operated on the Tokyo Metro Hanzōmon Line in Tokyo, Japan since 2003. Introduced into service on 7 January 2003, a total of six ten-car trainsets were manufactured by Nippon Sharyo between 2002 and 2003 to augment the 8000 series trains following the extension to Oshiage.[2]

Description

The Tokyo Metro 08 series was introduced into service on 7 January 2003 to increase capacity on the Hanzomon Line, ahead of its extension from Suitengumae to Oshiage in March of that year.[3][1] The train type is also used on through services to the Tokyu Den-en-toshi Line and the Tobu Isesaki and Nikko Lines.[1] The 08 series was the last new rolling stock type purchased by TRTA before it was privatised the following year.[4]
