The Tokyo Metro 08 series was introduced into service in 2003 to increase capacity on the Tokyo Metro Hanzomon Line, which was extended from Suitengumae to Oshiage in March 2003.[1] The train type is used on inter-running services via the Hanzomon Line 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.
As of 1 April 2017[update], the fleet consists of six ten-car sets, numbered 51 to 56, formed as shown below, with five motored (M) cars and five trailer (T) cars.[3][4] Car 1 is at the Oshiage end.[1]
