The 209 series (209系?) is a commuter electric multiple unit (EMU) train type operated by East Japan Railway Company (JR East) in the Tokyo area of Japan since 1993.
The series was introduced in 1993 to replace the aging 103 series stock on the Keihin-Tōhoku and Negishi lines. The concept of the 209 series was to create a low-cost, minimal lifespan train (approximately 15 years) that would be replaced rather than rebuilt when they became life-expired.
The 209 series was the first of the "New series trains" (新系列電車 Shin-keiretsu densha?), and served as the basis for the E501, E217, 701, and E127 series rolling stock, as well as the E231 series stock, which in turn became the blueprint for successive trains developed by JR East and other railway companies in Japan.
The original full-production version introduced on both the Keihin-Tōhoku (10-car sets) and Nambu (6-car sets) lines in 1993. 6-door SaHa 208 cars were inserted into the Keihin-Tōhoku Line sets in 1995.
The 209 series trains on the Keihin-Tōhoku/Negishi lines were replaced by new E233 series trains from autumn 2007, with the last sets withdrawn by 24 January 2010. A large number of these units were subsequently rebuilt as 209-2000/2100 series four- and six-car sets for use in the Chiba area.
