The 253 series (253系?) is a DC electric multiple unit (EMU) train type operated by East Japan Railway Company (JR East). It was introduced on 19 March 1991 for use exclusively on the Narita Express, a limited express service linking Narita International Airport with stations in the Tokyo area. The 253 series trains were withdrawn from Narita Express services on 30 June 2010, with two trains redeployed on Nikkō and Kinugawa limited express services from June 2011.
The design was overseen by industrial designer Kenji Ekuan, and the trains were manufactured by Kinki Sharyo and Tokyu Car Corporation. Sets were formed as three-car and six-car units, running as up to 12-car formations in service. From 1 October 2009, all three-car sets were removed from Narita Express operations.
It was the recipient of the 32nd Laurel Prize of the Japan Railfan Club. Extra sets were built in 2002 to cope with the increase in traffic during the 2002 FIFA World Cup. These sets were classified 253-200 series, and included minor improvements over the original 253-0 and 253-100 series sets, such as LED destination indicators, conventional rotating seats in standard class, and 2+1 seating in Green Cars.
63 coaches (21 trains in three-car formation) were manufactured in 1990 and entered service in 1991. The types of coaches were the KuRo 253 (Green Car driving trailer), MoHa 253 (trailer) and KuMoHa 252 (driving trailer) coaches. Three-car sets were sometimes joined together to form six-car formations.
