The 253 series is a DC electric multiple unit train type operated by East Japan Railway Company. 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 The 253 series trains were withdrawn from Narita Express services on 30 June 2010, with two trains redeployed on Nikkō and Kinugawa limited express services from June 2011.
Design
The design was overseen by industrial designerKenji 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 were manufactured in 1990 and entered service in 1991. The types of coaches were the KuRo 253, MoHa 253 and KuMoHa 252 coaches. Three-car sets were sometimes joined together to form six-car formations.
2nd-4th batches
36 coaches were manufactured in 1992 to 1996 to cope with an increase in passenger traffic on the Narita Express, eventually enabling the 253 series trains to run in 12-car formations as well as the older 3/6-car formations. Minor changes were observed in the interior, notably that the seats had two colours, black and red.
5th batch
The fifth batch of 253 series trains consisting of two six-car sets, Ne201 and Ne202, were delivered from Tokyu Car in 2002 in anticipation of the 2002 FIFA World Cup which was expected to further increase passenger traffic on the Narita Express. Variable frequency traction systems were built into these trains, and they were fitted with DT69 and TR254 bogies. The interior differed from previous batches, with LED destination indicators, conventional rotating seats in standard class, and 2+1 seating in Green cars.

Interior
The standard-class seating arrangement used in the original 253 series sets was unusual for Japanese limited express trains in consisting of European-style fixed four-seat bays. The seats were later rearranged in a fixed unidirectional layout facing four-seat bays in the centre of each car between 2003 and 2004. The green cars in the original three-car sets were classified as KuRo 253 or KuRo 253-100. The KuRo 253 cars had ten rows of 1+1 seating at a seat pitch of, with seats angled to face the windows, together with one 4-person compartment. The KuRo 253-100 cars had eight rows of seats arranged in a mixture of 2+1 and 1+1 at a seat pitch of, together with one 4-person compartment.
Retirement
The 253 series trains were gradually replaced on Narita Express services from October 2009 by new E259 series EMUs, with the last trains operating until 30 June 2010. Most trains were subsequently withdrawn and scrapped, but two six-car sets, Ne201 and Ne202, were converted in late 2010 to become 253-1000 series, and two three-car sets, Ne107 and Ne108, were sold to the Nagano Electric Railway.
253-1000 series
The two newest-built sets, Ne201 and Ne202, underwent extensive refurbishment at JR East's Omiya Works and Tokyu Car Corporation's Yokohama factory to become 253-1000 series sets OM-N1 and OM-N2 for use on Nikkō and Kinugawa limited express services jointly operated with Tobu Railway from 4 June 2011, replacing the 485 series and 189 series EMUs currently used. Refurbishment includes entirely new interiors with monoclass seating configured with seat pitch increased from 1,020 mm to 1,100 mm, as well as replacement of main equipment. The total seating capacity for each six-car set is 290. Onboard announcements and passenger information displays is in four languages, Japanese, English, Chinese, and Korean.
