The E257 series (E257系?) is a DC electric multiple unit (EMU) train type operated in Japan by East Japan Railway Company (JR East) and built jointly by Hitachi, Kinki Sharyo, and Tokyu Car Corporation.

Variants

Two variants exist: the original E257-0 series for use on Chūō Main Line Azusa and Kaiji limited-express services, and the E257-500 series for use on Uchibō Line, Sotobō Line, Sōbu Main Line, Narita Line, and Kashima Line limited-express services.[1]

E257-0 series

This sub-series version was introduced on 1 December 2001, to replace the aging 183 and 189 series rolling stock on Chuo Main Line Azusa and Kaiji services. Based at Matsumoto depot, the fleet consists of sixteen 9-car sets (M101 to M116) with a full cab at the Matsumoto end and a gangwayed cab at the Tokyo end, and five 2-car "add-on" sets (M201 to M205) with a full cab at the Tokyo end and a shunting cab only at the Matsumoto end.

The type was the recipient of the 45th Blue Ribbon Award (2002) of the Japan Railfan Club.

Operations

Matsumoto-based E257 series trains were also used on the Ohayō Liner Shinjuku and Home Liner Odawara commuter services running on the Tokaido Main Line until 14 March 2008.

From 2016, the E257 series trains are scheduled to be replaced by new EMUs on Chuo Line limited express services and redeployed on other services, possibly Odoriko services.[2]
