Variants
- E257-0 series: Chūō Main Line
- E257-500 series: Boso Express
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.
