The E259 series (E259系) is a DC electric multiple unit (EMU) train type operated by East Japan Railway Company (JR East) in Japan since October 2009 on Narita Express limited express services to and from Narita International Airport.[4]

Design

The design of the trains was overseen by industrial designer Kenji Ekuan.[5] Retracting gangway connections on the end cars allow two sets to be coupled together to form 12-car formations. Electrical and safety equipment is duplicated, as on the E233 series commuter trains, to improve safety and reliability. Active suspension on end cars and yaw dampers between all cars for improved ride comfort.[1] The MoHa E259-500 car is equipped with two pantographs, but one is for emergency use.[6]

Unlike the 253 series, the E259 series trains are not equipped with Automatic Train Control (ATC).

Operations

The E259 series trains are used almost exclusively on Narita Express limited express services linking Narita International Airport in Chiba Prefecture with Tokyo and other stations in the Greater Tokyo area. E259 series trains are also used occasionally on seasonal Marine Express Odoriko services between Tokyo and Izukyū-Shimoda. One set, Ne002, is assigned to these services, and carries a logo sticker on the front and sides.[7]

Formation

The fleet consists of 22 six-car sets, consisting of four motored (M) cars and two trailer (T) cars, as shown below, with car 1 at the Tokyo end.[8][9]

Car No. 1/7 2/8 3/9 4/10 5/11 6/12

Numbering KuHa E258 MoHa E258 MoHa E259 MoHa E258-500 MoHa E259-500 KuRo E259
Weight (t) 38.4 38.0 36.5 38.0 37.0 38.9

The "Tsc" cars are green (first class) cars. Cars 3 and 5 are equipped with PS33D single-arm pantographs (two on car 5).[9]

Bogies

The DT77 (motored) and TR262 (trailer) bolsterless bogies are developed from the DT71 and TR255 bogies used on the E233 series EMUs.[10] The end bogies of the Tc driving cars are designated TR262, and the inner bogies of the Tc driving cars are designated TR262A.[10] All the bogies use tread brakes, and the trailer bogies additionally use disc brakes.[10] Wheel diameter is 860 mm, and the distance between wheel centres is 2,100 mm.[10]

Interior accommodation

The passenger compartment floor construction has been improved for reduced interior noise, and the height difference between coach and platform has been reduced by 50 mm compared with the earlier 253 series trains for ease of access.[8] Luggage storage areas feature lockable straps for security, and security cameras are installed in vestibule and luggage areas.[2] Luggage space is also provided beneath the seats. Electric power outlets are provided at each seat.[1]

Four ceiling-mounted passenger information display units are provided in each car. These feature two 17-inch screens on each side, displaying information in four languages (Japanese, English, Korean, and Chinese).[1]
