The design of the trains was overseen by industrial designer Kenji Ekuan.[4] 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 provide improved ride comfort.[1] The MoHa E259-500 car is equipped with two single-arm pantographs, but one is reserved for emergency use.[5]
Unlike the previous 253 series trains, the E259 series trains are not equipped with Automatic Train Control (ATC).
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.[7][8]

The "Tsc" cars are green (first class) cars. Cars 3 and 5 are equipped with PS33D single-arm pantographs (two on car 5, one on car 3).[8]
Bogies
The DT77 (motored) and TR262 (trailer) bolsterless bogies are developed from the DT71 and TR255 bogies used on the E233 series EMUs.[9] The end bogies of the Tc driving cars are designated TR262, and the inner bogies of the Tc driving cars are designated TR262A.[9] All the bogies use tread brakes, and the trailer bogies additionally use disc brakes.[9] Wheel diameter is 860 mm (33.9 in), and the distance between wheel centers is 2,100 mm (6 ft 11 in).[9]

Interior accommodation
The passenger compartment floor construction has been improved for reduced interior noise, and the height difference between the coach and the platform has been reduced by 50 mm (2.0 in) compared with the earlier 253 series trains for ease of access.[7] 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]
Ordinary class
Ordinary-class cars have 2+2 abreast seating with forward-facing rotating/reclining seats. Seat pitch is 1,030 mm (41 in), compared to 980 mm (39 in) on earlier trains.[1]
Green class
Green (first class) cars have leather-covered forward-facing rotating/reclining seats also arranged in 2+2 configuration. Seat pitch is 1,160 mm (46 in).[1]
History
The first two sets, Ne001 and Ne002, were delivered to Kamakura Depot from Tokyu Car Corporation's Yokohama factory on 23 April 2009, with test running on the Sōbu Main Line commencing the same day.[10]
Nine E259 series sets entered revenue service on Narita Express services from 1 October 2009, with 10 out of 26 return workings daily operated by E259s.[11] By June 2010, they had completely replaced the 253 series EMUs formerly used on Narita Express services.[7]
In March 2023, JR East announced that it would introduce a new design to existing E259 series sets. The updated livery will retain the black and red color pallet but will feature silver accents at the front as well as the phrase "SERIES E259" being plastered along the exterior.[12] As of 17 March 2024, repainting for the entire E259 series fleet was completed with the last set, Ne022, having received the new livery.[13]

In December 2023, JR East announced that some E259 series sets will be used on most Shiosai limited express services from the start of the revised timetable on 16 March 2024, replacing the older 255 series EMUs used on these services.[14]
