The "Tsc" cars are green (first class) cars. Cars 3 and 5 are equipped with PS33D single-arm pantographs (two on car 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. The MoHa E259-500 car is equipped with two pantographs, but one is for emergency use.
Unlike the 253 series, the E259 series trains are not equipped with Automatic Train Control (ATC).
The DT77 (motored) and TR262 (trailer) bolsterless bogies are developed from the DT71 and TR255 bogies used on the E233 series EMUs. The end bogies of the Tc driving cars are designated TR262, and the inner bogies of the Tc driving cars are designated TR262A. All the bogies use tread brakes, and the trailer bogies additionally use disc brakes. Wheel diameter is 860 mm, and the distance between wheel centres is 2,100 mm.
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. Luggage storage areas feature lockable straps for security, and security cameras are installed in vestibule and luggage areas. Luggage space is also provided beneath the seats. Electric power outlets are provided at each seat.
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).
Standard-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.
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).
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.
