Passenger accommodation consists of longitudinal seating throughout; each seat has a per-occupant width of 46 centimetres (18 in), a 1 cm (0.39 in) increase over those of the 211 series. Wheelchair spaces are provided in every car.[6] Also featured are LCD passenger information displays and security cameras.[6][7] Priority seating areas use a different floor design and color scheme to distinguish them from general-use seating.[6]
