鉄道車両の座席には、コンセントプラグがついているものがありますか？
The M9s will have numerous customer amenity improvements. The cars will have closed loop seat armrests similar to those on the M8s, wider seats, electrical outlets on both sides of a car in each row of seats, four 32-inch multimedia screens in each car, four to six additional seats per married pair, as well as powered doors on the "B" end of each car. The flip seats in the cars will have suspension systems so they do not slam. There will be exterior destination signs that are visible on each end as the train approaches a station, to let passengers know where the train is going. All M9s will be equipped with positive train control (PTC). The cars will have CCTV cameras, allowing the train crew to view the passenger areas of the train. They will also feature LED displays that show the current station, the following station, and the train's destination, and automated announcements. The cars also have external public address speakers, and electronic destination signs.
