AREX - Rolling Stock

Rolling Stock

AREX operates two types of trains, one for commuter and one for express services, both supplied by Hyundai Rotem. Three 1000 series express trains and nine 2000 series commuter trains were delivered for phase 1 of the project, and original plans foresaw a doubling of their numbers for the second phase.

Both trains are six-car electric multiple units, which can be expanded to eight cars in the future. End cars and the fourth car are trailers, the second, third and fifth car are powered. The trains have a design speed of 120 km/h (75 mph), but are operated at a maximum 110 km/h (68 mph) on surface tracks and a maximum 100 km/h (62 mph) in tunnels. Each car has a length of 19.95 m (65.5 ft) and a width of 3.12 m (10.2 ft), with a carbody made of aluminum. The commuter version has four pairs of sliding doors on each side of each car, the express version has two pairs of sliding doors on each side of each car.

Express trains have 272 comfortable seats with armrests in 2+2 configuration, overhead luggage shelves and additional luggage racks. Passenger compartments are separated from door areas and from transitions between cars by transparent sliding doors. Commuter trains are similar to subway trains with seats along the walls and do not have overhead shelves, offering seating for 282 passengers and standing room for 630 passengers. There are no separating doors, transitions between cars are open. Both train types offer disabled seats and are equipped with LCD screens for passenger information, including flight arrivals and departures.
