The AREX Class 2000 [1] is an electric multiple unit of the Airport Railroad operated by the Incheon International Airport Railroad on the AREX service. It is used to make the slower local journeys and hence has a more metro like layout with 4 doors per side and longitudinal seating, in contrast to the express layout the 1000s have.
On September 15, 2025, the first of nine second generation 2000 series trains began revenue service on the all-stop service. [2] The trains feature a redesigned exterior and interior and a top operating speed of 150 km/h (93 mph). Two more sets are expected to enter service by October 17 with the remaining six entering service by the end of the year. [2]
