we recommend taking the Airport Express (AREX). AREX is the fastest and most convenient option for transit passengers to explore Seoul at their own time and pace.
The AREX railway connects Incheon International Airport to Seoul Station. There are two types of trains: non-stop express trains and commuter trains. The airport line shortens the travel time between Incheon Airport and Seoul Station to just 43 minutes for the non-stop express trains and 53 minutes for commuter trains. The express train departs Seoul Station every 30 minutes. The commuter train departs Geomam Station every 6 minutes and Incheon International Airport every 10 to 12 minutes.
