Incheon International Airport Train Transfers

There is a station for the Airport Railroad Express (AREX, also written as A'REX) in the Transport Centre, just next to Terminal 1. Terminal 2's basement is where you'll find it.

It links Gimpo Airport and Seoul with the rest of the world. Connectivity to the Incheon Subway, the Seoul Metropolitan Subway, and the Incheon Airport Maglev can be found at several stations along the route.

Check-in and immigration services are available to departing travelers at the Seoul Station City Airport Terminal.

At the same terminal as AREX, but on a different platform, ran the Korea Train eXpress (KTX). There were 20 departures daily, 12 on the Gyeonbu Line, 2 on the Gyeonjeon Line, 4 on the Honam Line, and 2 on the Jeolla Line.

After launching in 2014, the service was halted in March 2018 owing to poor demand. The line was permanently shut down in September 2018, marking the end of the temporary suspension.

In February 2016, the Incheon Airport Maglev began service. From the airport, riders can travel the 6.1 km to the southwest of the island, where a water park is located, via a network of six stations in the first phase.

There will be a 9.7-kilometer extension of the line in the second phase, taking it farther to the northwest of the island. The extra 37.4 kilometers added in Stage 3 will make the route round.

Airport Railroad Express (AREX)

The Airport Railroad Express (AREX) connects Incheon International Airport and Seoul Station in South Korea through Gimpo International Airport.

On March 23, 2007, service began between the two airports, and on December 29, 2010, the line was extended to Seoul Station. High-speed, long-distance Korean Train Express trains began using the line on June 30, 2014, but stopped doing so in March 2018 due to poor ridership.

Two types of commuter services are available: Express and "All Stop" Before the first phase opened, it took 28 minutes for express services and 33 minutes for commuter services to go between Incheon International Airport and Gimpo International Airport.

Now that the second phase of Seoul Incheon International Airport has opened, it only takes 43 minutes to get to Terminal 1 via the airport's half-hourly Express services. With the All Stop service, you can catch a train as often as once every 6 minutes, and the trip will only take 53 minutes. This contrasts the typical journey times of buses (70 minutes) and taxis/private vehicles (60 minutes).

At the Seoul Station City Airport Terminal, located on the western side of Seoul Station, passengers of certain express trains can check in for their flights, have their bags x-rayed, get their exit stamps from a Korean Immigration Service officer, and go through expedited security screening at Incheon.

The AREX line is depicted as a bright blue on Seoul's subway maps, often divided in the middle by an orange stripe. It was initially thought that AREX needed to be connected to the metro system.

Once Korail, the company that runs many of Seoul's subway lines, bought a controlling interest, the commuter line became an integral part of the Seoul Metropolitan Subway. All connections to other metro lines in Seoul and Incheon are now free of charge.
