AREX Train 2026 Guide: Timetable, Fares & Routes

Arriving at Incheon Airport and wondering how to get to Seoul? AREX is one of the easiest ways to travel between Incheon Airport and central Seoul especially if you want to avoid road traffic.

AREX, or Airport Railroad Express has two services: the Express Train, which runs directly between Incheon Airport and Seoul Station, and the All-Stop-Train, which stops at stations such as Hongik University and Gimpo Airport.

For Singapore travellers, knowing the difference is important. If your hotel is around Hongdae, the All-Stop Train is the one to look for but if heading to Seoul, you can choose between the faster Express Train and the cheaper All-Stop Train.

Here is everything you need to know about the AREX timetable, stations, fares and how to take AREX from Incheon Airport.

What is AREX?

AREX, short for Airport Railroad Express, is a railway service connecting Incheon International Airport with Seoul. It is one of the most convenient ways for travellers to get from the airport to the city without dealing with road traffic.

AREX operates two services: the Express Train and the All-Stop Train. The Express Train runs directly between Incheon Airport and Seoul Station, while the All-Stop Train serves several stations along the route.

Popular stops include Hongik University Station for Hongdae and Gongdeok Station. The Express Train takes about 43 minutes from Terminal 1 to Seoul Station, while the All-Stop Train takes around 59 minutes.

For Singapore travellers visiting Seoul, AREX is a useful option to consider when planning your airport transfer.

AREX Timetable at a Glance

There are two types of AREX trains:

The Express Train has reserved seating and only stops at Seoul Station, Incheon Airport Terminal 1 and Terminal 2. The All-Stop Train operates like a regular airport railway service and stops at the intermediate stations.

AREX Route and Main Stations

The AREX line runs between Seoul Station and Incheon Airport Terminal 2, with Terminal 1 and several Seoul area stations in between.

The main stations are:

The All-Stop Train serves all of these stations, while the Express Train only stops at Seoul Station, Terminal 1 and Terminal 2.

How to Take AREX From Incheon Airport

Taking AREX for the first time is fairly straightforward.

1. Follow the AREX signs

After collecting your luggage and clearing immigration, follow the signs for Airport Railroad / AREX towards the Transportation Center.

The AREX airport stations are located at the transportation centres of Terminal 1 and Terminal 2.

2. Choose your train

Look for signs showing:

• Express Train
• All-Stop Train

Don't accidentally board the wrong service. The Express requires a separate AREX ticket, while the All-Stop Train works with the regular transportation-card system.

3. Buy your ticket

For the Express Train, purchase an AREX ticket before boarding.

For the All-Stop Train, you can use a suitable transportation card or purchase a single-use transportation card at the station.

4. Check the destination station

If you are going to Seoul Station, both train types can take you there.

If you are staying in Hongdae, Gongdeok or another intermediate area, choose the All-Stop Train.

5. Keep your ticket until you arrive

Follow the signs and use the correct gates when entering and exiting the station.

For the Express Train, AREX advises passengers to arrive at the boarding area at least 3 minutes before departure.

Tips for Singaporeans to Use AREX

These tips can make your journey much easier:

1. Choose the right AREX service. The Express Train runs directly between Incheon Airport and Seoul Station, while the All-Stop Train stops at more stations along the way. Pick the one that suits your hotel location and travel plans.
2. Check which airport terminal you are using. Incheon Airport has Terminal 1 and Terminal 2, so check your flight details before heading to the station. The travel time can also vary depending on your terminal.
3. Know where you can board the Express Train. The Express Train connects Incheon Airport Terminal 1, Terminal 2 and Seoul Station. If you are staying around Hongdae or Gongdeok, use the All-Stop Train instead.
4. Book the right ticket. AREX Express and All-Stop services use different ticketing arrangements, so check your ticket carefully before travelling.
5. Consider your hotel location before choosing your train. Seoul Station may not be the most convenient stop for your accommodation. If you are staying near Hongdae, Gongdeok or another AREX station, the All-Stop Train may save you from making an extra transfer.
6. Leave room for luggage. Seoul's train stations can get busy, especially during morning and evening peak hours. Give yourself extra time to move around with large suitcases.
7. Plan around your flight time. When travelling from Seoul to Incheon Airport, allow enough time for the train journey, airport check-in, security and immigration. For an international flight from Singapore, arriving at the airport early can make the journey much less stressful.
8. Check the latest timetable before leaving. Train frequency and operating times can vary by day, so check the latest AREX schedule before heading to the station, especially if you have an early morning or late-night flight.

Final Thoughts

For Singapore travellers flying into Seoul, AREX is a convenient way to travel between Incheon Airport and the city. The main thing is choosing the right service.

Take the Express Train if you are heading straight to Seoul Station and want a reserved seat and a faster journey. Choose the All-Stop Train if you are staying around Hongdae, Gongdeok or another station along the AREX route.

Before you travel, check the latest AREX timetable for your specific date, especially if you have an early-morning arrival, late-night flight or airport check-in to catch.
