What this means
These instructions are about navigating Seoul Station indoors from subway to KTX. They do not calculate a KTX-to-AREX transfer or provide a timetable; the final check should always be the live Korail departure board.
How to use this for your Korea trip

- Keep your ticket open so you can check the train number, departure time, carriage, and seat while walking.
- Travelers with large luggage should use elevators where floors change and allow extra walking time.

Frequently asked questions
How long does it take to walk from the subway to KTX at Seoul Station?
The time depends on your subway platform, the indoor route, and your luggage. Arrive early enough to read signs, use an elevator, and check the departure board.
Which signs should I follow after getting off the subway?
Look for KTX or Korail signs. Subway exit signs may lead toward streets and city neighborhoods instead of the KTX departure hall.
Does a KTX ticket show the platform number?
A ticket normally shows the train number, departure time, carriage, and seat. Confirm the platform on the station display because it can be updated.
Can I use an elevator with a large suitcase?
Yes. Elevators are useful at level changes, especially with heavy luggage. Avoid blocking escalators when the station is crowded.
What should I do if I take the wrong route inside Seoul Station?
Return to the nearest sign, search for KTX or Korail, and ask the information desk if needed. Walking the wrong way inside the station does not require a new ticket.
Is this also a guide for reaching AREX?
No. This page covers the subway-to-KTX route. Use the separate KTX–AREX transfer guide when you need the airport railway.
