Quick Summary
A subway transfer means changing from one line to another. Transfers are very common in Korea — one trip in Seoul often includes one to three transfers, so transferring is a core survival skill.
Key takeaways
- Transfers are usually free when you pay with T-money.
- Never leave the station gates during a transfer — follow the indoor transfer signs instead.
- Transfer stations show multiple line colours, transfer signs and direction arrows; some transfers happen on the same platform.
- Read transfer signs as line number + colour + direction, e.g. "Line 4 (Blue) → Sadang Direction".
- Walking 5–15 minutes with several escalators and long underground hallways is normal at large stations such as Seoul Station, Express Bus Terminal and Jongno 3-ga.
- Line 2 runs clockwise and counterclockwise — check the direction, not just the line.
- Watch out for express trains: they can skip your station.
- If you ride the wrong way, get off and move to the opposite platform.
- Screenshot your transfer route, exit number, final destination and station name before you travel.
- Check the last train time — the final transfer connection can end earlier than you expect.

Why It Matters
Without understanding transfers, you may ride the wrong train, accidentally leave the station, or waste a lot of time. Transfers are a core survival skill in Korea.
Transfers are everywhere
In Seoul especially, one trip often includes one to three transfers. Transfer stations usually have multiple line colors, "Transfer" signs, long underground hallways, escalators and stairs, and large maps.
Some transfers are surprisingly easy
In some stations you can transfer by simply crossing the platform — a same-platform transfer. This surprises many foreigners.
Others are surprisingly hard
Major transfer stations like Seoul Station, Gangnam Station and Jamsil Station can feel confusing and very large, sometimes requiring 5–15 minutes of walking.
Korean reality
Many foreigners expect transfers to work exactly like their home country. However, Seoul has one of the largest subway systems in the world. Long walks, multiple line changes, and complex stations are normal — don't worry if your first transfer feels confusing.
