Best option (fastest + simplest)

For most travelers, the simplest workflow is: KTX from Busan Station → Seoul Station. It’s easy to navigate, well-signposted in English, and connects cleanly to Seoul’s subway lines.

If you’re considering SRT

SRT can be a good option depending on where you’ll end up in Seoul. SRT typically goes to Suseo Station (southern Seoul), not Seoul Station. If your destination is Gangnam / southeast Seoul, SRT may reduce local transit time.

Which station should you use?

Arrival (central Seoul): Seoul Station is the main KTX arrival point and best for connections.
Arrival (south Seoul): Suseo Station is where SRT typically arrives.

Common confusion

“SRT” is not a different station in Busan—it’s a different operator/brand and it often implies a different arrival station in Seoul (Suseo). Always verify the station name on your ticket before you go.
