Is SRT Gone? How to Book Trains From Suseo Station in 2026

Last checked: November 2, 2026

SRT trains still leave from Suseo Station. Since September 1, 2026, Korail has run them along with every other high-speed train in Korea, and they now go by the name KTX-Sancheon. If you’re staying in Gangnam, Suseo is still a good place to start, and Klook is where I’d book first.

I read Korail’s own press releases on the merger, SR’s notice on the old app and Seoul City’s page on Suseo Station. For visitors, the open questions are mostly about cards and passes, and I’ve marked each one.

What changed on September 1

Korail’s August 2026 press release says the two high-speed operators run as one from September 1, and that SRT takes the name KTX-Sancheon.

Korail+, the merged app that replaced Korail Talk on August 3, searches and books Seoul and Suseo departures together, according to Korail. Until then, Korail and SR, the company that ran SRT, each sold tickets in their own app. The release says nothing about travelers from abroad, which is why parts of this guide are marked as unconfirmed.

Korail also cut KTX fares by 10% on average to match the old SRT level. Seoul to Busan went from 59,800 won to 54,400 won for an adult in a standard seat.

Yongsan to Gwangju-Songjeong dropped from 46,800 won to 42,000 won. I couldn’t find an official fare or travel time for Suseo to Busan, so you’ll see the price only when you search.

Where trains from Suseo go now

Korail’s release says it’s putting 955-seat KTX trains on the Suseo routes and adding trains from Suseo that run via Seodaejeon and Gupo stations. That doesn’t promise an easy booking. Search your own date with Suseo as the departure station before you settle on a plan, and book a Suseo train as early as you would a Seoul Station one.

Korail’s merger release gives no simple list of Suseo destinations, so search city by city with Suseo as your departure station.

How to book a Suseo train from abroad

For a Suseo train booked from abroad, I’d start with Klook. In early November, its Seoul to Busan page listed Suseo departures such as KTX 301, and it’s the only one of the three below where I could see one. I’ve seen the listing, not bought through it, so before you pay, check that your ticket shows Suseo, your date and your train number.

• Klook: it lists Suseo and Seoul departures separately on its Seoul to Busan page.
• Korail’s foreign-language site: since April 2025 you only need an email and a password to buy, according to Korail.
• Korail+ app: the merged app, which shows both stations at once.

Try them in this order. First, search Klook with Suseo as your departure station. If your date shows no Suseo train, try Korail’s foreign-language site, though whether it lets you choose Suseo is unconfirmed. If neither shows one, check the same trip from Seoul Station, which Klook also sells. Whether the Korail+ app accepts cards issued abroad is also unconfirmed, so keep it as a backup.

What about the SRT app and SR accounts?

In August, Korail and SR said the old SRT app would keep non-member booking for a period after the merger. Whether it still works in November is unconfirmed, so book through Klook or Korail instead.

If you made an SR account on an earlier trip, Korail says you have to convert it yourself on a page linked from its homepage. If you only ever had a Korail account, it carries over on its own. Members earn mileage worth 5% of what they pay, Korail says, including on trains to and from Suseo.

Korail also says you can switch to a train within seven days either side of your travel date without a change fee, up to 30 minutes before departure. I couldn’t confirm that this applies to bookings on the foreign-language site, so read the change rules on whichever site you use.

Can you use a KORAIL PASS from Suseo?

Before the merger, Korail’s pass page said the KORAIL PASS doesn’t include SRT. That page no longer loads, and I found no rule from Korail since September 1 on whether the pass now covers trains from Suseo.

Suseo or Seoul Station?

Pick whichever station is closer to your hotel, since Klook sells trains from both. Suseo is in Gangnam District, and Seoul City says it’s served by subway Line 3 and the Suin-Bundang Line. GTX-A also stops at Suseo, but at a separate station, so follow the signs when you change.

Seoul Station is on Lines 1 and 4, and the airport express train stops there. That makes it the easy choice from Myeongdong, which is on Line 4, or from Hongdae, which is on the airport railroad’s all-stop line. On arrival day it’s simpler still: the airport express train runs nonstop from Incheon to Seoul Station, so you can head for your train without changing lines.

Whichever station you pick, tickets go on sale two months ahead, at 7 a.m. Korea time on the same date. A December 31 train, for example, goes on sale at 7 a.m. on October 31, so you can work out your own sale day from your travel date.

If that date doesn’t exist two months earlier, as with a January 31 train, check Korail’s notice for the opening day. Holiday trains, such as those for Chuseok, go on sale in separate booking rounds that Korail announces ahead.

If you’re traveling on a Friday or a holiday weekend, I’d book on the day sales open for your date rather than wait.

FAQ

Is SRT cheaper than KTX now?

They’re the same system now. Korail lowered KTX fares by an average of 10% to match the old SRT level, so there’s no longer a separate SRT price to compare.

Can I still use the SRT app?

In August, Korail and SR said it would keep non-member booking for a period. It may no longer work, so use Klook or Korail’s own site instead.

Can I buy a ticket at Suseo on the day?

Yes, if seats are left. Korail’s May 2025 notice on foreign cards describes a priority counter for foreign travelers at Seoul Station. I couldn’t confirm the same setup at Suseo, which SR ran until September, so I’d book ahead.

Is Suseo the same station as GTX-A Suseo?

No. Seoul City says the GTX-A station at Suseo is separate from the high-speed rail station, so leave a few extra minutes if you’re changing.

If Korail publishes the KORAIL PASS rule for Suseo, I’ll update this guide the same week. Seen a different answer on your booking screen? Let me know through the Contact page.
