Are you currently traveling in Korea or planning a trip that involves moving between cities like Daegu, Gwangju, or Gangwon-do from Seoul or Busan? In such cases, the fastest and most convenient way to travel is by KTX or SRT high-speed trains. But don’t know how to book or ride them?
In this post, I’ll walk you through exactly how to use these two high-speed trains. I’ll also explain the exclusive benefit for foreigners, the Korea Rail Pass, which is available only on KTX. From how to reserve your seat to tips on getting the most out of the rail pass, everything will be covered in an easy-to-understand way for beginners.
How to Book Train Tickets
KTX: You can make a reservation via LetsKorail or through the Korail Talk app.
SRT: Book through the official SRT website or the SRT app.
Since the reservation systems are different, you’ll need to book each train separately on their respective platforms.
You can also book KTX only via Trip.com.
- All websites support English and are easy to use.
- Seat selection is available when booking.
- Popular routes sell out fast, so booking at least 10 days in advance is recommended.
Things to Know on the Day of Travel
- Arrive at the station at least 15 minutes before departure.
- Check the platform and train number in advance and head to the correct boarding gate.
- Be sure to sit in the assigned seat to avoid confusion.
- If you board the wrong train, ask a staff member. (I once got on an earlier train by mistake and had to get off midway and wait for the correct one.)
What is the Korea Rail Pass?
The Korea Rail Pass is a special unlimited-use train pass that can only be purchased by foreign tourists.
- It covers unlimited rides on most trains including KTX (AREX express and SRT not included).
- You can choose between 1, 3, 5, or 7-day passes.
- Just a couple of round trips on KTX already make the pass worth it.
Top Tips for Using the Pass:
Tip | Explanation |
---|---|
Plan long-distance routes | Focus on long routes like Seoul-Busan to maximize value |
Pack your travel into the pass days | Schedule regional trips within your pass validity |
Reservations still required | A pass alone doesn’t guarantee a seat — reserve in advance |
Use mobile tickets | Just show your phone, no need to print |
Summary: If you plan to ride KTX more than twice, the Korea Rail Pass is a no-brainer!
How to Buy the Korea Rail Pass
- Available for purchase on the KORAIL website or via Trip.com.
- After payment, you’ll receive a voucher via email which can be used for reservations and boarding.
- Passport information is required at the time of purchase!
KTX vs SRT – Frequently Asked Questions
Q1. What’s the difference between KTX and SRT?
A: KTX is operated by KORAIL and departs from major stations like Seoul Station and Yongsan Station. SRT is operated by a different company (SR) and departs from stations like Suseo and Busan. Both are fast and comfortable, but they have different operators, departure stations, and booking platforms.
Q2. Which is better for foreign tourists, KTX or SRT?
A: KTX is more favorable for international travelers because only KTX allows the use of the Korea Rail Pass. If your hotel is in Myeongdong or Hongdae, Seoul Station is convenient. If you're near Gangnam or Jamsil, Suseo Station is better.
Q3. Can I use the Korea Rail Pass on SRT?
A: No, the Korea Rail Pass is only valid on KTX, ITX, and Mugunghwa trains under KORAIL. SRT is a different company.
Q4. Is SRT cheaper than KTX?
A: Sometimes, SRT can be slightly cheaper. Early bookings (up to 30 days before departure) and off-peak hours can offer discounts up to 30%. Generally, the price difference is about 5–10%.
Q5. Can I mix KTX and SRT in my trip?
A: Yes, but you’ll need to book them separately.
Q6. Is there a direct train to Incheon Airport via KTX or SRT?
A: No direct train is available, but KTX connects to Seoul Station, where you can easily transfer to the Airport Railroad (AREX). In this regard, KTX offers better airport access.
High-speed trains in Korea are the best way to save precious travel time.
Even if it’s your first time, there’s nothing to worry about when it comes to booking and boarding.
Especially if you make good use of the Korea Rail Pass, you’ll be able to explore more cities without breaking the bank.
