The KTX (Korea Train Express) is the fastest and most efficient way to traverse South Korea. In recent years, the network is more connected than ever, with new high-speed lines reaching Incheon and Suwon, and the “Blue Dragon” cutting travel times significantly. Here’s everything you need to know about getting around by KTX train in Korea.
Choosing your train: Speed and routes
According to the latest data, Korea’s high-speed rail has three main tiers:
- KTX-Cheongryong (Blue Dragon): It is the fastest train in Korea, reaching speeds of 320 km/h and cutting the Seoul-to-Busan trip to just 2 hours and 11 minutes. These trains offer the most legroom and modern amenities.
- KTX-Ieum: The “green” electric train. Since 2025, it has expanded to the Donghae Line, making it easy to travel from Seoul to eastern coastal cities like Gangneung and down to Bujeon (Busan) in one shot.
- SRT (Super Rapid Train): Departing from Suseo Station in Southeast Seoul. It’s the best choice if you are staying in Gangnam, Jamsil, or the southern suburbs.
Booking tickets
Tickets can be booked up to 30 days in advance. Demand for Friday evenings and Sunday afternoons is extremely high.
The “Korail Talk” app
The app has seen several UI updates. While it supports English, Chinese, and Japanese, many travelers still report issues with foreign credit card authentication.
Payment Tip: Use a “3D Secure” enabled card. If the app fails, many travelers find that booking through the Korail Global Website on a desktop is more stable for international banks.

The KORAIL PASS
The KORAIL PASS remains the best value for travelers planning three or more long-distance trips.
| Pass type | Adult (26+) | Youth (13–25) |
| 3-day consecutive | ~KRW 165,000 | ~KRW 132,000 |

| 2-day select (Flexible) | ~KRW 131,000) | ~KRW 105,000 |
The KORAIL PASS allows you to pick any 2 or 4 days within a 10-day period. Pass holders can reserve up to 2 seats per day for free. After that, you must purchase a standing ticket. Find out more on the KORAIL official website.
Navigating the station: Boarding made easy
Korea still operates on an “open station” policy. There are no turnstiles or gates. Simply check the departure board, find your platform, and board.
Major stations like Seoul and Busan have improved digital signage in recent years. Look for your car number (e.g., car 5) marked on the platform floor to ensure you are standing in the right spot.
At Seoul Station, you can now connect to the GTX-A line, allowing for rapid travel to suburban areas like Dongtan or Paju in under 20 minutes.
Onboard amenities and rules
Charging: All KTX-Cheongryong and KTX-Ieum trains feature wireless charging pads and USB-C ports at every seat. Older KTX-1 trains have power outlets located between the windows.
Luggage: You are allowed one piece of large luggage (up to 20kg). If the end-of-car racks are full, you can use the overhead bins for cabin-sized bags.
Food: Eating is fully permitted. Most trains have vending machines, but there are no “dining cars.” It is best to buy a Dosirak (lunch box) at the station before boarding.
Quiet Cars: If you need to work or sleep, select “Quiet Car” during the booking process. Talking on the phone is prohibited in these sections.
Pro-tips
- Avoid the “Sinchon” confusion: Many tourists accidentally go to Sinchon Station (Subway Line 2) instead of Seoul Station. Make sure your taxi or GPS is set to “Seoul Station” (서울역).
- Standing tickets: If a train is “sold out,” go to the station’s automated kiosk. You can often still buy a “Standing/Non-reserved” ticket. Look for the small fold-down seats in the hallways between cars—first come, first served!
- Punctuality: The KTX is famous for being on time. Doors close exactly one minute before departure.
