1. KTX & SRT — High-Speed Rail
The fastest and most popular way to travel between Korean cities. KTX and SRT reach speeds of up to 300 km/h. Unlike flights, you depart from the city center and skip airport procedures entirely.
Which Station Should You Use?
You don't have to go all the way to Seoul Station. Choose the station closest to your accommodation.
KTX stations:
- Seoul Station / Yongsan Station — Central Seoul
- Cheongnyangni Station — East coast destinations (Gangneung, etc.)
- Haengsin Station (Goyang-si) — Northern Gyeonggi area
- Gwangmyeong Station — Southern Gyeonggi area
SRT stations (Gangnam & southern Gyeonggi):
- Suseo Station / Dongtan Station / Pyeongtaek Jije Station
Tip: If you're staying in Ilsan, Goyang, or northern Gyeonggi — use Haengsin Station. You'll save 40+ minutes compared to going to Seoul Station first.
How to Book Tickets
Option 1 — Global travel apps (easiest for foreigners): Use Trip.com or Klook. Book in your own language and pay with your foreign card. Note: small service fee applies, and allocated seats sell out fast.
Option 2 — Station ticket counter (most reliable): Visit the ticket window at any train station a few days in advance. Staff can often find remaining seats that appear sold out on apps. Bring your passport.
Option 3 — KR Pass (best for multiple trips): If you plan to ride KTX multiple times within a short period, the KR Pass (foreigner-only unlimited rail pass) is a great deal. Note: KR Pass is not valid on SRT.
Critical Rules You Must Know
No ticket gates — it's a trust system: Unlike the subway, KTX and SRT stations have no QR gates or turnstiles. When it's time to board, check the departure board for your track number and walk straight to your seat. After departure, a conductor will verify tickets with a handheld device.
They will NOT wait — not even 1 minute: Korean trains depart with extreme punctuality. If your ticket says 14:00, the doors close at 13:59 and the train moves at exactly 14:00:00. Be on the platform at least 10 minutes before departure.
Avoid Korean National Holidays: Seollal (Lunar New Year, usually Jan–Feb) and Chuseok (usually Sep–Oct) are the two biggest holidays in Korea. Tens of millions of Koreans travel home simultaneously, and tickets sell out months in advance. During these periods, it is virtually impossible for foreign tourists to get a seat on KTX or SRT. If your trip overlaps with these dates, consider domestic flights or staying in one city.
2. GTX — Seoul Metropolitan Express Rail
The newest addition to Seoul's transit system — a subway that moves like a bullet train. GTX runs 40–50 meters underground at up to 180 km/h, dramatically cutting travel time from suburbs to the city center.
GTX-A Route (currently available)
North → Seoul: Unjeong Jungang → KINTEX → Daegok → Yeonsinnae → Seoul Station
Gangnam → South Gyeonggi: Suseo (SRT transfer) → Seongnam → Guseong → Dongtan
2026 Note: Samsung Station (COEX area) is still under construction and trains pass through without stopping. To reach Gangnam, transfer to the regular subway at Suseo or Seoul Station.
How to Ride GTX
No advance booking needed. Just tap your T-money card or WOWPASS at the gate — exactly like the regular subway. Transfer discounts to buses and metro lines apply as usual.
- First train: ~5:30 AM
- Last train: ~12:30–1:00 AM
- Train interval: every 15–20 minutes (much less frequent than the subway)
Platforms are very deep underground: GTX platforms are located 40–50 meters underground (equivalent to a 15-story building). From the station entrance to the platform, escalators take 5–10 minutes. If your phone says "train arriving in 3 minutes" when you're at the entrance, you will miss it. Always arrive at the station entrance at least 10–15 minutes before your train.
3. ITX & Mugunghwa-ho — Conventional Intercity Trains
Slower, cheaper, and more scenic than KTX. These trains stop at smaller towns KTX doesn't reach, and offer beautiful countryside views along the way.
ITX-Cheongchun — Korea's only double-decker train
Route: Seoul (Yongsan / Cheongnyangni) → Gapyeong (Nami Island) → Chuncheon. This is the recommended train for visiting Nami Island (Gapyeong) and Chuncheon. Book a 2nd floor seat for the best views.
ITX-Saemaeul / ITX-Maeum — Best value intercity
Mid-range between KTX and Mugunghwa-ho. Comfortable, wide seats at lower prices than KTX. Great when KTX is fully booked or doesn't stop at your destination.
Mugunghwa-ho — The retro budget train
Stops at every small town along the route. Very affordable fares. Best for slow travel and watching Korea's countryside pass by.
ITX-Cheongchun Has Ticket Gates: It shares platforms with the regular metro, so you must scan the QR code on your ticket at the gate before boarding. Do NOT tap your T-money card — that counts as illegal boarding and carries a heavy fine.
If you have a KR Pass, it's valid on ITX-Saemaeul, ITX-Maeum, and Mugunghwa-ho. Discounts also apply to tourist trains.
4. Tourist Trains — Ride the Scenery
These trains are the destination, not just the transport. Oversized panoramic windows, seats facing the mountains or ocean, and one-of-a-kind landscapes.
| Train | Route / Theme |
|---|---|
| V-Train (협곡열차) | Baekdudaegan cliffs and valleys |
| S-Train | Southern coast ocean views |
| Donghae Santa Train | East Sea coastline |
These trains run only 1–2 times per day and are extremely popular. Walk-up tickets on the day of travel are almost always sold out. Book in advance at any Korail station ticket counter or the official Korail website.
