Good to know
- Each train is a separate ticket. Book the first train, then the second train for the day it leaves.
- Leave at least 2–3 hours to change trains. Long-distance trains, especially from the south, often run late, and a missed connection is not refunded.
- Most long-distance trains in Bangkok use Krung Thep Aphiwat Central Terminal, so you usually change in the same building.
- Times and fares come from our timetable and can change. The booking page shows the live times, seats and fares.

FAQ
Is there a direct train from Nakhon Ratchasima to Udon Thani?
No. You change trains once, in Kaeng Khoi or Saraburi or Ayutthaya or Bangkok or Rangsit or Phachi, and book each train as a separate ticket.
What is the fastest way from Nakhon Ratchasima to Udon Thani by train?
Take SP22 at 18:47, change in Kaeng Khoi and continue on SP25. The whole trip takes about 10h 52m, including 1h 53m to change trains.
What is the cheapest train from Nakhon Ratchasima to Udon Thani?
From about 343 THB per adult in total, on RP140 and EX75 in the cheapest available class.
How much time should I leave to change trains?
At least one hour at the same station. Long-distance trains, especially from the south, are often late, so a wait of 2–3 hours is safer. If you change between Hua Lamphong and Krung Thep Aphiwat in Bangkok, allow extra time to cross the city.
