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 Chiang Mai to Nakhon Ratchasima?
No. You change trains once, in Ayutthaya or Rangsit or Bangkok or Phachi, and book each train as a separate ticket.
What is the fastest way from Chiang Mai to Nakhon Ratchasima by train?
Take SP10 at 18:20, change in Ayutthaya and continue on SP21. The whole trip takes about 15h 41m, including 1h 33m to change trains.
What is the cheapest train from Chiang Mai to Nakhon Ratchasima?
From about 409 THB per adult in total, on SP14 and RP135 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.
