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 Udon Thani?

No. You change trains once, in Bangkok or Ayutthaya or Rangsit, and book each train as a separate ticket.

What is the fastest way from Chiang Mai to Udon Thani by train?

Take SP8 at 07:30, change in Bangkok and continue on SP25. The whole trip takes about 22h 09m, including 2h 45m to change trains.

What is the cheapest train from Chiang Mai to Udon Thani?

From about 762 THB per adult in total, on SP8 and RP133 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.
