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 Surat Thani to Udon Thani?

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

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

Take RP172 at 20:55, change in Bangkok and continue on EX75. The whole trip takes about 20h, including 1h 12m to change trains.

What is the cheapest train from Surat Thani to Udon Thani?

From about 460 THB per adult in total, on RP172 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.
