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 Si Thammarat to Ubon Ratchathani?

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

What is the fastest way from Nakhon Si Thammarat to Ubon Ratchathani by train?

Take EX86 at 16:00, change in Bangkok and continue on RP135. The whole trip takes about 26h, including 1h to change trains.

What is the cheapest train from Nakhon Si Thammarat to Ubon Ratchathani?

From about 447 THB per adult in total, on RP174 and RP139 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.
