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 Nong Khai to Nakhon Ratchasima?

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

What is the fastest way from Nong Khai to Nakhon Ratchasima by train?

Take RP134 at 20:15, change in Saraburi and continue on SP21. The whole trip takes about 13h 46m, including 2h 04m to change trains.

What is the cheapest train from Nong Khai to Nakhon Ratchasima?

From about 350 THB per adult in total, on EX76 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.
