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.
