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.
