From about 382 THB per adult in total, on RP102 and RP133 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.
