Advance Booking Dates for Train Tickets in Thailand

Starting from 1st July 2024, you can buy train tickets 180 days in advance for all long distance Special Express, Express and Rapid trains. However, you must be travelling at least 60% of the entire route to book 180 days in advance. If it is between 25% and 59% of the entire route, then you can book 30 days in advance. Less than 25% of the route, you can only buy one day in advance. Please also note, for local and commuter trains, usually numbered 3xx or 4xx, you can only buy these tickets on the day at the station. You cannot buy these kind of tickets online.

You can buy tickets up to 180 days in advance for these trains if your journey is at least 60% of the entire route:

You may notice that the travel agency websites such as 12Go sell tickets far in advance. These are not confirmed ticket sales. However, it does have the advantage that the minute these tickets go on sale, their agents will be in the queue to buy the ticket for you. This is very useful for popular routes such as from Bangkok to Chiang Mai.
