It takes about the same time to travel by train from Koh Lanta to Bangkok via Surat Thani Railway Station, as it does to travel by bus. Travel by train is, however, a more comfortable option because you can book a sleeper berth as opposed to spending the night in an upright position on a bus which makes it difficult to sleep.

2nd Class AC carriage on a Thai trainBecause most trains from Surat Thani Railway Station travel overnight it is a good idea to book a sleeper berth. There three types of sleeper berths on train in Thailand, all of which are cheap compared to sleeper berths on trains in Europe or North America. The cheapest type of sleeper berths are in the 2nd Class fan carriages. These type of carriages tend to be old and they can get very hot because they are only cooled by small rotating roof fans. If you book the lower bunk on a 2nd Class fan carriage you can open the window which makes the journey a lot more bearable. There is no window on the top bunk. The next cheapest type of sleeper berths are in the 2nd Class AC carriages. These are the types of sleeper berth that most foreign visitors prefer to book because the carriages are fairly modern and cool even in the heat of summer, but still relatively cheap. Some trains in Thailand also have 1st Class carriages which are the most expensive and the best, although unfortunately there are normally only 24 of these berths on any train. 1st Class carriages have private air-conditioned compartments with two beds arranged bunk bed style, and a lockable door.
