Practical tips
Wear light clothes, it gets hot, above all from March to June. Bring enough water and something to eat: vendors walk the platforms at stations, make the most of them. On a long trip, a book or music helps the hours go by.

The local experience
Third class is how Thai people travel every day: families, students, monks, traders. It is noisy, sometimes chaotic, always lively. Some travellers pick it for exactly that reason.
Picking your seat.
The car has 76 seats. On YesMyTrips, light blue seats are free and red ones are taken. On the official SRT site, green seats are free and pink or blue ones are taken.
A long trip? Think twice
Under two hours, third class is cheap and authentic. On a long trip like Bangkok - Chiang Mai, hard benches, heat and noise wear you out. An air-conditioned second class seat changes the comfort completely, and for a night on board a second class sleeper is clearly the better choice.
When and how to book it.
SRT opens sales 90 days before departure, at 08:30 Bangkok time.
Short trips
On trips under two hours (Bangkok - Ayutthaya for example), tickets are often bought on the day at the station counter.
Long trips
Book ahead to be sure of a seat. Sales open 90 days before departure, at 08:30 Bangkok time.
November to February
The best time: pleasant temperatures, windows open, a very enjoyable ride.
March to October
Intense heat until June, then showers from May to October that force the windows shut. Over several hours, weigh it against a second class seat.
Your date is not open yet? Book it ahead
Other ways to ride.
Second class seat
Padded seats by day, with air-conditioning or fans depending on the train. Assigned seat.
Classic second class sleeper
Open berths with curtains on the older trains. Cheaper, without the privacy of a cabin.
CNR second class sleeper
The same new carriages as an open car of 40 berths with curtains. Air-conditioned, bedding included.
Quick answers.
How much is a third class seat?
From 120 THB (US$ 3.55) to 419 THB (US$ 12.41) per seat, depending on distance and carriage. Bangkok - Chiang Mai: from 307 THB (US$ 9.09). Fares verified October 31, 2026, all fees included.
How far ahead can I book?
90 days before departure, from 08:30 Bangkok time. On shorter trips (under 60% of the line) the window can be shorter.
Is third class really uncomfortable?
It depends on the trip and the season. One or two hours in December with the windows open is pleasant. Ten hours in April at 38 °C is another story. A simple rule: third class is fine for up to three hours in cool weather, beyond that a second class seat is worth the difference.
Is there air-conditioning?
No. Third class has fans only, with windows that open. If you need air-conditioning, take an air-conditioned second class seat.
Can I board without a ticket?
On some ordinary trains, Thai passengers sometimes pay the conductor on board for short trips. As a foreign traveller, it is better to hold a ticket to avoid any misunderstanding.
Can I use the dining car?
Yes, on trains that have one. In practice, station vendors are better and cheaper: make the most of the stops, some last several minutes.
