Lower or upper berth?
The lower berth is wider, has the window and turns into a bench by day. It always sells first. The upper berth is narrower but perfectly fine if the ladder does not bother you. With the curtain closed, privacy is decent but not total: bring earplugs and an eye mask, the corridor lights sometimes stay on at night.

Travelling as a family? Take a bay of four.
Berths come in groups of four, two lower and two upper facing each other. Book all four in one bay and you get an almost private space. For full privacy with young children, look at CNR first class and its connecting cabins instead.
Picking the right berth.
The car has 40 berths, half lower and half upper. On YesMyTrips every berth is labelled "upper" or "lower" and light blue means free. On the official SRT site, green means free. Odd numbers are usually upper berths and even numbers lower, with exceptions on some trains: trust the ladder icon, which only appears on upper berths.
Travelling as a woman alone?
CNR second class has carriages reserved for women, with the same berths. A reassuring option when travelling alone or with friends.
The ladies-only carriage →When and how to book it.
SRT opens sales 90 days before departure, at 08:30 Bangkok time.
High season (November to February, Songkran in April)
Book on opening day, 90 days out, from 08:30. Lower berths on the busiest trains can go within hours.
Low season (May to October)
Book within the first week after sales open, even on weekdays. Weekends stay busy all year.
Missed the opening?
Check again in the week before departure: SRT sometimes releases seats held for groups, and cancellations do happen. Not guaranteed, but worth a daily look.
If it is sold out
Move the date before you change class, and avoid Friday and Sunday nights. Otherwise classic second class often still has berths, on older carriages.

Quick answers.
How much is a CNR second class sleeper berth?
From 997 THB (US$ 29.68) for an upper berth to 1,247 THB (US$ 37.12), depending on distance and berth. Bangkok - Chiang Mai: upper 1,062 THB (US$ 31.62), lower 1,174 THB (US$ 34.95). Fares verified October 20, 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.
How is it different from CNR first class?
CNR second class is an open car: berths are separated by a curtain. First class is a private cabin for two with a lockable door and a washbasin. The CNR carriages are the same, only the layout changes. For most travellers, second class is very comfortable for much less.
Lower or upper berth: which one?
The lower berth is wider, has the window and turns into a bench by day. It costs a little more and always sells first. The upper berth is fine if you are not afraid of heights and do not need your luggage often.
Is it air-conditioned?
Yes, the cars are fully air-conditioned and the staff set the temperature centrally. It can feel cold: bring a sweater or a light jacket.
Can a family travel in second class?
Yes. Berths are grouped by four facing each other. Book all four in one group and you get an almost private space. With young children, first class with connecting cabins is more private.
Are there showers?
No, second class cars have no shower. There are toilets at the end of the car.
Are meals included?
No. The dining car is open to you, but value is average. Bring your own food or buy from vendors at stations, which is allowed (just skip the durian).
