Third class is the cheapest seat on the State Railway of Thailand: a fan-cooled carriage with open windows, sold at the station counter on the day, with no reservation. On short daytime trips such as Bangkok to Ayutthaya or the line to Kanchanaburi it is a pleasant, very cheap ride; for long journeys it is tiring, and a sleeper or a faster train is the better choice.
Most third-class seats are on the slow trains Thais call ordinary or local trains, which stop at almost every station. Some faster rapid trains also carry a few third-class cars. This page explains what you actually sit in, where these trains leave from, how to buy the ticket and where the slow way is worth it.
Overnight travel has its own guide: see Thailand's night trains for sleeper classes and berths. Booking reserved seats in the SRT's online system is covered in our guide to booking Thai trains online.

What you sit in: third class compared with the alternatives
Class on a Thai train describes the carriage, not the train. One long train can have air-conditioned second-class cars at the front and fan-cooled third-class cars behind. Ordinary trains are often third class from end to end. When you ask for a ticket, the clerk needs both the train number and the class.
| Seat | What it is like | Where you find it by day |
|---|---|---|
| Third class | Benches facing each other, ceiling fans, windows that open | Ordinary and local trains, some rapid trains |
| Second class, fan | Reclining seats, windows that open | Some rapid trains |
| Second class, air-con | Reclining seats, sealed windows, reserved | Express trains and diesel railcars |
| BNEX commuter | Air-conditioned railcar, seats sold on the day | Krung Thep Aphiwat to Ayutthaya only |
Third class is plain but not rough. Seat61, the long-running rail guide, describes it as generally clean and not crowded outside commuter peaks. Expect dust and noise through the open windows. A backpack or a small case is easier to manage than a big suitcase, because you find your own space on board.
Which Bangkok station the slow trains use
Since January 2023 the long-distance expresses leave from Krung Thep Aphiwat Central Terminal, but many slow trains did not move. Hua Lamphong, the old central station, still handles ordinary and commuter trains, the trains to Pattaya and the weekend tourist train toward the River Kwai. About 13 trains a day still run the 7 km from Hua Lamphong to Bang Sue junction, opposite Krung Thep Aphiwat, for 2 baht.
Two lines start elsewhere. The daily trains on the Death Railway leave from Thonburi station on the west bank, a walk of about 750 meters from MRT Bang Khun Non. The Mahachai line, the first half of the route toward the famous railway market at Maeklong, starts at Wongwian Yai. For the big terminal, our guide to Krung Thep Aphiwat station explains the entrances and platforms.
Check the departure station on the ticket, not just the city. "Bangkok" can mean Hua Lamphong, Thonburi, Wongwian Yai or Krung Thep Aphiwat, and they are kilometers apart. Ask the clerk to confirm it if the ticket is in Thai only.
Buying a third-class ticket at the counter
On local trains you just turn up, buy a ticket at the ticket office and board. There is no seat number; you sit where there is space. Because tickets are not tied to seats, a local third-class train cannot sell out, though you may stand for a while at busy times. Pay in cash and keep small notes.
Say or show the destination, the train number from the departure board, and "third class" (in Thai, chan sam). Ticket clerks at the main stations are used to foreign visitors. Keep the ticket until you leave the destination station, because the conductor checks it on board.
Reserved seats are a different matter. The SRT's D-Ticket system sells seats on long-distance and special trains, including some third-class seats on excursion trains, but we could not confirm that ordinary-train third class can be booked online. Plan on buying it at the station.
Fares: cheap, but not free
Third class is the cheapest way to cover distance in Thailand. We do not print a fare table, because the SRT's own site could not be reached when we checked in October 2026 and the fare depends on distance and train type; the counter shows the price before you pay.
Two claims you may read online are wrong or outdated. Third class is never free for foreigners. And the idea that Thais ride third class free as a standing scheme could not be confirmed: the only free-ride measure we found was a one-off for three days in May 2019. On the Death Railway foreigners pay a fixed tourist fare rather than the Thai fare; our page on that ride gives the details. This is a common pattern, explained in our article on dual pricing in Thailand.
If you want air conditioning for little more, the new SRT Bangkok Connex (BNEX) service from Krung Thep Aphiwat to Ayutthaya has run since 1 August 2026, with fares from 30 baht.
Delays and timetables
Slow trains are slow for two reasons: they stop everywhere, and on single-track sections they wait in loops for faster trains to pass. Double-tracking on the main lines has made the expresses faster, but an ordinary train can still lose half an hour or more. A late-afternoon express coming from far up-country can be late by the time it reaches you, too.
Use the slow train for the outward leg of a day trip, when the time does not matter, and check the return times at the station when you arrive. If you have a flight or an evening booking, leave a large margin or take a minivan back.
Vendors, food and the alcohol ban
On almost all Thai trains, even third-class ones, vendors walk through selling fruit, snacks and soft drinks. There is no restaurant car on ordinary trains. Bring water, especially in the hot months, and something to eat on longer runs; our guide to coping with heat applies on a fan-cooled train in April.
Since 12 May 2026 the sale of alcohol is banned on trains and in stations. Seat61 reports that drinking on SRT trains and stations has been banned since 2014 as well, so leave the beer for later.
The routes where third class is worth it
The slow train earns its place on short, scenic or historic trips by day:
- Bangkok to Ayutthaya. The classic first ride, under two hours. Our Bangkok to Ayutthaya train guide compares the ordinary train with BNEX and the expresses.
- On to Lopburi. The same northern line continues to the monkey town; see our Lopburi day trip.
- The Death Railway to Nam Tok. Third class only, from Thonburi via Kanchanaburi and the bridge. Our guide to riding the Death Railway has the times. Note that the weekend tourist train ends at Nam Tok Sai Yok Noi, and the Sai Yok park sites there have been shut since 27 September 2026; check before you book it.
- Chiang Mai to Lampang. About two hours; local train 408 leaves Chiang Mai at 09:35, a good day trip with a faster train back. See our guide to Lampang.
- Bangkok to Phetchaburi. Ordinary trains run from Thonburi and Hua Lamphong; our Phetchaburi day trip covers the town.
- Nong Khai to Laos. The short shuttle over the Friendship Bridge to Khamsavath near Vientiane carries third-class seats; our page on Nong Khai and the Mekong explains the crossing.
One famous slow route is not useful right now. The trains from Hua Lamphong to Aranyaprathet still run, but every land crossing to Cambodia has been closed since June 2025, so the train no longer leads to Siem Reap; see our page on the Thailand–Cambodia border.
When to skip it
Skip third class for anything over about five or six hours, at night, or with heavy luggage. Bench seats get hard, the open windows bring in dust, and you arrive tired. For Bangkok to Chiang Mai or the south, a second-class sleeper is far better value for the comfort.
Frequently asked questions
Can you book third-class train tickets in Thailand online?
Not reliably. Third-class seats on ordinary and local trains are sold at the station on the day without a seat number. The SRT's D-Ticket system sells reserved seats, mainly on long-distance and special trains.
Is third class on Thai trains safe?
For daytime trips it is a normal way for Thais to travel. Keep your bag on your lap or in sight, do not lean out of open windows or doors, and hold on when the train moves off. Phones near an open window are easy to drop.
Do third-class trains in Thailand have air conditioning?
Usually not. Third-class cars normally have ceiling fans and open windows; air-conditioned third class exists only on a few long-distance routes. For air conditioning on a short trip, choose second class or the BNEX service to Ayutthaya.
Is third class free for tourists?
No. Foreigners always pay. Claims of free third-class travel refer to Thai nationals, and we found no evidence of a standing free scheme in 2026.
