Overnight Train Bangkok to Chiang Mai: Times, Classes & Tips
How the Bangkok to Chiang Mai sleeper train works: reported times, classes, booking steps, and whether it beats flying or the bus. Verify on SRT.
On this page
Last updated November 2026: the overnight train Bangkok to Chiang Mai is a State Railway of Thailand sleeper service, with reported journey times of roughly 12 to 14 hours. Listings disagree on train numbers and departure times, so confirm every figure on the official State Railway of Thailand site before you book. Your trade-off is simple: you save a hotel night, but you give up speed and a guaranteed arrival time.

Overnight train Bangkok to Chiang Mai: quick answer

Yes, sleeper trains run this route, and most travelers book them to turn a night of travel into a night of sleep. Published snippets put the trip at about 12.5 to 13 hours 50 minutes. That is slower than a flight, which is why the train suits people with spare time. Our guide to whether Chiang Mai is worth visiting helps if you are still deciding on the trip itself. Every time below comes from search snippets, not from a timetable we have confirmed.
Bangkok to Chiang Mai sleeper train schedule

Three services appear in current listings, and they do not agree. One snippet describes Sleeper Train 109 as second class only, leaving Bangkok at 14:15 and reaching Chiang Mai at 04:05, a 13h50m trip. Another says No. 9 leaves Krung Thep Aphiwat at 6:40 p.m. and arrives at 7:15 a.m., about 12.5 hours. A third lists Express No. 51 with 2nd and 3rd class seats plus a 2nd class sleeper. We could not reconcile these, so treat the table as leads. SRT changes timetables, so check the date on its site.
| Train (per listings) | Reported departure | Reported arrival | Reported duration | Classes reported |
|---|---|---|---|---|
| Sleeper Train 109 | 14:15 Bangkok | 04:05 Chiang Mai | 13h50m | 2nd class sleeper only |
| No. 9 | 6:40 p.m. Krung Thep Aphiwat | 7:15 a.m. Chiang Mai | About 12.5 hours | Verify on SRT |
| Express No. 51 | Verify on SRT | Verify on SRT | Verify on SRT | 2nd and 3rd class seats (fans); 2nd class sleeper |

Sleeper vs seat: which class to book
Pick a 2nd class sleeper if you want to lie flat across a 12-hour-plus ride. Listings also mention 2nd and 3rd class seats with fans on Express No. 51. Seats cost less in most cases, but you would sit upright all night. Upper versus lower berths and air-conditioned versus fan cars are not confirmed here, so check SRT for each train. One snippet praises newer sleeper cars as cleaner and quieter, with air-conditioning and privacy. Treat that as a lead to verify, not a promise.
Sleeper Train 109 is listed as second class only, so Express No. 51 is the lead to verify for seats.

- Sleeper berth: best for light-packing travelers who want real rest.
- Fan seats: only if you can sleep sitting up.
- Newer carriages: ask SRT which train uses them.
How to book overnight train tickets

Start with the SRT website and its official booking channel for timetables, classes and fares. Third-party agents also sell these tickets, but their fees and ticket formats are not verified here. Bring your passport, since foreign travelers should expect ID checks. Confirm whether you get an e-ticket or must collect paper tickets. No booking window is confirmed, so book early for peak season, when sleepers can sell out. No fares are verified here either, so read the price on the official page.
Station and arrival logistics

Snippet 4 names Krung Thep Aphiwat Central Terminal as the Bangkok departure point for No. 9. Confirm the station for your train before you leave your hotel, and arrive with a buffer. Arrivals at 04:05 or 7:15 a.m. in Chiang Mai are very early for check-in. Ask your property about early check-in or luggage storage in advance. Our guide on Where to Stay in Chiang Mai: 6 Best Areas by Traveler covers areas to compare. Orient yourself with the Chiang Mai Old Town: Layout, Routes and Planning Guide layout before you land. Breakfast venues near the station are not verified here, so we name none.
Train vs flight vs bus: which should you choose?

Flying wins on time, and the train wins when you value a saved hotel night. The 12 to 14 hour figure is the only duration the snippets support. Costs and door-to-door times for flights, buses and vans are not verified here. We mark them "verify" rather than guess. Weigh them against your schedule and your tolerance for early arrivals.

| Mode | Total time | Cost | Pros | Cons |
|---|---|---|---|---|
| Sleeper train | About 12.5 to 13h50m (reported) | Verify on SRT | Saves a hotel night; lie-flat berth | Slow; delay risk; very early arrival |
| Flight | Verify | Verify | Fastest in the air | Airport transfers add time; verify |
| Bus or van | Verify | Verify | Verify | Verify |
What the night is really like

Bedding, noise and temperature are not confirmed in our sources, so we will not promise them. One snippet claims clean bedding, air-conditioning and privacy on newer cars. Ask SRT whether your train uses those. Bring a charger, a layer for cold air-conditioning, and snacks, since on-board food is unverified. Keep valuables on you while you sleep. Delay risk is real on any long rail journey, so do not book a tight onward connection for the arrival morning.
Who should skip the sleeper train
Skip it if you sleep lightly, if your schedule is tight, or if you need a guaranteed on-time arrival. Travelers with mobility limits should check berth access with SRT before booking. If any of those apply, compare a flight instead. Once you land, use our 10 Things to Do in Chiang Mai: Temples, Markets & Day Trips guide to plan the first day.

Arrivals at 04:05 or 7:15 a.m. leave little margin if the train runs late, which matters most for travelers on a tight schedule.
- Light sleepers: berths still carry train noise.
- Tight schedules: arrival time can slip.
- Mobility limits: confirm access with SRT.
