Ten trains leave Bangkok for Chumphon every day in 2026. The fastest covers the 485-kilometre southern line in 6 hours 20 minutes; the slowest takes nearly 8 hours. Fares start at 192 THB for a fan-cooled third-class seat and reach 1,424 THB for a private first-class sleeping berth. All long-distance departures now leave from Krung Thep Aphiwat Central Terminal, not the old Hua Lamphong station.
What follows is the full timetable, the actual cost of each class, where to board, and the practical details that determine whether the train makes sense for your trip.
Bangkok to Chumphon Train Timetable – 2026
Nine trains depart from Krung Thep Aphiwat. One additional service leaves from Thonburi station on the opposite side of the river. The schedule below reflects the State Railway of Thailand’s current timetable, verified against the SRT D-Ticket master schedule as of 2026.
| Train | Depart | Arrive | Duration | Type |
|---|---|---|---|---|
| 43 | 07:30 | 13:50 | 6h 20m | Special Express (DRC) |
| 171 | 15:10 | 22:17 | 7h 07m | Rapid |
| 37 | 16:10 | 23:16 | 7h 06m | Special Express |
| 45 | 16:10 | 23:16 | 7h 06m | Special Express |
| 31 | 16:50 | 23:55 | 7h 05m | Special Express |
| 169 | 17:30 | 01:25 | 7h 55m | Rapid |
| 83 | 18:50 | 02:18 | 7h 28m | Express |
| 85 | 19:50 | 03:43 | 7h 53m | Express |
| 167 | 20:30 | 04:20 | 7h 50m | Rapid |
| 39 | 22:50 | 05:22 | 6h 32m | Special Express (DRC) |
The one remaining service from Thonburi is train 255, an Ordinary train that departs at 07:20 and arrives in Chumphon at 16:40. It takes 9 hours 20 minutes and is the cheapest option, but it runs on the older single-track section of the southern line and is substantially more prone to delay than the services from Krung Thep Aphiwat.
Bangkok to Chumphon Train Duration
The scheduled duration ranges from 6 hours 20 minutes to 7 hours 55 minutes. That spread is not random. It reflects two variables: the type of rolling stock and the number of stops.
The two Special Express Diesel Railcar (DRC) services — trains 43 and 39 — are the fastest. These are air-conditioned, seats-only sprinter trains that make fewer stops. Train 43 is the only daytime service that completes the journey in under 7 hours. Train 39 is the only overnight service that does the same.
Everything else falls into the 7-to-8-hour range. Rapid and Express trains stop more frequently and often share the single-track sections of the southern line with freight and commuter services. The slowest scheduled service is train 169 at 7 hours 55 minutes, arriving in Chumphon at 01:25.
Delays are the Normal, not the Exception
Scheduled times on the southern line are not reliable predictions. The route has a well-documented punctuality problem. Research on the southern intercity railway has identified single-track infrastructure and mixed traffic as the primary structural constraints — capacity utilisation on some sections exceeds 95 per cent, well above the 60 per cent threshold at which timetables retain flexibility to absorb delays.
In practice, this means a train scheduled to arrive at 22:17 might arrive after midnight. Traveller reports consistently mention delays of one hour or more, with some describing arrivals two to three hours behind schedule. A 7-hour journey can become a 9-hour one without warning.
This matters most for onward connections. If you are catching a ferry to Koh Tao, the overnight trains are timed to connect with the morning catamarans from Chumphon. Train 85, for example, is scheduled to arrive at 03:43, leaving enough buffer for the 06:00 Lomprayah pier transfer. A two-hour delay would still allow the connection. A four-hour delay would not.
Bangkok to Chumphon Train Ticket Prices by Class
Fares depend on the train type and the class of seat or berth. The table below shows adult one-way fares from Krung Thep Aphiwat to Chumphon.
| Class | Rapid trains | Express trains | Special Express trains |
|---|---|---|---|
| Third class seat (fan) | 192 THB | 232 THB | 272 THB |
| Second class seat (fan) | 300 THB | 340 THB | 380 THB |
| Second class seat (AC) | — | — | 510 THB (DRC) |
| Second class sleeper (fan) | 400–450 THB | — | — |
| Second class sleeper (AC) | 580–650 THB | 590–690 THB | 660–770 THB |
| First class sleeper (AC) | — | 994–1,194 THB | 1,034–1,234 THB |
Train 31, which uses newer Chinese-built coaches, sits at the top of the fare range. First-class upper berths on train 31 cost 1,224 THB, lower berths 1,424 THB. Second-class air-conditioned berths on the same train are 820 THB for upper and 920 THB for lower.
Children aged 3 to 11 pay reduced fares: 197 THB less in first class, 95 THB less in second class, and 41 THB less in third class. Children under 3 travel free.
What Each Class Actually Gets You?
Third Class (fan)
Third class is a padded bench seat in a carriage with open windows and ceiling fans. There is no air conditioning. On a 7-hour journey through central and southern Thailand, this is tolerable in the cool season and uncomfortable in the hot season. The fare is the lowest available, starting at 192 THB on Rapid trains. Luggage allowance is 30 kg.
Second Class Seat (fan or AC)
Second class seating comes in two forms. Fan-cooled carriages have reclining seats and open windows, similar to third class but with more padding and slightly more space. Air-conditioned second class seats are available on the DRC sprinter trains (43 and 39) at 510 THB, a fare that includes a small prepacked meal and soft drinks. Luggage allowance is 40 kg.
Second Class Sleeper (AC)
This is the most popular option for overnight travel. The carriage is air-conditioned. Seats convert into berths at night: an upper berth and a lower berth on each side of the aisle. Bedding is provided. Upper berths are narrower and closer to the ceiling; lower berths are wider and have a window. Fares range from 580 THB to 920 THB depending on the train and berth position. Solo travellers are often assigned upper berths unless they specifically request lower. Women travelling alone can request a women-only cabin on some services.
First Class Sleeper (AC)
First class consists of private two-berth cabins. Each cabin has an upper and lower bed, air conditioning, and a washbasin. The cabins are lockable from the inside. This is the most comfortable way to travel overnight, but it is also the most expensive: 994 THB to 1,424 THB depending on train and berth. Luggage allowance is 60 kg.
On the DRC sprinter trains (43 and 39), there is no sleeper accommodation. These are seats-only services. Train 43 is a daytime departure, so this is not a limitation. Train 39 departs at 22:50 and arrives at 05:22 — an overnight journey in a reclining seat rather than a bed. It is the fastest overnight option, but it is not a sleeper train.
Where to Board for Bangkok to Chumphon Train?
All long-distance southern line trains now depart from Krung Thep Aphiwat Central Terminal in the Chatuchak district of northern Bangkok. The station replaced Hua Lamphong as the city’s main long-distance rail hub and is one of the largest railway stations in Southeast Asia, with 26 platforms across three levels.
Getting to the Station
The MRT Blue Line stops directly beneath the station. The station entrance is in the basement, near Gate 13. Fares from central Bangkok range from 15 to 42 THB depending on distance, and trains run every 5 to 7 minutes.
The SRT Red Line commuter service also connects to the station. Platforms 3 and 4 serve the Rangsit and Don Mueang Airport direction; platforms 9 and 10 serve Taling Chan. Fares are 15 to 40 THB.
Taxis and ride-hailing services drop off at Gates 3 and 4. If you are arriving by car or taxi, the driver should be instructed to use Gate 4 — this is the main entrance for long-distance rail passengers and puts you closest to the ticket office and departure area.
Finding Your Platform
Southern line departures leave from platforms 7 and 8. These are on the ground floor. The walk from Gate 4 to the southern platforms is manageable, but the station is large enough that you should allow time if you are carrying luggage.
Security works like an airport. Gates open 20 minutes before departure. If you miss that window, you will not be allowed through to the platform. Arrive at least 40 minutes before your train if you need to buy tickets, pass through security, and find your carriage without rushing.
Facilities at Gate 4
The main ticket office is at Gate 4, with more than 20 counters. The departure board is also here — a large digital display that functions like an airport flight screen. A food court serves Thai meals: pad Thai for 60–80 THB, fried rice for 50–70 THB. Vending machines are scattered around for snacks and drinks. LockBox luggage storage lockers are available near Gate 4, though exact rates are not published online; expect to pay roughly 50–100 THB for a small bag and 100–200 THB for a large backpack per day.
There are no confirmed shower facilities. If you are connecting from an overnight train to another long journey, you will be using the toilets to freshen up. Charging points are available in the waiting areas near platforms 1–2 and 7–8; bring your own cable.
Booking Tickets
Tickets can be purchased at any railway station in Thailand, through the SRT D-Ticket website, or via the SRT D-Ticket mobile app. The official booking platform is at dticket.railway.co.th. Registration requires email verification.
The advance booking window for Rapid, Express, and Special Express trains is 90 days. This was reduced from 180 days in April 2026 to improve seat management and reduce unused bookings. Trains can be booked from 8:30 a.m. on the first day of the 90-day window.
Sleeper berths — particularly second-class air-conditioned berths — sell out well in advance, especially during Thai public holidays, school breaks, and the high season from November to February. If you want a specific berth type on a specific date, book as early as the window allows.
Online booking through the SRT D-Ticket platform incurs a small fee. Third-party agents such as 12Go and YesMyTrips also sell tickets, often at a markup, but with English-language interfaces and customer support. Combination train-and-ferry tickets to Koh Tao and Koh Phangan are available from travel agents in Bangkok but are no longer sold at SRT ticket offices.
Arriving in Chumphon
Chumphon Railway Station sits on Krum Liang Road in the centre of town. The station is a short walk from the night market and the main accommodation area. Motorbike taxis are available at the station entrance for 30–50 THB if you have luggage.
The station has a 24-hour luggage storage room on the northern end of the platform, next to the shop. This is useful if you arrive on an early-morning train and want to explore before checking in, or if you are waiting for a ferry connection.
Connecting to Koh Tao
Ferries to Koh Tao depart from Thung Makham Noi pier, about 25 kilometres from the train station. Lomprayah operates a bus transfer from the station to the pier, timed to meet the catamaran departures. The first transfer leaves the station around 06:00 for the 07:00 catamaran; the crossing to Koh Tao takes approximately 1 hour 45 minutes. Boonsiri Ferry also operates from Chumphon, with three daily departures from the station area. Ferry tickets can be bought at the station on arrival, or in advance through Lomprayah and Boonsiri directly.
The overnight trains from Bangkok are scheduled to arrive in Chumphon between 02:18 and 05:22, which aligns with the morning ferry departures. However, the delay risk on the southern line means a tight connection is never guaranteed. If you are booking a ferry for the same morning, choose a train with a scheduled arrival at least two hours before the ferry departure. Train 85 (arrives 03:43) and train 167 (arrives 04:20) provide the largest buffers for the 06:00 pier transfer.
Should You Take the Train to Chumphon?
The train is not the fastest way to reach Chumphon. Buses cover the same route in roughly the same time or slightly less, and flights from Don Mueang to Chumphon Airport take about 70 minutes. The train’s advantage is that it offers a wider range of comfort and price points than any other mode, and the overnight sleeper lets you travel while you sleep.
For onward travel to Koh Tao, the train is the most practical option for anyone who does not want to fly. The timing of the overnight services connects directly with the morning ferries, and Chumphon station is the transfer point for the island boats. The 7-hour journey is long, but it saves a hotel night in Bangkok and puts you on the pier in time for the first crossing.
For travel within the mainland — if Chumphon is your destination rather than a transit point — the daytime Special Express train 43 is the most efficient choice. It leaves at 07:30 and arrives at 13:50, covering the distance in 6 hours 20 minutes with air-conditioned seating and a meal included. It is the fastest scheduled service and the one least likely to be affected by the cascading delays that build up on the southern line through the evening.
