Quick Answer
Trains in Thailand
Overnight sleepers, scenic rail journeys, and a piece of Southeast Asian travel history.
Thailand's rail network, operated by the State Railway of Thailand (SRT), is less glamorous than Japan's bullet trains but has a charm all its own. The overnight sleeper between Bangkok and Chiang Mai — rattling through rice fields and forest as the sun sets, then waking in the mist-covered mountains — is one of Southeast Asia's classic travel experiences. Trains are also practical: cheaper than flying for most routes, and you save a night's accommodation on overnight journeys.
Main Rail Routes
Northern Line (Bangkok Hua Lamphong to Chiang Mai): 13–14 hours, departures morning and evening. Sleeper berths available on overnight services. Southern Line (Bangkok to Hat Yai, with connections to Penang/KL in Malaysia): 14–18 hours south. Regular services plus overnight trains. Northeastern Line (Bangkok to Ubon Ratchathani, Nong Khai): Services to the Isan region and connections to Laos via the Thai-Lao Friendship Bridge. Eastern Line (Bangkok to Pattaya, Aranyaprathet): Limited service. Bangkok metro: Bangkok has the MRT (subway) and BTS (Skytrain) which are separate from the SRT network.
Train Classes and Costs
3rd Class (fan seats): Cheapest, basic wooden seats. Bangkok–Chiang Mai: 271 THB. 2nd Class seat (A/C): 500–700 THB. 2nd Class sleeper (A/C, upper/lower berth): 700–1,100 THB. 1st Class sleeper (private cabin, A/C): 1,200–1,800 THB. The overnight sleeper is the sweet spot for most travelers — comfortable, atmospheric, and cost-effective. Lower berths are wider and easier to access; upper berths are cheaper but higher. Book 1st class if you want privacy; 2nd class for the social experience.
Booking Tickets
Book online at thairailwayticket.com or 12go.asia (adds small booking fee). Walk-up tickets available at any SRT station. Advance booking opens 60 days before departure. Popular routes (Bangkok–Chiang Mai, Bangkok–Surat Thani) sell out for sleeper berths 2–4 weeks in advance on weekends and holidays. Hua Lamphong is Bangkok's main train station, accessible by MRT. Krung Thep Aphiwat (Bang Sue Grand Station) opened in 2021 and now handles most long-distance services.
