Best Train Journeys in Thailand

It’s been over a century since Thailand’s first train line—a scant 50 miles linking Bangkok and the former royal capital of Ayuthaya—was completed. Tracks have since been extended to most parts of the country. While train travel has been largely surpassed by buses and air travel, scenic railway routes and sleeper trains remain one of the best ways to experience the beauty of Thailand.

Even the Thai government recognizes the renewed potential of railways. There’s ongoing talk of high-speed rail lines, and Bangkok’s modern Bang Sue Grand Station is reportedly Southeast Asia’s largest rail hub.

Currently, Thailand’s rolling stock may not be the most advanced, but trains operated by the State Railways of Thailand (SRT) are typically on time, comfortable, and charming in a nostalgic way.

If you’re not in a hurry, trains provide good legroom (especially in sleeper cars), delicious Thai food from dining cars or local vendors, stunning views, historic train stations, and quirky experiences, such as routes that pass through bustling fresh markets.

Here are the six best train journeys in Thailand.

1. Mahachai Line

Start – Thonburi; End – Samut Songkhram; Distance – 50 miles/80km

This short, popular commuter line starts near Bangkok and famously ends right in the middle of a wet market. Board the train at Thonburi’s Wongwian Yai station, where trains travel hourly to Samut Sakhon—known locally as Mahachai.

During the journey, passengers can observe houses, temples, and shops located an arm’s length away from the passing train. The landscape transforms into palm trees, rice fields, and marshes filled with lush plants and flowers.

Once you arrive in Samut Sakhon, you’ll walk through one of Thailand’s busiest fresh markets before reaching a harbor filled with fishing boats. A ferry ride across to Baan Laem connects you to another train heading to Samut Songkhram, where lively market stalls occupy the tracks and create a bustling atmosphere when trains arrive and depart.

2. Death Railway

Start – Thonburi; End – Nam Tok; Distance – 258 miles/415km

Constructed during World War II, the Death Railway serves as a poignant historical journey. Originally built under the harsh conditions faced by Allied POWs and forced laborers, this railway runs through rugged, scenic terrain, boasting intricately constructed bridges.

One key highlight is the bridge spanning the “River Kwai,” near Kanchanaburi, which stands as a significant historical landmark. While this line primarily utilizes third-class carriages with wooden benches and no air conditioning, it allows for a unique glimpse into history paired with beautiful scenery.

3. Sleeper Train to Chiang Mai

Start – Bangkok; End – Chiang Mai; Distance – 467 miles/751km

This classic route links Bangkok with the northern city of Chiang Mai, offering a memorable experience on one of Thailand’s sleeper trains. Departing in the afternoon, the journey transitions into night, allowing passengers to awake to stunning views of northern Thai countryside in the morning.

Travelers are treated to scenic sights as the train navigates through tunnels and lush forests. Note that more expensive tickets may offer an upgraded experience on newer train models.

4. Beach Train

Start – Bangkok; End – Hua Hin; Distance – 131 miles/212km

Winding around the Gulf of Thailand, this route provides glimpses of captivating scenery, including seasonal coconut plantations and salt flats. Hua Hin, a historical beach destination, features Thailand’s most beautiful train station, built in 1926 with an iconic Victorian design.

5. Night Train to Laos

Start – Bangkok; End – Thanaleng; Distance – 402 miles/648km

Departing from Bangkok, this international route crosses the Mekong River into Laos. Travelers can experience the comfort of overnight sleeper trains while witnessing picturesque rural landscapes, including rice fields and quaint villages.

Upon reaching Nong Khai, passengers cross the Friendship Bridge to Laos, where the journey continues into the capital of Vientiane.

6. Eastern & Oriental Express

Start – Bangkok; End – Singapore; Distance – 1,100 miles/1,800km

For those seeking a luxurious experience, the Eastern & Oriental Express offers an all-inclusive journey that evokes the glamour of train travel from a bygone era. Passengers enjoy private cabins and gourmet dining on this three-night, four-day adventure, with opportunities to explore both Thailand and Malaysia along the way.

Conclusion

Experiencing train travel in Thailand delivers not only stunning landscapes and unique cultural encounters but also allows passengers to connect with the rich history of the country. Whether you choose the historical Death Railway or the sleeper train to Chiang Mai, every journey is a memorable chapter in your Thai adventure.
