Travellers recognise the Bridge over the River Kwai from the Oscar‑winning film, but the true story is even more compelling.
The bridge stands just outside Kanchanaburi, roughly 130 km west of Bangkok.
The Death Railway’s Dark History
During World War II, Japanese forces occupied Thailand and started building a rail link to Burma to supply their troops. They brought over more than 250,000 Southeast Asian civilians to work on what became known as the Death Railway. These included Thai, Malay and Chinese labourers. Around 60,000 Allied prisoners of war also worked on the project.
The conditions were dire. Over 90,000 civilians and about 12,000 Allied soldiers died from malnutrition, disease and brutal treatment.
The Real Bridge vs Hollywood Fiction
Unlike the towering timber bridge depicted in the 1957 movie, the real Bridge over the River Kwai was a steel structure. British POWs stationed at Tha Markam built it in 1942–43. Materials came from Java, and it was the only steel bridge Japan built in Thailand.
Colonel Philip Toosey commanded the prisoners. He worked covertly to slow construction and did not collaborate with his captors, unlike the fictional Colonel Nicholson. The Japanese initially erected a temporary wooden bridge in February 1943. They followed this with the permanent steel bridge with eleven curved‑truss spans in June 1943. The spans, shipped from Java, are the ones you see today.
How the “River Kwai” Got Its Name
The “River Kwai” name resulted from a language mix‑up. The bridge actually crossed part of the Mae Klong River. British prisoners pronounced khwae (Thai for tributary) as “kwai,” which means buffalo.
When the film became popular, tourists poured in looking for “the bridge on the River Kwai.” So authorities renamed the stretch of river Kwae Yai in 1960. Allied bombers targeted both the wooden and steel bridges in 1944–45. Several spans were destroyed, and the surviving sections still show shrapnel damage.
Visiting the Bridge Today
Today the Bridge over the River Kwai is a major attraction. Market stalls line the approaches. Buskers whistle “Colonel Bogey’s March” from the movie and memorial plaques honour the dead.
Taking the Death Railway Train
You can ride part of the original railway, often called the Death Railway, on a local train from Thonburi Station in Bangkok. Two third‑class trains depart daily at 07:45 and 13:55. Foreign travellers pay a flat fare of 100 baht.
After crossing the bridge, the line hugs cliffs above the Khwae Noi River. It passes the Tham Krasae wooden trestle and finishes at Nam Tok station near Sai Yok Noi waterfall. The morning train allows a return in the same day. However, many visitors stay overnight in Kanchanaburi to explore museums and war cemeteries.
Helpful Tips if You Plan to Visit
What to See
Cross the original steel bridge, noting the curved arches and straight replacement spans. Visit the nearby JEATH War Museum and the Commonwealth war cemeteries. These sites help you learn about the men who suffered on the railway.
Commemorations
Every November, Kanchanaburi hosts a sound‑and‑light show. The show re‑creates the bombings of 1944–45.
A Place of Remembrance
This bridge is more than a film set. It’s a solemn reminder of resilience and sacrifice. A visit offers both a scenic train ride and an opportunity to reflect on one of the Second World War’s most tragic episodes.
