The Burma–Thailand Railway: what it was and how its dead are remembered

The short answer

The Burma–Thailand Railway was built for the Imperial Japanese Army during the Second World War. The Thailand–Burma Railway Centre in Kanchanaburi says it was built using Allied prisoners of war and impressed Asian labourers.[12] The Australian Government's Hellfire Pass Interpretive Centre commemorates both the prisoners and the rōmusha, the Asian labourers who were forced to build it with them.[2]

Tens of thousands of people died building it, in the Hellfire Pass centre's words.[2] The sources give different dates and figures for the line, and this article reports them as they are given rather than choosing one. The dead are remembered in Thailand at the war cemeteries at Kanchanaburi and Chungkai, which the Netherlands War Graves Foundation says the Commonwealth War Graves Commission (CWGC) manages.[11] They are also remembered at the Hellfire Pass Interpretive Centre, an Australian Government initiative.[4]

Why it was built

The Hellfire Pass centre's history page says the Imperial Japanese Army built the railway because moving men and material to Burma by sea was too dangerous.[1] The Thailand–Burma Railway Centre describes it as a strategic military supply line for moving troops and equipment to the Burma Front.[13]

When it was built, and how long it was

The sources disagree on when work began. The Thailand–Burma Railway Centre says construction began in June 1942, at the Burma end.[13] The Hellfire Pass centre's history page says that in June 1942 a small group of prisoners was used to mark the intended route, and that construction began in October 1942.[1] XTOUR does not resolve the difference.

Both put the finish in October 1943. The railway centre says the Thai and Burmese sections were joined near Konkoita that month, after sixteen months of construction.[13] The Hellfire Pass centre says the railway was finished in October 1943, in twelve months.[1] XTOUR's reading is that the two durations follow from the two start dates.

The railway centre gives the line as 415 kilometres, built from both ends at once, from Thanbyuzayat in Burma and from Nong Pladuk in Thailand.[13] XTOUR has not read a length from another source.

Who built it

The Hellfire Pass centre counts more than 60,000 Allied prisoners of war forced to work on the railway, from Australia, Great Britain, the Netherlands East Indies and the United States. It puts the rōmusha, from countries such as Malaya, Singapore, Burma and the Netherlands East Indies, at approximately 180,000 to 250,000.[3] The Thailand–Burma Railway Centre says most of the labourers came from Burma, Java and Malaya, and that some 240,000 seems the most reliable estimate.[13] The Hellfire Pass centre says many died from cholera and malaria, from hunger, or from brutal treatment.[3]

How many died

No source XTOUR read gives a single count that covers everyone, and each figure below is an estimate in its source's own words.

• The British Embassy in Bangkok, in 2014, said some 13,000 prisoners of war from the Commonwealth, Holland and the United States died during the construction and maintenance of the railway.[10]
• The same release put the civilians who died, from Malaya, the Dutch East Indies and those conscripted in Siam, at an estimated 80,000 to 100,000.[10]
• The Thailand–Burma Railway Centre says over 13,000 prisoners of war died between late 1942 and late 1945, and that around 100,000 seems the most reliable figure for the Asian labourers.[13]
• The Netherlands War Graves Foundation says nearly 3,000 Dutch prisoners of war died building the railway.[11]

The Hellfire Pass centre says only that tens of thousands died.[2] Each page should be read before its figure is quoted.

Hellfire Pass

Hellfire Pass is the Konyu cutting. According to the Australian War Memorial, work on it began on 25 April 1943 with 400 Australian prisoners, and from July a further 600 Australian and British prisoners were added; for six weeks the prisoners worked shifts of 12 to 18 hours around the clock until it was finished in mid August. The Memorial says the Konyu section cost the lives of at least 700 Allied prisoners, 69 of them beaten to death.[8] The Hellfire Pass centre explains the name: prisoners working through the night by torchlight, a scene one of them likened to Dante's Inferno.[2]

Australia's commemoration there is recent. The centre's history page says former prisoners and tourists rediscovered the pass in the 1980s, when the Australian Government began planning a memorial, and that the Hellfire Pass Interpretive Centre was officially opened on 24 April 1998, with Prime Minister John Howard attending. Annual Anzac Day services at the pass began the next day.[1]

Bringing the dead together

The British Embassy's 2014 release says the graves of those who died, except the Americans, whose remains were repatriated, were moved from camp burial grounds and isolated sites along the railway into three cemeteries: Chungkai and Kanchanaburi in Thailand, and Thanbyuzayat in Myanmar.[10] The Netherlands War Graves Foundation says the Dutch dead were reburied in the same three cemeteries.[11]

Chungkai is different from the other two. The Hellfire Pass centre calls Chungkai a significant prisoner-of-war camp and hospital site, now a site of remembrance.[1] An Australian War Memorial photograph caption from September 1945 records two wartime cemeteries there, one with 1,500 graves and one with 168, and says the Australians buried in them were reburied in Kanchanaburi War Cemetery towards the end of 1945. The same caption says Chungkai War Cemetery is on exactly the same site that was used for prisoners' burials between 1943 and 1945.[9] The guide to Kanchanaburi's wartime sites sets out who looks after each site.

The bridges at Tamarkan

The Hellfire Pass centre's history page includes an Australian War Memorial photograph caption recording that the Japanese built two bridges over the Mae Klong near the Tamarkan prisoner-of-war camp, with prisoner labour, and that they were heavily bombed in 1944 and 1945. It calls Tamarkan the site of the famous Bridge on the River Kwai.[1] XTOUR has not read an official account of how the film differs from the history, so it offers none.

Why XTOUR does not map the railway

A railway line is a route, not a place, so XTOUR does not map the railway itself: it treats the cemeteries, the bridge and the interpretive centre as places, and tells the railway's story in articles like this one. Part of the line still carries trains. The Thailand–Burma Railway Centre says the line was sold to the Thai Government in 1947, and that by 1957 the section from Nong Pladuk to Nam Tok had been re-opened and still operates.[13] The Hellfire Pass centre says travellers can still ride the remaining 130 kilometres of track, to Nam Tok, and refers visitors to the State Railway of Thailand for the schedule.[6] XTOUR states no train times.

Visiting Hellfire Pass now

When XTOUR read the centre's news page on 9 October 2026, it said the centre and its walking trail were temporarily closed from 27 September 2026 until further notice, because of heavy rain, flooding and the risk of landslides and rockfalls.[7] XTOUR does not say when it will reopen. The centre's FAQ lists its hours and annual closure days and says entry is free.[5]

What XTOUR does not know

XTOUR has not read a national archive or a Japanese or Thai official account of the railway. The death figures above are estimates published by a government, a war graves foundation and commemorative bodies, reported as given.
