Wang Pho Viaduct

Wang Pho Viaduct is a historic wooden trestle railway viaduct on the Burma Railway (Death Railway) in Lum Sum, Sai Yok District, Kanchanaburi Province, Thailand. Located near Wang Pho Railway Station, it was built in 1942-1943 during World War II. The viaduct runs along a cliffside above the Khwae Noi River with wooden supports and steel rails. Still used by the Nam Tok branch line, it is a heritage site and photography point along the Death Railway route.

Visitors can expect an open-air historic railway viaduct built on wooden trestles along a limestone cliff above the Khwae Noi River. The structure consists of wooden supports carrying a single narrow-gauge track that is still active. Visitors can walk alongside the tracks when no train is passing, view the river valley and forested hills, watch the daily passenger train cross the viaduct, and explore the adjacent Wang Pho Railway Station area with small shops and food stalls.

Built in 1942-1943 as part of the Thailand-Burma Railway (Death Railway) constructed during World War II to connect Thailand and Myanmar. The viaduct is a wooden trestle structure built to carry the railway along the cliff above the Khwae Noi River and remains one of the preserved original viaduct sections of the line, which was constructed using Allied prisoner-of-war and Asian labour.

Serves as a preserved heritage site and memorial associated with the Death Railway, reflecting wartime railway engineering and local history. It is a point of remembrance and education for visitors learning about the railway's history and is part of the cultural tourism route along the Khwae Noi River in Kanchanaburi Province.
