The bridge over the river Kwai
The bridge over the river Kwai is a part of the Burma Railway that is located in Kanchanaburi.
The ‘Burma Railway’ or ‘Death railway’ was a 415 kilometres railway between Bangkok (Thailand) and Rangoon (Burma) (now Yangon, Myanmar).
In 1942 Kanchanaburi was under Japanese control. Asian forced labourers and prisoners of war were forced to build the infamous Burma Railway. Almost half of the prisoners working on the project died from disease, maltreatment or accidents. The railway was built to support Japan’s forces in the Burma campaign of World War II.
Nowadays it is a crowded tourist attraction. You can walk over the bridge even while the train is passing. Of course the train doesn’t drive fast and there are places to stand while the train is passing.
You should be careful though, because there are electric cables within reach and there are some loose screws. You are in Thailand, so you should worry about your own safety. Nobody else will take responsibility.
It’s not dangerous if you watch over your children and don’t hold on to any electric cables. Enjoy the view and the walk over a obviously old railway which was used in WOII.
