Bituminous Coal as a fuel rail of the history of World War II.
After Japan lost the war in the year 1945 the alliance was another historic railway line two year and has been using coal freight trains through the country from India through Burma Thailand in the Sangklaburi district and bring to the division include fuel station and Kin Sai Yok evidence today.
THREE TIER BRIDGE (1943-1948)
This bridge was made by British and Dutch POWs and forced Asian laborers under supervision by Japanese Army Bridge Engineers. It is about 70m long and was about 8m high. It was a Three tiered bridge, meaning that it had 3 levels of timber construction before it reach height of the earth embankments on either side of the river. The rock and earth embankments on South West end of bridge reach an unbelievable height of 20m and and is 800m long. This embankment would have taken over 3 months to make by hand, with POWs carrying rocks and soil from over 200m away as areas closer were used up. A bridge was made here due to the large creek.
The use of solid concrete footings proves the Japanese were concerned about the amount of water flowing down creek in wet season. Otherwise easier rock and concrete footings would have been used. Railways must be as flat as possible due to lack of friction between steel wheels and steel rails. So “Cut” and “Fill” technique is used. Large wooden beams were bolted the anchor bolts used to lock down the base beams for each trestle.
EARTH CRATERS MADE BY POWs (Prisoner of War)
On either side of this large embankment you will see what looks like a “lunar landscape” with many deep holes in the rocks. This unique landscape has been fade by the POWs digging the soil from between the rock outcrops and using it to construct the embankment you are now standing on. It was difficult and boring work over several months as each section of embankment had to be made.
There are 3 kilometers of hand made embankment just on this special “Memorial Walking Track” at Kinsaiyoku area. In the wet season the red clay soil became thick mud making each stretcher load heavier and more difficult for POWs to climb the side of embankment due to slippery mud*- This embankment would have been made during infamous “Speed Period” when POWs were forced to work 12-16 hours per day for 100 days straight without a break! No rest. They died like flies due to overwork and from diseases like malaria, dysentery and cholera.
