Built by 5,000 prisoners of war and 30,000 locals, the 140-mile Sumatra railway was intended to move coal and troops across the island from Pakenbaroe on the north-east coast to meet up with an existing railway at Muaoro in the west of the island. The railway was completed on VJ Day, 15th August 1945. It was only ever used to transport POWs out of the area and then quickly became overgrown by the jungle.
