Death Railway (ทางรถไฟสายมรณะ), the strategic railway tracks began from Nong Pla Duk Station in Amphoe Ban Pong, Ratchaburi, and ran via Kanchanaburi across the Khwae Yai River, westbound to the Three Pagodas Pass, to end at Thanbuyuzayat in Burma. Total length within Thai territory was 300 km. The railway took only one year to complete, from October 1942–October 1943. After the war, some lengths of track were demolished and some submerged under the lake of Khao Laem Dam.
