The Thai-Burma railway survived being bombed by the Allies in 1944-45 and successfully provided supplied to Japanese soldiers in Burma. However, it was decided by the Allied authorities at the end of the war that it would be too difficult to maintain the structure. So it was demolished in 947.
The Hellfire Pass was also demolished after the war, but was rediscovered in the 1980s and is now the site of Anzac Day ceremonies and the Hellfire Pass Memorial Museum. It is remembered as a symbol of the Japanese Atrocities and a memorial for the many Australian lives lost under Japanese control.
