The service was temporarily suspended from 15 March 1950 to 2 January 1954 due to war damage on the Southern line by bombs from Allied Forces during WWII as well as the insurgencies in southern Thailand and northern Malaya. The destruction of the Rama VI Bridge had compelled State Railway of Thailand (SRT) (replaced Royal State Railways (RSR) from 16 August 1939 to 1945) to use Thon Buri (Bangkok Noi) as the terminal for the "International Express" and the "Hat Yai Express" from 2 January 1944.
