Trains to the South were suspended on Tuesday afternoon after heavy rains submerged railway tracks in Hua Hin in Prachuap Khiri Khan province.
Surapong Sutthipaen, acting Nakhon Si Thammarat railway station chief, said all the southern train services resumed at 4am. The Nakhon Si Thammrat-Bangkok service remained suspended on Wednesday due to a technical error related to the train schedules.
