At least 28 people have been killed after a construction crane fell on top of a moving train carriage at around 09:00 local time (02:00 GMT).
Official records show the train, which was carrying at least 195 people, had been travelling from Bangkok to a province in northeastern Thailand.
The crane had been working on a high-speed rail project linking Thailand and China.
The impact caused one train carriage to derail and another to catch fire.
The governor of the State Railway of Thailand has been ordered to “thoroughly and comprehensively” investigate the cause of the accident
