At least 30 passengers, mostly foreign tourists, were injured when a train derailed in the mountains of northern Thailand - the second derailment on the same route in a month.
State Railway of Thailand governor Prapas Jongsanguan said the overnight train from Bangkok to Chiang Mai skidded off the tracks in Phrae province and seven of the 10 carriages flipped on to their sides.
Railway authorities believe the accident was caused by old tracks due for repair.
Mr Prapas said one passenger was seriously injured and the rest had minor injuries and were given free transport to their destinations.
Another Bangkok-bound train from Chiang Mai derailed early this month but no-one was injured.
The Bangkok-Chiang Mai train is popular among foreign tourists.
