A devastating rail disaster in northeast Thailand has left at least 31 people dead after a construction crane collapsed onto a speeding passenger train, causing it to derail and burst into flames. The accident occurred as the train was travelling from Bangkok to Ubon Ratchathani, carrying nearly 200 passengers. More than sixty were injured, several critically, as fire engulfed damaged carriages. The crane was part of a Thai-Chinese high-speed rail project, part of an ambitious plan to connect China with south-east Asia. The company concerned was involved in the construction of a Bangkok building which collapsed in March during an earthquake. Witnesses described scenes of chaos, with carriages torn open and rescue workers scrambling to reach trapped passengers. Authorities have ordered a full investigation, while political leaders have vowed accountability. The tragedy has shocked the nation and renewed public scrutiny of large infrastructure projects and the human cost when safety is compromised.
