A freight train which derailed and caught fire in South Wales consisted of 25 wagons each holding up to 100 tonnes of diesel or gas oil, investigators said.
The accident happened as the train passed through Llangennech, near Llanelli, at 11.15pm on Wednesday.
The Rail Accident Investigation Branch (RAIB) said the derailment and subsequent damage to the wagons “resulted in a significant spillage of fuel and a major fire”.
