At about 23:15 hrs on 26 August 2020, train 6A11, the 21:52 hrs freight service from Robeston to Theale, conveying 25 tank wagons, each containing up to 75.5 tonnes of diesel or gas oil, derailed on the ‘Up District’ line near Llangennech, in Carmarthenshire. The derailment and the subsequent damage to the wagons resulted in a significant spillage of fuel and a major fire. The driver, who was unhurt, reported the accident to the signaller. Subsequent examination of the site revealed that a total of 10 wagons (positioned 3rd to 12th in the train) had derailed.
The fire was tackled by the fire service, who ordered the evacuation of local residents due to concerns for their safety. Local people have reported seeing a plume of flames and smoke, and the strong smell of fuel. Our investigation will seek to identify the causes of the derailment, and how these led to the fire. It will also consider any underlying management factors.
Our investigation is independent of any investigation by the railway industry, police or by the industry’s regulator, the Office of Rail and Road.
We will publish our findings, including any recommendations to improve safety, at the conclusion of our investigation. This report will be available on our website.
