Network Rail has launched a legal claim against DB Cargo UK and Touax Rail seeking more than £5m in damages following a train derailment that caused a major fuel spill and threatened an environmental catastrophe at a protected wetland site. The incident, which occurred on 26 August 2020 near Llangennech in Carmarthenshire, resulted in 10 of 25 wagons leaving the tracks and releasing 446,000 litres of fuel into the surrounding area.
The derailment forced approximately 300 residents to evacuate as a fire broke out at the scene. Of the total fuel spilled, 116,000 litres ignited while 330,000 litres drained into wetlands designated as both a Site of Special Scientific Interest (SSSI) and a Special Area of Conservation. No injuries were reported in the incident.
In High Court documents filed earlier this month, Network Rail alleges that the derailment resulted from inadequate maintenance of the train's components. The body claims that Touax Rail failed to maintain the wagon
"with reasonable care"and is also pursuing DB Cargo UK for allegedly
"breach[ing] a contractual duty to ensure that reasonable care was taken"in the wagon's upkeep. Both companies have yet to file their legal defences.
What caused the derailment?
The Rail Accident Investigation Branch (RAIB) determined in January 2022 that the derailment was triggered when a set of wheels on one wagon locked, likely stemming from a brake defect. According to investigative reporting on the case, the brake defect arose from
"deficiencies in the design and maintenance of components."The RAIB's investigation identified
"inadequate maintenance practices"as a contributing factor. The locomotive was transporting the wagons from Milford Haven in Pembrokeshire to Theale near Reading when the incident occurred, and the train was travelling at approximately 38mph while carrying up to 75.5 tonnes of fuel.
What was the environmental impact?
The spill posed a severe threat to the protected wetland ecosystem. Bill Kelly, then-Network Rail Wales route director, stated when the line fully reopened in March 2021 that the recovery operation represented
"one of the biggest environmental recovery operations Network Rail has ever been involved with"and that the derailment could have caused a
"total environmental disaster."Firefighters took nearly two days to extinguish the blaze.
The scale of the cleanup was substantial: 30,000 tonnes of fuel-soaked soil required excavation. The railway line remained closed for six months following the incident and did not fully reopen for almost a year. However, according to Natural Resources Wales, the environmental regulator's pollution investigation concluded that there was insufficient evidence for a successful prosecution, and no charges were brought against any party. The authority stated it had investigated several companies but
"could not determine beyond reasonable doubt who was ultimately responsible for the derailment."
What happens next in the legal case?
A hearing in the civil negligence case is scheduled to take place, though no date has been announced. Network Rail's legal team has indicated it expects to recover
"more than £5m"from the defendants. Network Rail and DB Cargo have declined to comment on the proceedings, while Touax Rail was approached for a response.
