The Dungeness nuclear waste train, operated by Direct Rail Services (DRS), is a vital component of the UK’s nuclear fuel transport system. It runs weekly, moving spent nuclear fuel from the Dungeness B power station in Kent to Sellafield in Cumbria for reprocessing and storage. This operation is part of the ongoing decommissioning process at Dungeness B, which ceased electricity generation in 2018.
EDF Energy Nuclear Generation Ltd is removing all nuclear fuel from the station, a process that is expected to take around five years. The fuel will be transferred to Sellafield for storage until a final disposal decision is made.
The train is typically hauled by two Class 68 diesel-electric locomotives operating in a top-and-tail configuration, ensuring maximum reliability and efficiency. These locomotives, such as 68005 Defiant and 68018 Vigilant, are part of a fleet specifically designed for mixed-traffic duties, including freight and passenger services.
The train includes specialized FNA-D wagons, which carry robust nuclear waste flasks. These flasks are engineered to endure extreme conditions, including high-impact collisions, fires, and submersion, ensuring the safety of transported materials throughout their journey.
Class 68005 “Defiant” & 68018 “Vigiliant” are seen [25th November 2024] at Kent’s most southernly rails at Dungeness and then at Sunset outside the disused Lydd Town Station, at the beginning a 400 mile overnight trek to Sellafeild in cumbria, to deliver two wagons of High level radioactive waste from de-fueling Dungeness Power station B.

The completion of defueling at Dungeness B will conclude this route’s operations, though similar transports are expected to continue elsewhere as other power stations undergo decommissioning. The UK government and the Nuclear Decommissioning Authority (NDA) are also planning for long-term storage solutions, including a proposed geological disposal facility (GDF), to handle the growing volume of nuclear waste safely.
The Dungeness B Recommissioning Project aims to reduce the time it takes to make the site habitable again. The project includes plans to use parts of the power station to create a community space with housing, art spaces, and a library.
