Manod railway station goods transported were nuclear fuel rods carried in nuclear flasks to and from Calder Hall in Cumbria (later known as Sellafield). The line was also used during the late 1980s for freight traffic to a siding at serving the explosives factory in Penrhyndeudraeth. Passenger trains briefly returned to the line in 1989, passing through to a temporary platform at . These trains ran for one summer in an attempt to encourage tourism at the power station. Few people used the service to visit the power station, most riders travelled "for the ride", so the following year tourist trains drove to
Hartlepool Nuclear Power Station for a prototype fluidised bed combustion (FBC) coal station at Grimethorpe in Yorkshire. Because of this, the UK missed out on pioneering FBC technology, before it became internationally recognised as the best way of burning coal. Sited from Seaton Carew, and in the middle of the industrial complex of Teesside, the station was to be built closer to any major urban area than any nuclear power station site had been. To make this acceptable, the station's reactors were to be housed in prestressed concrete pressure vessels. The construction of the power station which was undertaken by Nuclear Design & Construction
