Trawsfynydd nuclear power station flasks were transported to Trawsfynydd on a section of the former Bala to Blaenau Ffestiniog railway that had been closed in January 1961. A single track was restored northwards with an entirely new line through the centre of Blaenau Ffestiniog that connected to the Conwy Valley branch. In 1963-4 a "Goliath" gantry crane was installed over sidings about east of the power station. Beginning on 20 April 1964, nuclear flasks could be transported by rail between destinations such as Sellafield in Cumbria. The last regular departure was on 8 August 1995. The last train to carry nuclear material from Trawsfynydd
Torness Nuclear Power Station AGR station. The construction, which was undertaken by a consortium known as National Nuclear Corporation ('NNC'), began in 1980. The reactors were supplied by NNC and the turbines by GEC. Torness was the last of the United Kingdom's second generation nuclear power plants to be commissioned (25 May 1988). The station consists of two advanced gas-cooled reactors (AGR) capable of producing a peak rating of 1364 MWe. Upon deregulation of the United Kingdom's electricity generation market it passed to the state-owned Scottish Nuclear, privatised as part of British Energy which was sold to the French company EDF in January 2009,
