Nuclear flask trains
These trains have been running in North Wales since the mid 1960's using a variety of motive power. The working of them was reorganised in 1994. The Trawsfynydd branch was reopened after a period of closure to permit all the spent fuel on site to be removed to Sellafield. The working from Trawsfynydd was double headed by two 31s and at Llandudno junction it was combined with a single 31 on the train from Valley. The combined train was then treble headed to Sellafield. The working, under BR sectorisation, was booked for dedicated locos from the Trainload Coal fleet. However as these photos show there was considerable variety. More photos of the Trawsfynydd workings can be viewed on my Conwy Valley website.
