The 'merry-go-round' train was developed in the 1960s as a way to transport coal from the coalfield to a power station, pasing slowly but not stopping as the coal was emptied through automatically-operated bottom discharge doors. This view is of Didcot power station, its gigantic cooling towers and a Clas 45 locomotive No 163. Photograph by T E Williams.
