As electricity became more widely used to power and light Britain's towns and cities a number of municipal boroughs built their own power stations. In the early years these were inevitably fed by coal, of which the UK had a plentiful supply. In the 1960s and early 1970s the government embarked on a programme of constructing new power stations. The majority of these were constructed with direct rail-connected on-site coal handling facilities and thus was born the Merry-Go-Round, or MGR, coal train. The book features a UK panorama of a wide variety of coal trains on the move, with previously unpublished images from across many years and locations.
