Despite the industrial ravages of the Eighties, the landscape of Doncaster in England’s unfeasibly flat north-east is still one of railway sidings, chimneys and canals. There is, however, a recent exclusion from the horizon. Colliery winding gear, so long a feature of the terrain, has vanished, although from the window of a Hull-bound train you’ll still see the odd slagheap sprawled out like an oversized, fast-asleep Labrador. Coal, which powered the industrial revolution and the engines of the British Empire, is no longer mined in Yorkshire. In 1984, there were 56 pits in the region but the 2015 closure of Hatfield and Kellingley collieries brought to an end an industry that had been active since Roman times.
