This is the tenth and final volume in this series of regional books examining the industrial railways of England, Scotland and Wales. Following on from previous titles in the series, the author draws from both his excellent personal collection of photographs and from other contributors. Presented in both in colour and black and white, and accompanied by detailed captions, they reflect the changing face of industry in Wales over the last six decades or so. The diversity of the locomotives and the railways that once served industry in Wales is a fascinating and neglected subject, and both standard and narrow gauge systems, most of which no longer survive today, are covered within the pages of this book. From the slate quarries of North Wales and the steel works in the north and south of the Principality to the collieries of the South Wales Valleys and in the Wrexham area, these operations and much more are reviewed in this fascinating pictorial overview of the industrial railways that once supported the rich industrial heritage of Wales. Primarily utilising previously unpublished photographs, Gordon Edgar offers a fascinating insight into the industrial railways and locomotives of this region, endeavouring to convey the raison d'etre of such railways, which are held in great affection by many.
