Reprinted with new full colour card cover, this book tells how, when the famous Elan Valley reservoirs were built the railway helped to transform this beautiful part of Wales to the sight known and loved by so many holiday-makers and day trippers today. The story of how the dams were built and why is beautifully told here. There is a fascinating insight into the men who built the dams and the village that was constructed for the navvy community. For all those interested in this part of Mid-Wales, railways and Victorian social history, this book makes compelling reading. Presented in A5 format, it contains 240 pages, 170 photographs/plans/documents, etc. and a large fold-out map.
