This is the sixth volume in the series of books researched and written by the late Harold Bowtell describing the temporary contractor’s railways of all gauges used in the construction of Britain’s water reservoirs. This one covers the whole of South Wales and in editing the original manuscript Geoffrey Hill has been careful to retain the late author’s style and format used in the previous volumes. Published by our friends in the Industrial Locomotive Society we are distributing it to retail and trade customers on their behalf.
