Welsh Valleys Pontypridd to Port Talbot including the Maerdy Branch

The two Rhondda Valleys required a complex railway system to cope with their prolific coal output, which peaked at 9.1 million tons in 1914. The Avan Valley, with its additional industries, is also profusely illustrated. The complex network is explained with the aid of 34 detailed maps and some lengthy captions to the varied and historic photographs.
