The small firms that merged were stone quarries that had produced road setts, pre-mixed concrete, paint paper and even cosmetics. The constituent quarries had their own railway systems, often with inclines as they were located in mountainous regions. A large number of locomotives of several gauges feature prominently in the history of the quarry firms, from the first locos that used limestone and granite as track ballast, to the powerful Diesel locomotives. Ian Peaty had collected new material to form a complete company history of the Hanson Aggregates Group. The book is illustrated by numerous maps and diagrams, as well as modern and archive photographs and watercolour paintings. It will appeal to those in the aggregate industry, railway enthusiasts, industrial historians and modellers.
