Duffield Bank to Perrygrove. This book covers the different types and applications of 15" gauge railways from the Duffield Bank Railway of the 1870s (and its antecedents) to the modern pleasure park lines and sites. One of the unique features of the 15" gauge lines is the remarkable range of historic locomotives and rolling stock that have either survived in use or been recreated in replica; and whereas most books rely on historic black and white illustrations. This book shows that the 15" gauge story can be illustrated almost entirely from contemporary colour photographs.
