This book is a comprehensive history of all the 0-6-0 tender locomotives built by the Great Western Railway or by railways absorbed by the GWR from the very earliest broad gauge engines designed by Daniel Gooch to the Collett 2251 class of the 1930s some of which were still under construction at nationalisation. It includes the Joseph Armstrong ‘Standard Goods’ and the famous Dean Goods, many of which served overseas in the two world wars. The text of 40,000 words describes the design, construction and operation of eight GW and five ‘Absorbed’ broad gauge classes, and thirteen GW and thirteen ‘Absorbed’ standard gauge classes. The book has over 250 black and white and 30 colour photos, weight diagrams and drawings.
