As well as the Broad Gauge engines, the strange looking  Covertibles' of William Dean, a number of experimental  one-off' designs, the numerous Wolverhampton 0-4-2Ts of the  517' class and the Swindon built  2-4-0  Metro Tanks' are described with - where known - their allocation and operation. The book includes twenty weight diagrams and nearly 300 photographs, over 50 in colour. The four-coupled tank engines absorbed by the Great Western from other companies at or before 1923 will be featured in a separate volume to follow.","brand":"World of Books ","offers":[{"title":"Default Title","offer_id":53508690018577,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9781399022569.jpg?v=1778151849","url":"https:\/\/www.worldofbooks.com\/products\/books-four-coupled-tank-locomotive-classes-built-by-the-great-western-railway-by-david-maidment","provider":"World of Books ","version":"1.0","type":"link"}
