This guide lists a total of 62 locations throughout Wales (including five on the borders in England) where heritage and tourist railways and related activities can be found. A total of 163 photographs support the text. Those five just in England are justified by their close proximity and their relevance to the Welsh railway scene. Of the total locations, the author has identified 57 specific routes of which 28 are operated as heritage/tourist railways, including projects and societies, and 29 as regular rail service routes operated in Wales. Finally, there are five museums including two which are dedicated to the Great Western Railway, one being just over the border in England at Coleford in Gloucestershire and the other, also in England, at Swindon in Wiltshire.
