This third volume in the series on the Great Western Castle class locomotives focuses on the eight that have been preserved and goes into depth on the reconstruction of three of them, the two Tyseley ones, 5043 and 7029 described by Bob Meanley and Didcot's 4079 recounted by David Maidment from the records of the Great Western Society, including the full story of 4079's prolonged stay in Western Australia, its return to the UK and subsequent restoration. The history of all eight is covered and copiously illustrated, including over 100 colour photographs, with many during the restoration work by Bob Meanley and in operation by David Maidment. The book includes records of their operation and performance since restoration when some of the most remarkable performances of these locomotives were achieved.
