The author's second volume about the Great Western's classic express locomotives covers their final six years in British Railways service. In 1960 the Castles, many now modernized with double chimneys and 4-row superheaters, were still in charge of most of the Western Region's expresses, but by the summer of 1963 their regular express work was limited to the London – Worcester route. Their declining numbers in the last couple of years covered special summer and relief trains, parcels and freight work, deputizing for failed or unavailable diesels and a flurry of excursions and railtours where their prowess could still be demonstrated. The author worked and lived alongside them in these years and the book includes much of his own personal experience on the footplate, on their trains and on shed. The book recaps briefly their first 25 years and covers their history, operation and performance in their final years and is copiously illustrated including over 100 color photographs.
