Over the years many of the abc 'Combined Volumes' have been reprinted to the delight of enthusiasts old and new, but the Summer 1957 edition, published in April of that year, has never been reprinted since the year of its initial publication. It lists all the locomotives operating on British Railways in the summer of 1957 and includes the significant numbers of pre-Grouping and Big Four locomotives that were still in existence as well as the British Railways built Standard locomotives. Also included are the diesel and electric locomotives and multiple units which were entering into service in increasing numbers following the Modernisation Plan of 1955.
This combined reprint also includes the Autumn 1957 Locoshed Book, which has also never been reprinted. Together, these two volumes provide a detailed picture of Britain's railways before the mass withdrawal of steam operation.
