First published in 2005, Hugh Longworth's monumental work chronicling each steam locomotive operated by British Railways between 1 January 1948 and the end of main line steam in August 1968 has become a standard work of reference. Since the book's first publication, the author has been updating and correcting the information enabling the publication of a completely revised second edition. The new book includes data and illustrations of many of the classes and as a new feature, line drawings of each locomotive class listed in the book.
Covering all the locomotives inherited in 1948 as well as those constructed post-Nationalisation, the book enables the reader to identify precisely the history of each individual locomotive. Information provided includes technical data, modifications, date of construction, names, date of withdrawal and much more, thus providing the reader with a single-volume reference to the many thousands of steam locomotives operated between 1948 and the end of main line steam.
