This book is first and foremost the story of the enginemen and their steeds which brought the steam era to an end on the Southern. It is therefore primarily about locomotive performance but enlivened by stories about how that was achieved and also about the band of young men who followed the exploits of men and machines, day and night over those last two years. It includes a substantial contribution from an ex-Nine Elms fireman and many anecdotes about the enginemen. The book contains about eighty train running logs plus records of lineside observations, detailed descriptions of the work covered by the locomotives and crews from the various steam motive power depots, copies of the actual duty rosters posted at Nine Elms, together with a unique collection of about 150 black and white and color images taken in the 1965 to 1967 period covered by this book. It is the most comprehensive story of those last few years yet produced, and it is truly The Untold Story, a fine tribute to the enginemen who performed near miracles with their doomed and run-down fleet of locomotives, in the very different world of the mid–1960's railway, unequaled anywhere else in Britain.
