Brush Type 4 Class 47 locomotives have seen more than sixty years of service on Britain’s railways, celebrating their diamond jubilee on 25 September 2022.This book draws together previously unseen photographs by the author and others who have spent decades photographing, traveling behind and preserving these locomotives. Looking at the early years of the fleet of 512 locomotives as they settled into hauling passenger and freight, as well as the halcyon years of the 1980s and 1990s and more recent times, Martin Measures shares the importance of these locomotives to the railways and their many enthusiasts. Lavishly illustrated throughout, this fitting tribute to the Brush Type 4s commemorates their long and successful service.
