Hugh Llewelyn has travelled throughout Britain to gather this collection of his photographs of the diesel shunters. In addition to the main classes deployed by British Railways from the 1940s up to the present time, he also covers many of the rarer engines to be found working the docks and industrial centres. The shunters are shown in great detail and the images include not only the preserved examples, but also many of the neglected engines either in storage or abandoned. The result is a fabulous visual reference for rail enthusiasts with a wealth of detail for model makers.
