Few steam locomotives so thoroughly embodied the spirit and character of their owner -- or were so widely respected. In the capable hands of NKP crews, Berkshires carded the weight of the railway's post-Depression solvency squarely on their shoulders. Published to commemorate the 40th anniversary of the Berks' retirement, this volume documents the fascinating history of these locomotives, from the dawn of the Super-power era through dieselization and today's museum-line survivors. A huge collection of action photographs and evocative paintings illustrate the Berkshires class by class, and complement rosters, diagrams and engineering records.
