Book excerpt: In the long and absorbing history of Britain's railways, the most challenging years were those of the two World Wars, when they were needed the most. Transportation of everything that was grown, made, or mined, as well as soldiers, sailors, airmen, and civilians largely fell to the nation's trains. Yet the indispensable role of railways in wartime has been largely overlooked. This book pays tribute to the way railway workers responded to the demand that they do more with less resources, called upon as they were to cope with an extraordinary change in the character and volume of passenger and goods traffic, to endure dangerously long hours, and to overcome the fear of moving in and through war zones. Small wayside stations could be transformed into a frenzy of activity by the arrival of a camp or supply depot on its doorstep, while disruption through bomb damage could turn the shift of the locomotive crew into an indefinite wait for relief. Featuring a gazetteer of the monuments and memorials created to honor fallen railway workers, this book pays tribute to their heroic responses to the demands of war.
