The steam locomotive is a machine that has inspired imagination, innovation and invention from the time of its origination and continues to evoke passion in enthusiasts today.Here Michael R. Bailey, expertly and in fascinating detail, describes the development of the steam locomotive during its pioneering first half-century until 1850 by exploring the surviving locomotives that may be seen in Britain, Europe, and North and South America. In addition to surviving relics, he also takes a look at operable replicas, which fill many gaps in international collections, to provide continuity in this evolutionary story.Exploring in depth each example\'s operational and preservation history, along with design characteristics, component materials and modifications made, no detail is left unmentioned. With unparalleled detail, incredibly stunning images and a list of museums housing all of the world\'s oldest locomotives, this truly is a volume that no student of railway history should be without. 50 Illustrations, color; 250 Illustrations, black and white
