In 1940 steam was the predominant form of motive power on the railways all over the world. In the ensuing 25 years the most complete metamorphosis came over the railways of the world--the most astonishing change in traction since steam locomotives replaced horses. In 1965 there remained no more than a few pockets in Europe where steam locomotives were in regular use. Only in India and southern Africa was there extensive use of steam. The transition period is of exceptional interest. In this book, O. S. Nock tells of the technical and sociological background to this absorbing period in the history of transport, which Clifford and Wendy Meadway have so vividly illustrated in colour.
Oswald Stevens "Ossie" Nock was a British railway signal engineer and senior manager at the Westinghouse company. He is best known for his prodigious output of publications on railway subjects, including over 100 books, as well as a large number of more technical works on locomotive performance.
