The Victorian and Edwardian periods saw the development of the steam locomotive in Britain from a comparatively simple machine to a powerful main line express capable of speeds of a hundred miles an hour. The book starts with an introduction dealing with the main lines of development in the north of Britain and that is followed by a picture section with over a hundred photographs. Each illustration has an extended caption giving details of the engine and its history. The material is arranged geographically, with sections dealing with the north of England, Wales, Scotland, Ireland and a separate section on light railways. The photographs are all of the locomotives in their working days, many showing them in action on both passenger and goods trains. This splendid collection shows the rich diversity of Britain's railways and how different companies and their engineers produced engines of great individuality. This is a book that will be enjoyed by all lovers of the golden age of steam railways.
