This book covers all aspects of the popular Class 68s, including the order, construction and delivery of the fleet, and technical details. It looks at their operations on Chiltern and TransPennine Express services and their appearances on secondary passenger duties in Scotland, East Anglia and the Cumbrian Coast. This richly illustrated book contains not only photographs of the class around the UK, but also detailed diagrams and maps, full histories of the lines and details of future plans for the class.
