In the late 1990s, English, Welsh & Scottish Railway (EWS) ordered a large fleet of 250 Class 66 locomotives to replace a variety of freight locomotive types that had been in service with British Rail for many years. However, EWS also required something with a bit more performance, as well as electric train supply, for hauling charter and mail trains, which were still quite common at that time. A partnership with Royal Mail resulted in the Class 67s moving post around the country. When Royal Mail ended that arrangement in 2004, the Class 67s were pushed into other areas of work, including light freight and occasional passenger services, as well as continuing with charters. Although the design of the Class 67s has not been to everyone's taste, they do at least add a bit of variety to the modern scene. During the 20 years that they have been in service, they have been very reliable with only occasional failures. Containing 220 images, this book illustrates all 30 locos in the class during their first two decades in service.
