English Electric Class 20 locomotives once operated over virtually the entire rail network of Scotland. They were introduced to the Highlands in the late 1950s and are probably best remembered for working local freight traffic or working in pairs pulling coal trains in the Central belt. This book covers Class 20s from the BR era up to recent freight operations, and many locations across the country are featured.With a wealth of previously unpublished images, this book will delight Scottish rail enthusiasts both young and old.
