Over the past thirty years or so, many changes have taken place on Britains railway system none more so than in the 1980s and 90s with the withdrawal of many classes of diesel locomotives, thus cutting down greatly on the number of locomotive-hauled passenger trains. However, although classes such as Deltics, Class 40s, 45s and 50s have long been withdrawn, many examples of these classes have been preserved, and over the last few years have been seen on the main lines in charge of special enthusiasts trains. Coupled with the withdrawals of many classes of freight locomotive and the disappearance of much infrastructure, the changes become very noticeable. Roger Siviters book sets out to show a great many of the now classic locomotives in their everyday work of yesteryear, but also some of the many specials they can be seen on today in this impressive collection of colour photography.
