Looking Back at Class 40 Locomotives is a full-colour photographic album depicting an iconic locomotive class in a variety of settings. While most classes of locomotive have their own devotees, it must be said that Class 40s still command an impressive following even after two decades. While only seven of the original 200 Class 40s survive physically, this book pays tribute to the whole class in a wonderful collection of photographs, along with captions that draw the readers attention to details that might previously have been missed. A varied selection of locations and workings have been chosen from a vast library of colour photographs, which are accompanied by informative captions; they are sure to appeal to both the enthusiast and the modeller alike.
