British Railways Locomotives & Coaching Stock: The Rolling Stock of Britain's Mainline Railway Operators and Light Rail Systems: 2014 by Robert Pritchard, Peter Hall (Hardcover, 2014)
Its a book of numbers of trains it has limited interest to all but ardent train buffs its not a great read but it is the source of much information and great photos you'll know if its for you or not. Its a replacement for the old Ian Allan ABC books.
