This book, covering the early years of diesel on Britain's railways, presents a wonderful array of over 200 colour photographs, many of them previously unpublished. All the imagery is reproduced from original transparencies that have remained carefully preserved away from daylight since the day they were taken, so the original vividness of colour remains - a rare quality. As high-quality colour photography from this period is scarce (most photographers worked mainly in black and white to serve the needs of publishers), this book will delight today's railway enthusiasts, who are always keen to see new material unearthed and published.
