British Railways Past and Present - a nationwide series of books featuring photographs of railway locations taken several decades ago and comparing them with the same scene today. Such is the current pace of change on our railway system that even a few years can reduce a busy and vibrant railway scene to a wasteland or housing estate - or conversely can bring electrification and up-to-the-minute technology to an outdated, run-down route. The contrasts are often dramatic, while sometimes hardly anything has altered in 30 or 40 years.
