Shortly after reversing at Bedford, 47016 Atlas passes Ampthill (Millbrook) on 2 November 1994 with the 4C51 10:45 Forders Sidings to Cricklewood empty binliner. Without the luxury of today's ten frames per second cameras, I'm amazed that I managed to take this at exactly the right moment, in the very small gap between the mast and the leaning milepost. There was also of course no way of being totally sure beforehand that the gap was big enough for a Class 47!
