Peter J Green's interest in railways really began in 1959 during a holiday near the former Great Western main line in Devon. At first his hobby was about collecting numbers but, encouraged by his father's interest in photography, he soon began to record the general railway scene. His focus was on steam locomotives initially, but quickly expanded to include diesels, signalling and railway infrastructure. Pursuing what has been an absorbing interest, he has recorded the trains, and the railways on which they run, not only in Great Britain, but also in many other parts of the world. Today he continues to travel and photograph railways as often as he is able to do so.
