Photographer, photographic historian and incurable steam enthusiast, John Hannavy uses his own collection of postcards to explore the rolling stock, stations and operation of the railways in the period from 1902 up to the outbreak of the First World War in 1914. As well as trains in the land- and cityscape, the 290 postcards reproduced include views of the Travelling Post Office, the Snowdon Railway, trackside buildings and railway disasters.
