How interesting. He did indeed have a railway background! Not that he was an engine driver or anything like that. He left school at 14, although I suspect he rarely went prior to that, and went to join his father on the railways. However, he had nothing to do with engines at all and worked with the horses! I guess by the time he joined up at 22 there were fewer of them because his occupation was given as a porter. I suppose he had marginally more experience of the railways than someone who came from, say, an agricultural background.
