After the end of steam on BR (August 1968) quite a few of us switched our attention to the remaining – and very extensive – industrial railway networks. They were mostly colliery lines, operated by the National Coal Board (NCB). Attention switched from Bolton loco shed to Walkden Yard and Astley Green. But I got further afield too. Places like Maerdy, Talywain, Philadelphia, Methil, Polkemmet, Haig, Gresford and West Cannock became familiar, including the pit canteens where I was always made welcome and fed well! Very glad I managed to get to them.
