Since starting Selly Oak, I've become a bit of a railway arches nerd. Watching an old episode of The Professionals the other day, I couldn't help looking at the background as they talked by a viaduct.
The screen grab isn't great but these filled in arches look great. Better still, being genuine 1970s ones, they would be perfect for me. Not that I'm going to change anything now, but it shows that watching old telly sometimes counts as research.
