This is Chur in Switzerland, on a cold evening in February 1977. Yes, that is a train running down the road, and this is a sight you can still see today, although the track has been doubled in the town itself.
I'd been Interrailing and this was one of those iconic locations I'd planned to visit. The branch line up to Arosa is very spectacular and soon after leaving Chur runs into deep snow. But this was my favourite stretch of the line, the incongruity of long trains running down the road still a novelty.
This was very different from home back in Littlehampton, I was just twenty and couldn't speak a word of German, so it all seemed very foreign. It's very familiar to me now of course, having visited (and lived) in Switzerland many times since!
