I've got nothing. I don't know what this is (OK, it's a steam locomotive), or where it is. Based on the other photos, I'm going to say 1970s, but even that's a guess. Suggestions in the comments please.
Love the hairy rope stopping people wandering over the track, and the rudimentary rolling stock though.
Update: I asked my friend Andrew, editor of Narrow Gauge World, and he suggested, "It's one of the standard Bagnall 0-4-0STs that include the likes of Pixie, Sir Tom et al, but which one is a big question. I'm wondering if it might be the earliest days of Amerton or Threlkeld, or the short-lived line at Crich."
We will keep digging.
