I've just got back from Primrose and I've got a few photo's to stick up in a short while.
It was quite comical, as I asked the Warden, "do you know where the old railway station is?"
W: "No, sorry, never heard of it"
M: "well, I've seen some photo's of an old railway station and there is a tunnel under the road that used to link to this site"
W: "Ahhh, now that's interesting, because a hole has opened up over there just behind my caravan, I wonder if that's it"
M: "well, if you don't mind, I'll go have a wonder about"
W: "let me know if you find anything, as I'd like to take a look"
So when I got back after a walk around the station and the tunnel, I showed the pictures to the warden. You can see the light coming in from the hole at the end of the tunnels now, so hopefully they'll fill it in before some kids fall down it !!!
