Cheers TJ.  Actually I'd been thinking of starting an article on Brunswick Tunnel. The pictures are missing from that link now however there are some here so there are two references to link to as evidence.  But at the moment I'm held up with another job. I'm no expert on trains and tunnels so if you feel like starting the page, let me know and I could weigh in and do just those bits of tidying which prevent new pages from being tagged and deleted. Don't know if you've started new articles yet - but the main tactic to avoid deletion is to have an intro that says "Brunswick Tunnel is a so-and-so and it is notable for so-and-so". We don't have pictures for the article, but we could get a photo of that plaque in Harrogate near Trinity church, and of the island in the road in Harrogate where the tunnel-end is underneath. There is more information here. But no pressure - just thought it might interest you. If nothing else it's a good read. Cheers.
