Well, I hate- absolutely hate- being picky like this, but neither set of tunnels, the UK or the ones by Andi06 look good on the route. It's supposed to be a mining/ ore line and the sophisticated stone and brick tunnels don't fit in. Thanks for the suggestion though. However I like Robbie's idea. The only thing about that idea is this: I want to make the route available for download when it's finished, along with its 36 inch counterpart and one other route, and I'm curious as to how I'd get around any permission issues with that one, mainly because there won't be anywhere for anyone to download the altered tunnel. I know I can give the instructions but I want this to be as easy as possible for anyone who gets it. So I guess the main question is: is it okay to take a tunnel, change the track in it, and then post that new tunnel on the DLS, even though it was the original creator who did all the work?
