If you still have this route then you can open the editor, click on the tree and you'll find the xml file and path (without provider and product) in the right flyout. Search your assets folder for this filename. If you don't find it, it could be packed inside an .ap file.
I still have my copy of the BBCL RR - if you have an issue locating yours let me know and I will have a look for the details - can possibly even send the route back if you need it :)
I wont charge too much
ps: looks gorgeous; I could easily see an old turn of the 20th century 4-6-0 RGS just gently poking along. That said, bloody geo blocked content!
I've a good memory for whatever I can remember! If you wait for perfection you will never do anything but it doesn’t stop you wanting it. Age doesn’t stop you, it just slows you down. If you only learn one thing in life - learn to think how your actions and words affect others BEFORE doing or saying.
