Bear Mountain Pass route

Just really a heads up about this route. I have V5 but I am not sure how long I have had it.
There are two activities with the route but they simply take you from end to end of the main line.
But there are numerous branches into the mountains either side of the pass serving everything from coal mines to a steel works and a timber plantation, and plenty of gradients on the branches.
The main line is only stated to be 35 miles but the branches seem far more than that - though of course mostly slower.
I very much recommend exploring the route. I set up a path to ensure I visited all of it but that is not really necessary.
The only weak point about the route is the mountains which are rather like clones of Egyptian pyramids.
I am still not sure if it a real route or an imaginary one. There is a Bear Mountain but I can find #no mention of a pass.
But great fun anyway as long as you have a head for heights.
