Thanks for reviving this thread!

Hey, would anybody be interested in getting the ball rolling with the RWA route and lay the very first tracks?
What do you say about this terrain?

The area highlighted in orange might be able to meet everybody's demands: it has some mountains, some twisting canyons, some gentle slopes and rolling terrain, and also quite a lot of more or less level terrain to build larger yards and cities on.
I would be happy to (Re)DEM this terrain in hi-res and then send it to who ever wants to begin building the route.
What do you say?
Cheers,
Michael
