I see my favorite road in there ...The Rock Island.
when I still had my model railroad stuff, I made a fictitious road called the "New Rock Island" and in the layout it had a route through the Colorado Rockies namely Moffat tunnel and through Leaville and Vail down to Canon city and then out east towards the Kansas border ( not a real route) and I also had a plow and some tunnel motors for extra traction boost in service and a crane. good times with the stuff and a bit of imagination. :D:D
