Never heard of this manufacturer so looked them up on Ebay. The scenery is printed on 80lb card stock. Though it does not matter for roads, thing is wrt stuff like the rock cliffs I don't know if the design is three dimensional or flat. If I did buy the roads I would cut off the green borders and just use the roads.
There are a lot of modelers who swear by printed cardstock buildings for background flats.
The old timers like Frank Ellison in the 30-50's built some of their buildings from cardstock and with paint, pencils, chalk etc. made them look good. I never saw one in person but in the old black and white photos in the magazines they looked very real. There are companies today who sell card stock kits with paper for siding.
Perhaps buy the smallest amount you can and see how it looks on your model RR.
