I built a fairly small garden railroad three years ago. It is only a circle, about 5x25'. The only structure is a commercially available covered bridge. This is not meant to ba a scale model, just animation for one of the gardens. My wife paints buildings on rocks and, soon, skyscrapers on 6x6 timbers. We want to put acouple of these skyscappers on a hill the trains will tunnel beneath. Before I get to my question, a word about the bldgs. Plexiglass will be cut to fit three sides of the 6x6. Whenshe has sketched the window placement, I will rout the 6x6 to form channels for clear xmas lights. The plexi will be masked so the window areas are covered, the bldg will be painted, the masking removed and the plexi attached to the 6x6, resulting in lighted skyscrapers. OK, the question: I need to make a road on a grade a bottom level grade xing up the hill to the bldgs. What material can I use for the road? The earth has been excavated but I have no clue what to use to simulate either a aspalt or concrete road. While of no help, I have posted the only photo I have of the area, taken two years ago. If it helps I will take some ne wones but the question is only about materials suitable for use. Thanks.
