Hung from ceiling. Originally planned on a single track main then decided to double track. As of now planning on a 18"R and 16.75"R. Grade is a little under 2%. No depth really for scenery but may have some foam ledges on inside of curve for scenery. Plywood is 3" wide, planning to have a plexiglass guard around the outside to catch anything that derails. Inside of loop will remain mostly hollow.
