As I mentioned in the other group, I am going to build my new layout with Woodland Scenic foam risers. You can see in the pictures that I have posted that the open grid bench work, which you can't see, is covered with acoustic ceiling tiles. This gives me the flat surface I need without having to cut a lot of plywood sub-roadbed and risers. Not much fun as you probably already know, especially on the curved pieces. And all those risers to cut and the splices to make. The WS system has to be simpler.
Now comes the fun. Figuring out how much and of what pieces I needed. Well, I have a lot of foam coming. The real fun was figuring out the inclined risers needed to allow the proper clearance at the overpasses. I am using two different slopes, the 2% and the 3%, to get up to the clearance I need. What I also had to do was combine several different thicknesses of riser plus incline to get to the proper height.
As soon as I get started and take some pictures, I'll post my progress. Meanwhile, if anyone has questions about the WS foam system, ask away. I think I have a good handle on it.
