I need to decide which one of these to work with. One is a 9x9 L the other is a 10x10 L. The final layout will most likely be a 10x10 but I can adapt the 9x9 by adding a few more straits. My main problem is deciding which one to go with. I think the 9x9 looks a little cooler but the 10x10 will let me runn two trains without doing any fancy wiring tricks or constant switching. I fudged a bit on the switches and the 90 degree cross because RTS doesn't have the right ones in thier library and I had to make 'em myself.
