Four of the layouts are for Atlas track, the rest are only shown with a Lionel Fastrack list of materials. I really don't think it would be that hard to figure out how to build any of these layouts using the track material of your choice. In fact, I think I am going too pick one and build it with Lionel tubular track. It will take a little experimenting and planning, but should come out almost the same when I am done.
