This will allow you to design your own layout. I have a lot of 4x8 track layouts that I have designed with Tracker 2000 and I would be glad to share them with you. However, I tend to focus more on achieving an interesting, unique, and one of a kind layout that I really like with little concern for the track pieces involved. This approach is pretty easy, it just has to fit correctly. The more challenging approach is to design a layout with a specific set of track pieces, say the inventory of pieces that come with a particular race set like the Tomy Super International. Gregory Braun of HOSLOTCARRACING.COM has done a superb job of coming up with compelling layouts that make the best use of the track set pieces that come with popular sets.
