Pete! Thanks! a lot, I've downloaded the program and it is really nice! almost like a few of our programs. Didn't have any problem with install and is in English. G,O,HO,N,TT,Z and it has rok-track in Z. It's pretty easy to use I think the modelers that like using computer might download and use. It also has a nice 3D view of the track that you have laid down.
