I am just getting started in model railroading and I would like to know if there is a track layout program for O gauge for the MAC. I have Lionel FastTrack and I want to know how many pieces of track, and what kind to build an outer loop oval and an inner loop figure 8. I have a table that is 15 long by 10 wide, so I think I have enough room. I look forward to the forum's answers. Thanks
