Hi dpg,
Atlas track is a little easier to find in hobby shops than ScaleTrax, but both are easy get mail order and on-line. If you're interested in seeing all the available track systems in person I would encourage you to attend the TCA meet in York next month. You need to be either a TCA member or you can attend as a guest. At the show you could attend one of my seminars on working with ScaleTrax, attend a seminar on Atlas track in their booth, meet Steve Berniessen (owner of Ross Custom Switches), and there may be another layout design and construction round table in the Orange Hall conference room. It's worth a cross state drive.
