I acquired a couple of GarGraves S-Gauge Switches and thinking about starting a small layout to see how it compares to O-Gauge. I was searching on eBay for some track, but I’m confused by ‘Standard’ and ‘S-Gauge’. Are they the same? I’m thinking about continuing with GarGraves track since I already have the Switches, but are they compatible with other brands? And what about the trains? I was thinking about buying a set, but my search is coming up with 3-rail and GarGraves is 2-rail so I confused. What should I be searching for?
