HI...I am right in thinking Gauge 1 is the same as G Gauge with regard to track measurements?
The GAP between the rails is the same, but Gauge 1 track is a scale model of the standard 4' 8.5" rail. Rail height is measured in hundredths of an inch, and called 'code'. Much Gauge 1 track is Code 180. So-called G gauge track is modelled on narrow-gauge track and is far more robust, much measures .332", or Code 332. LGB and Piko comes to mind.
All my track is Tenmille so-called G scale track, and everything I have, from G1 to 7/8ths, runs on it without a problem, but then I don't have ANY points to cross.
