Whew! I was about to post about the G scale "guess what scale this is?" morass, and it's resemblance to On30. ....somebody beat me to it, but l don't have a dog in that fight, anyway. If l ever get around to it, l wanted to add an On3 interchange shortline to my three rail. I do NOT want to have to modify every loco and replace expensive trucks (if can be found) on every car. To not provide both gauges is a missed marketing opportunity for On30 mfrs., and for Atlas? not to offer On3 track. So says one side of my head. The other says 4'8 1/2" is a thousands of years old Roman arbitration, anyway, and only metric gauges have any scientific base. Oh, there was a 2' Colorado' road serving Central City mines, so not confined to Maine (and l bet others).
