Quote from: Woody Elmore on November 27, 2011, 09:46:22 AMdo you think it would still be possible to run On30 on On3 or On3 on On30
On3 track gauge is three quarters of an inch (because American O scale is a quarter inch to the foot.) On30 is the same scale but runs on HO gauge track which is approximately 5/8 of an inch so the On3 is about 1/8th inch wider.
On30 got its start in the 1970s when people began to make models that were O scale but ran on HO track.
