Alongside Gn15 other modeling scales have developed to cover both the modelling of minimum gauge lines in scales smaller than G, and 'miniature' lines (less than ) in G scale. O9 or On15 is the use of N gauge track in 7mm scale to represent a 'minimum gauge' line. In comparison, GNine is the use of 9mm track to represent 'miniature' lines. GNine is a 'flexible' term for scale, referring to modelling using garden railway scales and
