What does HOn3½ mean ??

Some basic definitions.

Do you know the difference between scale and gauge, do you know what standard, broad and narrow gauge mean.?
Scale is the ratio of reduction in size compared to real life.
Gauge is the gap between the rails on the tracks a train runs on. 
HO gauge is an internationally recognised standard with the rails 16.5mm apart. There are other gauge tracks available such as N gauge 12mm, O gauge 32mm and many more......

HOn3½
To more accurately depict a Queensland Narrow gauge train set people have decided on the designation HOn3½ which refers to HO 1/87 scale trains etc. running on N gauge track which is 12mm apart,  3½ refers to the Narrow gauge of 3 ft 6 in = 1067mm 

HO
HO train sets refers to HO gauge tracks (16.5mm) with 1/87 scale Trains etc.

There are a few variation on this like the UK based OO train sets manufactured by Hornby, Dublo etc.

OO
OO train sets refer to HO gauge tracks (16.5mm) with 1/76 scale trains.

GAUGES
In the real world there are different gauges or widths of track, in Australia we have three main gauges.
Broad Gauge is the track width used in most parts of Victoria.   1600mm.
Narrow Gauge is used in Queensland, Tas, WA and parts of SA   1067mm
Standard Gauge refers to the track width used in NSW and later to connect NSW, Victoria and Queensland.   1435mm

To more accurately depict a Queensland Narrow gauge train set people have decided on the designation HOn3½ which refers to HO 1/87 scale trains etc. running on N gauge track which is 12mm apart. 3½ refers to the Narrow gauge of 3 ft 6 in = 1067mm 

I hope this has helped answer your questions.
