Gauge refers to the distance between the rails - different gauge models and track have a standard measurement for that gauge between the wheels and rails. However, this is where the difference between scale and gauge becomes important - different scale models can run on the same track if the gauge is the same.
Scale 1:76 gauge 16.5mm
The most popular model rail scale in the UK. As 00 and H0 have the same gauge track, 00 models can run on a H0 layout and vice-versa.
Brands: Hornby
Scale 1:87 gauge 16.5mm
H0 gauge is the most widely used gauge outside the UK. As H0 and 00 have the same gauge track, H0 models can run on a 00 layout and vice-versa.
