Rail gauge is the distance between the inner sides of the two parallel rails that make up a railway track. Sixty percent of the world's railways (prototype 1:1) use a gauge of 1435 mm (4 ft 8½ in), which is known as the standard or international gauge. Gauges wider than standard gauge are called broad gauge, those smaller than standard narrow gauge. [source: Wikipedia]

Some common model railway scales and their corresponding track gauges.

Common Name	Ratio	Scale in mm/ft	Track gauge (mm)
O	1:43.5	7	32
OO	1:76.2	4	16.5
HO	1:87.1	3.5	16.5
N	1:160	1.9	9
Z	1:220	1.4	6

You have Hornby Set track so it is OO scale and 16.5mm track gauge.
