List of track gauges

This list presents an overview of railway track gauges by size.

A gauge is measured between the inner faces of the rails.

There are also some extreme narrow-gauge railways listed.

5 in (127 mm), 5+7⁄10 in (145 mm) and 7+1⁄4 in (184 mm) gauges are all in use on this model-miniature railway.,[1][2] there is also one at Denmark’s railway museum in Odense,[3][4][5] one at the Tramway Museum Skjoldenæsholm, Jystrup, Ringsted,[6] and many other model-miniature railways in Denmark[7][8][9][10] and Model lane Europe, Hadsten, Favrskov[11] and many others.

[12][13][14][15] Railways with a track gauge between 500 mm (19+3⁄4 in) and 4 ft 8+1⁄2 in (1,435 mm) standard gauge.
