Wikidata

This tag can be used to specify the track width (gauge) of railways.

It is specified in millimetres (mm, 1/1,000 of a metre) as is the railway and tagging practice, e.g. "1435 mm".

As the Standard gauge of 1,435 millimetres (4 ft 8 12 in) is used on most of the world's railways, it is particulary important to add the track width for narrow gauge and broad gauge railways, and it is suggested that mappers concentrate on adding this tag to these railways. However, it is not incorrect to add gauge=1435 to a standard gauge railway.

Why not to use text values

Main article: Verifiability

Some users used gauge=broad, gauge=standard or gauge=narrow tags. Please consider updating these tags with precise information.

Dual gauge tracks

Tracks that support two or more gauges (by using three or more rails) should have all gauges specified using semicolon (";"), no space, as a separator. The smallest value should come first. Example: gauge=1000;1435.
