Many narrow gauges, from {{Track gauge|15in}} gauge to {{Track gauge|4ft8in}} gauge, are in present or former use. They fall into several broad categories:

===Just under standard gauge===

{{Track gauge|4ft6in}} track gauge (also known as Scotch gauge) was adopted by early 19th-century railways, primarily in the [[Lanarkshire]] area of Scotland. {{Track gauge|4ft6.5in}} lines were also constructed, and both were eventually converted to standard gauge.

{{Track gauge|1067mm}} between the inside of the rail heads, its name and classification vary worldwide and it has about {{convert|112000|km|mi}} of track.

* {{Track gauge|1050mm}} on the [[Hejaz railway]] in Israel, Jordan, Lebanon, Saudi Arabia and Syria; only a few lines survive.

===Metre gauge and Italian metre gauge===
{{main|Metre gauge}}
As its name implies, metre gauge is a track gauge of {{Track gauge|1000mm}}. It has about {{convert|95000|km|mi|abbr=on}} of track.

According to Italian law, track gauges in Italy were defined from the centre of each rail rather than the inside edges of the rails. This gauge, measured {{Track gauge|950mm}} between the edges of the rails, is known as [[Track gauge in Italy|Italian metre gauge]].

===3 ft, 900 mm, and Swedish three-foot gauge===

There were a number of large {{Track gauge|3ft}} railroad systems in North America; notable examples include the [[Denver & Rio Grande]] and [[Rio Grande Southern Railroad|Rio Grande Southern]] in Colorado; the [[Texas and St. Louis Railway]] in Texas, Arkansas and Missouri; and, the [[South Pacific Coast Railroad|South Pacific Coast]], [[White Pass and Yukon Route]] and [[West Side Lumber Company railway|West Side Lumber Co]] of California. {{Track gauge|3ft|disp=1}} was also a common track gauge in South America, Ireland and on the [[Isle of Man]]. {{Track gauge|900mm|disp=1}} was a common gauge in Europe. Swedish three-foot-gauge railways ({{Track gauge|891mm|disp=or}}) are unique to that country and were once common all over the country. Today the only 891&nbsp;mm line that remains apart from heritage railways is [[Roslagsbanan]], a commuter line that connects Stockholm to its northeastern suburbs.

=== 2 ft 9 in gauge ===
A few railways and tramways were built to {{Track gauge|2ft9in}} gauge, including [[Nankai Main Line]] (later [[Track gauge conversion|converted]] to {{Track gauge|3ft6in|disp=or}}), [[Ocean Pier Railway at Atlantic City]], [[Seaton Tramway]] ([[Track gauge conversion|converted]] from {{Track gauge|2ft|disp=1}}) and [[Waiorongomai Tramway]].

{{main|800 mm gauge railways|2 ft 6 in gauge railways|750 mm gauge railways}}

{{Track gauge|800mm}} gauge railways are commonly used for [[rack railway]]s. Imperial {{Track gauge|2ft6in}} gauge railways were generally constructed in the former [[British colonies]]. {{Track gauge|760mm|disp=1}} [[Bosnian gauge]] and {{Track gauge|750mm|disp=1}} railways are predominantly found in Russia and Eastern Europe.

{{main|List of 2 ft 3 in gauge railways}}
Gauges such as {{TrackGauge|2ft3in}}, {{TrackGauge|2ft4in}} and {{TrackGauge|2ft4.5in}} were used in parts of the UK, particularly for railways in Wales and the borders, with some industrial use in the coal industry. Some sugar cane lines in Cuba were {{TrackGauge|2ft3.5in}}.<ref>[https://www.zelmeroz.com/album_rail/ctn/ctn_08.pdf] (2003)</ref>

{{main|2 ft and 600 mm gauge railways}}

{{Track gauge|2ft}} gauge railways were generally constructed in the former British colonies. The [[2 ft gauge railroads in the United States|U.S. had a number of railways of that gauge]], including several in the state of Maine such as the [[Wiscasset, Waterville and Farmington Railway]].  {{Track gauge|1ft11.75in}}, {{Track gauge|600mm}} and {{Track gauge|1ft11.5in}} were used in Europe.

===Minimum gauge===
{{main|Minimum-gauge railway}}

Gauges below {{Track gauge|1ft11.5in|lk=on}} were rare. [[Arthur Percival Heywood]] developed {{Track gauge|15in|lk=on}} gauge [[British narrow-gauge railways#Estate railways|estate railways]] in Britain and [[Decauville]] produced a range of industrial railways running on {{Track gauge|500mm|lk=on}} and {{Track gauge|400mm}} tracks, most commonly in restricted environments such as underground mine railways, parks and farms, in France. Several {{Track gauge|18in|lk=on}} gauge railways were built in Britain to serve ammunition depots and other military facilities, particularly during [[World War I]].
