Template documentation[view] [edit] [history] [purge]

This template is used on approximately 24,000 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them.

This template uses Lua:

This template accepts a track gauge and returns that defined track gauge well formatted, plus the converted size value by another unit:

((Track gauge|1520 mm)) → 1,520 mm (4 ft 11+27⁄32 in)
((Track gauge|4 ft)) → 4 ft (1,219 mm)

Extra options are available:

((Track gauge|1520 mm|lk=on)) → 1,520 mm (4 ft 11+27⁄32 in)
((Track gauge|1520 mm|al=on)) → 1,520 mm (4 ft 11+27⁄32 in) Russian gauge
((Track gauge|1520 mm|allk=on)) → 1,520 mm (4 ft 11+27⁄32 in) Russian gauge

Input options

The first parameter specifies the gauge:

((Track gauge|1435 mm)) → 1,435 mm (4 ft 8+1⁄2 in)
((Track gauge|4 ft 8.5 in)) → 4 ft 8+1⁄2 in (1,435 mm)
((Track gauge|4 ft 8 1/2 in)) → 4 ft 8+1⁄2 in (1,435 mm)
((Track gauge|56.5 in)) → 4 ft 8+1⁄2 in (1,435 mm)
((Track gauge|Standard gauge)) → 1,435 mm (4 ft 8+1⁄2 in)

Rail track gauges can be entered as they are defined: in units mm or ft in. Also common accepted names can be used, see below.

The input value (a length, in metric or imperial units) must be a defined track gauge. Currently 135 gauges are defined by metric units, and 148 by imperial units. Some are defined in both unit systems, such as the standard gauge.

When an input value is not recognised by the template, the template simply returns the input as it is: ((Track gauge|25in)) → 25in

The page with this unknown input is also listed in a maintenance category, in the background, that signals interested editors that there is a new rail gauge used in Wikipedia. More on this below.

Some gauges in metric are defined in metres: 1 m is recognised. However, it is not available for all metric defined gauges. Using mm is a safer bet.

List of defined track gauges

This table:

Track gauges in bold font are definitions. Track gauges in regular font are merely conversions (calculations).

Formatting input

When entering a track gauge (like ((Track gauge|1435mm)), these are formatting options. Keep in mind that only defined gauges are recognised.

Spacing is free, and fractions can be used in imperial units. Primes (' and ") may be used for [foot, inch]. Any [foot, inch] size can be entered in all-inches (4 ft 8 1/2 in equals 56 1/2 in and 56.5 in).

Input options, examples
Parameter input	Result	Note
`1435 mm`	1,435 mm (4 ft 8+1⁄2 in)	standard gauge
`standard gauge`	1,435 mm (4 ft 8+1⁄2 in)	standard gauge, by name
`4 ft 8.5 in`	4 ft 8+1⁄2 in (1,435 mm)	standard gauge, this way puts imperial units first
`UK sg`	4 ft 8+1⁄2 in (1,435 mm)	standard gauge, this way puts imperial units first
`56.5 in`	4 ft 8+1⁄2 in (1,435 mm)	standard gauge, by all-inches
`56.5"`	4 ft 8+1⁄2 in (1,435 mm)	standard gauge, using primes
`56 1/2 in`	4 ft 8+1⁄2 in (1,435 mm)	standard gauge, using slash for fraction
`1 m`	1,000 mm (3 ft 3+3⁄8 in)	1 m is recognised, but not many more in `m`. Better use `mm`
`16.5 mm`	16.5 mm (0.65 in)	HO scale model railway
`16.5 in`	16+1⁄2 in (419 mm)	Miniature railway
`7 ft 0.25 in`	7 ft 1⁄4 in (2,140 mm)	Brunel
`2140 mm`	2140 mm	Not recognised (so no converted value). This track gauge, Brunel's, is not defined in mm.
`65 in`	65 in	Input not recognised (so no converted value); output copies the input. This is a good way to enter an uncovered rail gauge on a page: other editors will notice (and can add a new gauge to the template!).

Optional parameters
Parameter	What it does	Example (code)	Example (output)
lk=on	Links the defining measure (first measure) "defined size" depends on input	`((Track gauge\|3ft6in\|lk=on))` `((Track gauge\|1067mm\|lk=on))`	3 ft 6 in (1,067 mm) 1,067 mm (3 ft 6 in)
al=on	Adds the alternate name after the gauge measurement values	`((Track gauge\|sg\|al=on))`	1,435 mm (4 ft 8+1⁄2 in) standard gauge
allk=on	Adds a wikilink to the alternate name where applicable	`((Track gauge\|sg\|allk=on))`	1,435 mm (4 ft 8+1⁄2 in) standard gauge
first=imp first=met	Puts the requested measure first (metric, imperial)	`((Track gauge\|1000mm\|first=imp))`	3 ft 3+3⁄8 in (1,000 mm)
disp=any text	The text will be written between the measurements, two spaces added. Brackets are omitted. Text must be 2 characters or more. (codes for `\|disp=` are processed as described: 1, s, /, br).	`((Track gauge\|sg\|disp=also defined as being))`	1,435 mm also defined as being 4 ft 8+1⁄2 in
disp=s or /	Uses a slash as a separator rather than parentheses	`((Track gauge\|sg\|disp=s))`	1,435 mm / 4 ft 8+1⁄2 in
disp=[]	Uses a square brackets rather than parentheses	`((Track gauge\|sg\|disp=[]))`	1,435 mm [4 ft 8+1⁄2 in]
disp=1	Only shows the first measure (may be used when repeated on a page or in conjunction with `first=` to display the output only)	`((Track gauge\|sg\|disp=1))`	1,435 mm
disp=br	Forces a line break after the first size (and also before any gauge name)	`((Track gauge\|sg\|disp=br))`	1,435 mm (4 ft 8+1⁄2 in)
nowrap=off (default), on, all	Sets possible line break (line wrap): after between the measurements (off=defalt), not (on, all), or not at all when named gauge is present. (note: until May 2014, default behaviour was no break between the measurements. This has changed.)	`((Track gauge\|sg\|nowrap=on))`	1,435 mm (4 ft 8+1⁄2 in)
addcat=no	Will not add a maintenance category	`((Track gauge\|sg\|addcat=no))`	1,435 mm (4 ft 8+1⁄2 in)
unitlink=on	Adds wikilinks to the measurement unit labels	`((Track gauge\|sg\|unitlink=on))`	1,435 mm (4 ft 8+1⁄2 in)

Names can be universal, being defined worldwide. For example: Iberian gauge, 1,668 mm (5 ft 5+21⁄32 in) Iberian gauge. Other names can be localor culturally restricted, for example the name "Cape gauge" is used in South Africa for 3 ft 6 in (1,067 mm), but not in Japan (in Japan that same track gauge is not named).
Also, two sizes can lead to one gauge name.

Named gauges

Established gauge names can be entered. The word "gauge" can be omitted. Case-insensitive (A=a). See also the |al=, |allk= parameters (below), to show a gauge name in the outcome.

English variant (ENGVAR)

This template defaults to UK-English. For articles written in US-English, set parameter |engvar to |engvar=en-US. In this situation, the US-English spelling is shown:

((track gauge|1000mm|allk=on|engvar=en-US)) → 1,000 mm (3 ft 33⁄8 in) meter gauge

As of 2016, the only two gauges impacted are the 1000 mm and 1009 mm gauges. In UK-English these are spelled metre, in US-English these are spelled meter.

Why not use ((Convert))?

To convert a track gauge, using ((Convert)) comes to mind. For example, standard gauge:

((Convert|1435|mm|ftin|abbr=on)) → 1,435 mm (4 ft 8.5 in)

However, this has some disadvantages. First of all, track gauges are defined by an institute, not just measured. The list of those defined track gauges is limited, and overseeable (today some 270 physical sizes are defined).

Using ((Track gauge)) allows us to track (follow) all articles with a specific gauge. This way the list can be made more accurate, correct and complete.

Also, the track definition can be directly linked to the sourcing article: 1,067 mm (3 ft 6 in).

Further more, the template allows to recognise named gauges such as "Russian gauge".

Tracking category

((Track gauge)) detects that an undefined gauge is entered, and signal the page for maintenance. For example, metre gauge is only defined in metric. Entering an imperial size would categorise that article in Category:Articles using Template:Track gauge with unrecognized input (14).
