Шаблон:Track gauge/doc

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|al=on|lk=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|Russian gauge}} → 1 520 mm (4 ft 11 ²⁷⁄₃₂ 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.

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!).

• When an input value is not recognised by the template (see last two table examples), 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: 1m is recognised. However, it is not available for all metric defined gauges. Using mm is a safer bet.

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)
wrap=y	Deprecated. The same as nowrap=off. This is the default behaviour, so can be removed without harm.

• 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 gaugfe 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.

Background

There are two maintenance categories under Category:Wikipedia track gauge categories that can help in maintenance of the template.

• Category:Articles using template 'Track gauge' with unrecognized input: input to be checked. No error message on the page, but it needs attention.
• Category:Pages with no gauge entered in Infobox rail line: template {{Infobox rail line}} is used, but parameter |gauge= is empty.

Sometimes an input parameter is not recognised by the template (that is: it is not defined in the internal data list). The article page with this {{Track gauge|some unknown gauge}} is added to the maintenance category (named Category:Articles using template 'Track gauge' with unrecognized input). Interested editors will check that category, and can edit that article page (for a spelling error), or propose to add that track gauge to the template.
