ઢાંચો:Track gauge

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

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}} → ૧,૫૨૦ mm (4 ft 11 ²⁷⁄₃₂ in)
{{Track gauge|4 ft}} → 4 ft (૧,૨૧૯ mm)

Extra options are available:

{{Track gauge|1520 mm|lk=on}} → ૧,૫૨૦ mm (4 ft 11 ²⁷⁄₃₂ in)
{{Track gauge|1520 mm|al=on}} → ૧,૫૨૦ mm (4 ft 11 ²⁷⁄₃₂ in) Russian gauge
{{Track gauge|1520 mm|allk=on}} → ૧,૫૨૦ mm (4 ft 11 ²⁷⁄₃₂ in) Russian gauge

Input options

The first parameter specifies the gauge:

{{Track gauge|1435 mm}} → ૧,૪૩૫ mm (4 ft 8 ¹⁄₂ in)
{{Track gauge|4 ft 8.5 in}} → 4 ft 8 ¹⁄₂ in (૧,૪૩૫ mm)
{{Track gauge|4 ft 8 1/2 in}} → 4 ft 8 ¹⁄₂ in (૧,૪૩૫ mm)
{{Track gauge|56.5 in}} → 4 ft 8 ¹⁄₂ in (૧,૪૩૫ mm)
{{Track gauge|Standard gauge}} → ૧,૪૩૫ 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.

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`	૧,૪૩૫ mm (4 ft 8 ¹⁄₂ in)	standard gauge
`standard gauge`	૧,૪૩૫ mm (4 ft 8 ¹⁄₂ in)	standard gauge, by name
`4 ft 8.5 in`	4 ft 8 ¹⁄₂ in (૧,૪૩૫ mm)	standard gauge, this way puts imperial units first
`UK sg`	4 ft 8 ¹⁄₂ in (૧,૪૩૫ mm)	standard gauge, this way puts imperial units first
`56.5 in`	4 ft 8 ¹⁄₂ in (૧,૪૩૫ mm)	standard gauge, by all-inches
`56.5"`	4 ft 8 ¹⁄₂ in (૧,૪૩૫ mm)	standard gauge, using primes
`56 1/2 in`	4 ft 8 ¹⁄₂ in (૧,૪૩૫ mm)	standard gauge, using slash for fraction
`1 m`	૧,૦૦૦ mm (3 ft 3 ³⁄₈ in)	1 m is recognised, but not many more in `m`. Better use `mm`
`16.5 mm`	૧૬.૫ mm (0.65 in)	HO scale model railway
`16.5 in`	16 ¹⁄₂ in (૪૧૯ mm)	Miniature railway
`7 ft 0.25 in`	7 ft ¹⁄₄ in (૨,૧૪૦ 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 (૧,૦૬૭ mm) ૧,૦૬૭ mm (3 ft 6 in)
al=on	Adds the alternate name after the gauge measurement values	`{{Track gauge\|sg\|al=on}}`	૧,૪૩૫ 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}}`	૧,૪૩૫ 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 (૧,૦૦૦ 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}}`	૧,૪૩૫ 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}}`	૧,૪૩૫ mm/4 ft 8 ¹⁄₂ in
disp=[]	Uses a square brackets rather than parentheses	`{{Track gauge\|sg\|disp=[]}}`	૧,૪૩૫ mm [4 ft 8 ¹⁄₂ in]

disp=br	Forces a line break after the first size (and also before any gauge name)	`{{Track gauge\|sg\|disp=br}}`	૧,૪૩૫ 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}}`	૧,૪૩૫ mm (4 ft 8 ¹⁄₂ in)
addcat=no	Will not add a maintenance category	`{{Track gauge\|sg\|addcat=no}}`	૧,૪૩૫ mm (4 ft 8 ¹⁄₂ in)
unitlink=on	Adds wikilinks to the measurement unit labels	`{{Track gauge\|sg\|unitlink=on}}`	૧,૪૩૫ mm (4 ft 8 ¹⁄₂ in)

Names can be universal, being defined worldwide. For example: Iberian gauge, ૧,૬૬૮ 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 (૧,૦૬૭ 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)

For articles written in US-English, it is possible to set parameter |engvar=en-US. In this situation, the US-English spelling is shown (metER):

{{track gauge|1000mm|allk=on|engvar=en-US}} → ૧,૦૦૦ mm (3 ft 3 ³⁄₈ in) meter gauge

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: ૧,૦૬૭ 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 (૦).
