ଛାଞ୍ଚ: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}} → ୧,୫୨୦ mm (4 ft 11 ²⁷⁄₃₂ in)
• {{Track gauge|4 ft}} → 4 ft (୧,୨୧୯ mm)

Extra options are available:

• {{Track gauge|1520 mm|al=on|lk=on}} → ୧,୫୨୦ mm (4 ft 11 ²⁷⁄₃₂ in)

Input options

The first parameter specifies the gauge:

• {{Track gauge|1435 mm}} → ୧,୪୩୫ mm (4 ft 8 ¹⁄₂ in)
• {{Track gauge|4 ft 8.5 in}} → 4 ft 8 ¹⁄₂ in (୧,୪୩୫ mm)
• {{Track gauge|4 ft 8 1/2 in}} → 4 ft 8 ¹⁄₂ in (୧,୪୩୫ mm)
• {{Track gauge|56.5 in}} → 4 ft 8 ¹⁄₂ in (୧,୪୩୫ mm)
• {{Track gauge|Standard gauge}} → ୧,୪୩୫ 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 137 gauges are defined by metric units, and 136 by imperial units. Some are defined in both unit sytems, in both, 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	୧,୪୩୫ mm (4 ft 8 1⁄2 in)	standard gauge
standard gauge	୧,୪୩୫ mm (4 ft 8 1⁄2 in)	standard gauge, by name
4 ft 8.5 in	4 ft 8 1⁄2 in (୧,୪୩୫ mm)	standard gauge, this way puts imperial units first
UK sg	4 ft 8 1⁄2 in (୧,୪୩୫ mm)	standard gauge, this way puts imperial units first
56.5 in	4 ft 8 1⁄2 in (୧,୪୩୫ mm)	standard gauge, by all-inches
56.5"	4 ft 8 1⁄2 in (୧,୪୩୫ mm)	standard gauge, using primes
56 1/2 in	4 ft 8 1⁄2 in (୧,୪୩୫ mm)	standard gauge, using slash for fraction
1 m	୧,୦୦୦ mm (3 ft 3 3⁄8 in)	1 m is recognised, but not many more in m. Better use mm
16.5 mm	୧୬.୫ mm (0.65 in)	HO scale model railway
16.5 in	16 1⁄2 in (୪୧୯ mm)	Miniature railway
7 ft 0.25 in	7 ft 1⁄4 in (୨,୧୪୦ 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!).

• Names can be universal, being defined worldwide. For example: Iberian gauge, ୧,୬୬୮ mm (5 ft 5 ²¹⁄₃₂ in) . Other names can be localor culturally restricted, for example the name "Cape gauge" is used in South Africa for 3 ft 6 in (୧,୦୬୭ 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.

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):

୧,୦୦୦ 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 defined track gauges is limited, and oversee-ablle (today: some 260 sizes, by mm, are defined).

Using {{Track gauge}} allows us to track (follow) all articles with a specific gauge (see the options-list on this page, and Category:Articles that mention a specific track gauge).

Also, the track definition can be directly linked to the sourcing article: ୧,୦୬୭ 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 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 (୦).
