Remove 783 mm gauge
I propose to remove the 783 mm gauge from the definitons list. As the sourcing article HOn30_gauge explains, this is just a theoretical (prototype) gauge. Such a theoretical gauge is the reaul of a calculation of model gauge &frasl; model scale (the reversed way). -DePiep (talk) 19:45, 16 August 2017 (UTC)
 * "theoretical prototype gauge" explained
 * 1. Regular determination of a model gauge is as follows (prototype gauge = real life gauge):
 * prototype gauge &times; scale = model gauge
 * standard gauge &times; HO scale = model gauge
 * &times; 1:87.1 = 16.5 mm
 * So 16.5 mm is the result (rounding effects are omitted here).
 * 2. Now on that same physical model gauge we can reverse-calculate with a different scale, that results in a different prototype:
 * ? gauge &times; OO scale = 16.5 mm model gauge
 * With OO scale being 1:76, we find prototype gauge:
 * &times; 1:76.2 = 16.5 mm model gauge
 * Since the 4 ft 1 1⁄2 in gauge exists in RL, this is OK. (so the modeling uses two scales, which both result in gauge-fitting rolling stock, but they'll look unnaturally different when riding with each other on the same model track).
 * 3. However, the reverse-calculation can also lead to a non-existing gauge:
 * H0e scale is 1:87, defined as 9 mm model gauge (from prototype 760 mm, rounded toward the definition).
 * Actual prototype would be:
 * ? prototype &times; 1:87 = 9 mm
 * 783 mm &times; 1:87 = 9 mm
 * That prototype does not exist in real life, so it is theoretical only. Therefor it should be deleted from the list of definitions. (There are dozens of model gauges & scales to combine that would lead to multiple dozens of such theoretical gauges). -DePiep (talk) 09:20, 19 August 2017 (UTC)

Track gauge 1,200 mm
should perhaps be linked to Narrow-gauge railway instead of to Appenzell Railways. Peter Horn User talk 04:36, 19 August 2017 (UTC)[[:Category:
 * Even better would be to move the four foot coverage from "narrow gauge" to standard gauge. The early 4' and 4'6" railways weren't a "narrow gauge", they were simply a lack of agreement this early as to what the "standard" would become. Their history is more closely related to early railways than to the two-decade-later beginnings of a deliberately-narrowed loco-hauled edge-railway. Andy Dingley (talk) 08:01, 19 August 201

/Narrow-gauge_railway#Four_foot_and_1200_mm_gauge7 (UTC)
 * I can understand this moving it out of 'narrow gauge'. However, I don't think it should be in standard gauge, because it is not related to it (unlike, for example, near-s.g. tracks that are actually connected to true s.g. somehow). New grouping article like "Non-narrow-gauge narrow gauges" needed? (well, something more serious then but you get the idea). -DePiep (talk) 08:45, 19 August 2017 (UTC)
 * BTW, itself does not use the "narrow gauge", "s.g.", "broad gauge" classifications at all. (The documentation only has rough assumption, internally). So if the 1200 mm sourced definition is moved to an other article,  will follow by changing the link. The move Andy mentiones (out of "narrow gauge" class) is relevant for content articles & categories. Better discuss there, or at WT:TRAINS? -DePiep (talk) 08:50, 19 August 2017 (UTC)


 * Reply to : The problem with Narrow-gauge railway is that there is no source in there (a source that proves that the gauge was defined once). Appenzell_Railways has that source. So once Narrow-gauge railway has a source in there, we can link to that article (which of course would be better for being generic). -DePiep (talk) 09:47, 19 August 2017 (UTC)
 * Then copy the source from Appenzell_Railways to Narrow-gauge railway. At any rate the individual articles listed probably have a source. If not then the link in the template should go directly to the section Appenzell_Railways. Peter Horn User talk 11:30, 19 August 2017 (UTC)
 * Yes someone could do that. Soundest is to add both article link Appenzell_Railways and its source to the 1200 mm article. -DePiep (talk) 13:57, 19 August 2017 (UTC)
 * The template is fully protected. Only someone with access can change the link there. Peter Horn User talk 17:27, 19 August 2017 (UTC)
 * Yes, . The template is complicated & sensitive (for wrong data), so it is protected. But as you know from this talkpage, all proposals are discussed very seriously. When a discussion concludes, the template will be changed (by me, often). Peter, this is why this enwiki list of well-defined track gauges is so very great & stable & trustworthy & well-sourced. And of course, you are one of those who contributed heavily to that greatness. -DePiep (talk) 20:42, 19 August 2017 (UTC)

2 ft 2.5 in: projected gauge only
This gauge seems to be sourced (cannot check), but by saying it was proposed, not build. No need to add to the list then, just use. -DePiep (talk) 13:59, 8 September 2017 (UTC)
 * Following on to this, it's quite right that this was a proposed gauge for the Corris Railway which was actually built to gauge. But I think there were a small number of industrial railways n the UK that did use this gauge - particularly underground in coal mines. Let me see if I can confirm and source that. If my recollection is correct, then it might be worth adding this gauge to the template. Railfan23 (talk) 22:50, 9 September 2017 (UTC)
 * Yes, when sourced there sure will be an article that should have that gauge + source (maybe a list), and then it can be added to the template. -DePiep (talk) 15:50, 22 September 2017 (UTC)

4 ft 8 in wl target?
Why does George Stephenson's original Stephenson gauge link to the very minor, and twenty years later, New Orleans and Carrollton Railroad? Rather than Killingworth Colliery railway, or somewhere more normative? Andy Dingley (talk) 00:03, 15 April 2018 (UTC)
 * We want to link to an article that has the source (reference) for a gauge definition. When multiple articles apply, of course we use the first/original/institutional definition article.
 * wrt changing to Killingworth Colliery railway: that link has some issues. The section it Redirects to has one dead link, and the actual source for this gauge is a book (I can not check). IMO this is a bit below standard ;-). If someone could shape it up, check & fix sources, use Cite nicely, replace "world famous" with the reason of this being famous, maybe make it a stand-alone article (stub), wouldn't that be inviting? Of course the essence (being the origin of s.g.) is huge. - DePiep (talk) 10:09, 15 April 2018 (UTC)
 * A link to George Stephenson or Killingworth locomotives (that could be a target for the Killingworth Colliery railway redir) would be fine, ideally to a section specifically on gauge. But it ought to be related to the origin, and to Stephenson's early work, before his son's extra half inch. Andy Dingley (talk) 12:29, 15 April 2018 (UTC)
 * Which one has the right or best source for this 4 ft 8 in? That is actually my main concern wrt this topic. Could be in Killingworth Colliery railway all right, but better have it right. - DePiep (talk) 12:54, 15 April 2018 (UTC)

Decimals: Comma or Dot?
I was recently browsing some pages on rolling stock in New South Wales, Australia when I noticed that the decimal place indicator was a comma in the Guage field of the train Infobox, while length, width, and height use a dot. This struck me as inconsistent. Is there any reason why this is so? Could this be made more consistent? JonsterMonster (talk) 22:23, 9 July 2018 (UTC)
 * MOS:DECIMAL. English always uses a dot, never a comma. oknazevad (talk) 00:06, 10 July 2018 (UTC)
 * So why does this template use commas? Seems like it should use dots. JonsterMonster (talk) 03:15, 12 July 2018 (UTC)
 * You mean like in ? This is the thousands-separator, described in MOS:DIGITS. A decimal point is used in . Which article(s) were you looking at?
 * If this comma should be optional (alternatives are in MOS:DIGIT), please note. - DePiep (talk) 06:00, 12 July 2018 (UTC)
 * OK, yes I'm stupid. I read it as decimal metres, but it says mm. JonsterMonster (talk) 11:09, 12 July 2018 (UTC)
 * Well, it could be that en-Australian language articles (see local language articles) do not use that comma, and prefer a small space instead ("1&thinsp;000 mm"). If that should be an option in Track gauge, it can be proposed here. - DePiep (talk) 16:06, 12 July 2018 (UTC)

12.5 inch miniature gauge

 * Source does mention it, but why would a company start a new gauge (*next to existing, common gauges)? Could it nbbe the source was sloppy? See also - DePiep (talk) 10:38, 15 April 2018 (UTC)


 * This is an unique gauge (nowhere else used or mentioned). The source here is The Railway Age, July 1, 1898., which indeed mentions that gauge. However, it is strange that for this one track (6 locomotives) the company would create a new gauge, while they also build the common  (of $1/8$ inch difference). In other words, it may very well be that the $12 1/2$ in the source is a miswriting.

disp=s, slash separator and spacing
Should disp&#160;s, i.e.  generate any space around the backslash separator?

At present there's no spacing and it's hard to read, the two terms running closer together than even their numerals and units: Thin space

Particularly where, as for 5 ft 6 in gauge railway, it's bolded as an article title:  Andy Dingley (talk) 12:29, 9 January 2019 (UTC)
 * Looking at Convert. The / slash is not available by default, but can be used:
 * &rarr; 5 ft
 * However, you may have a point. Would thin space help?
 * 5 ft 6 in /&#x200b; 1,676 mm
 * 5 ft 6 in &thinsp;/&thinsp; 1,676 mm
 * 5 ft 6 in /&#x20; 1,676 mm
 * (not the best way to compare, better inline. Anyway, I'd definitiely make the first space NBSP, so that a linebreakl may occur after the slash). -DePiep (talk) 16:22, 9 January 2019 (UTC)
 * So would this be better as a fix to Convert itself? Andy Dingley (talk) 16:37, 9 January 2019 (UTC)
 * does not use Convert internally, all gauge values are hardcoded in the list (the ~275 gauges &times; 2 metric/imperial), and internally formatted stealing from Convert. I'm looking at Convert because it is good to keep similar formatting &tc.
 * Asking for input here, especially for the visual/typographical aspect you mention. (There might be older considerations I'm not aware of). -DePiep (talk) 16:46, 9 January 2019 (UTC)
 * Also, shouldn't any linebreak be before the slash? Andy Dingley (talk) 17:08, 9 January 2019 (UTC)

In convert,  was removed in November 2014. That link shows an example of how it looked before removal: "55 miles / 89 kilometres" with a non-breaking space before the slash. Convert still allows a slash in a range as requested for high/low temperature ranges which is apparently standard for weather reports (September 2016). In case it's of interest, following is an example showing the exact wikitext output by convert for 83&thinsp;/&thinsp;63 °F (28&thinsp;/&thinsp;17 °C): 83 / 83&amp;thinsp;/&amp;thinsp;63&amp;nbsp;°F (28&amp;thinsp;/&amp;thinsp;17&amp;nbsp;°C) Johnuniq (talk) 04:27, 10 January 2019 (UTC)
 * That no-slash discussion is here in the Convert Archives. Problematic situation is "570 mph/917 km/h; 495 kn". In track gauge, the "km/h" does not occur, but double-meaning of slash does: "2 ft 1⁄8 in/613 mm".
 * While we allow the slash value-separator in, we better add spaces to strengthen the right visual grouping:
 * 5 ft 6 &#x005B;in /&#x200b; 1,676&#x005D; mm
 * &#x005B;5 ft 6 in&#x005D; / &#x005B;1,676 mm&#x005D;
 * Wrapping (soft newlines) tbd. -DePiep (talk) 08:25, 10 January 2019 (UTC)


 * Changed in sandbox. See demo in /testcases. Fine with me.
 * For OP example :
 * The new space after the slash is a soft line break option. OK? -DePiep (talk) 11:10, 24 January 2019 (UTC)

 * No re 'probably becasue'. TE editors did not work following the queu, they obviosly skipped the easy ones. Is what I asked about. -DePiep (talk) 00:42, 8 October 2019 (UTC)
 * Obviously your perception of what is easy differs from the perception of the TEs who skipped your request. Your expectation that requests will be handled in a specific order is not realistic and, as far as I'm aware, doesn't apply to any queue on the wiki. Cabayi (talk) 09:55, 8 October 2019 (UTC)
 * I wrote "easy" because the requested edit did not invoke further questions or research by any TE. As for "leap in the dark": it was tested. wrt the order: except that one could expect older requests may be looked at first. All in all this is what caused my question. -DePiep (talk) 10:12, 8 October 2019 (UTC)
 * I think we've had this discussion before. I accept you've tested it to your satisfaction, that you're a competent template editor. BUT... Where could I see the effect tested? Where in your request did you point to any testing for me to validate the change for myself before making it? Cabayi (talk) 10:51, 8 October 2019 (UTC)
 * The consensus section I linked to has a box saying "Currently in sandbox: 2 ft 3 1⁄2 in (699 mm)". Anyway, if such testing were an issue for TE's passing by, why not simply ask for it? The primary requirementrs are: showing consensus, and be clear about the change&mdash; both were served here IMO. wrt your reference to an earlier discussion we had: that was about a different issue in an edit request.

 * I have copies of several Cassier's Magazines myself, but after some searching I found the article online as well. You can read it here. It says "the rails are laid to a gauge of 3 feet 8 inches, and the larch sleepers are placed at about 6 feet pitch..." starting at the bottom of the right-hand column on page 68. The Mirror Cracked (talk) 13:52, 8 October 2019 (UTC)
 * A note on the engineering-timelines.com source. It is not entirely reliable. While it has a lot of good information, it doesn't fully source its information, and it is user-generated content - I don't think there is any editorial control. I've found several instances of factual errors on it, and I treat it with caution. That said sources do disagree about the track gauge of the Cliff Railway. The Cassier's article could be a typo - though you would think the chief engineer of the line would be keen to get that sort of detail right. It is even possible that it was originally 3ft 8in and was slightly gauge widened when the modern concrete sleepers were put in. The Mirror Cracked (talk) 19:28, 8 October 2019 (UTC)
 * Interestingly, Martin Easdown's 2018 book give 3ft 8in as the gauge for the Clifton Rocks Railway, not 3ft 2.5in: . I've also found another paper by Marks given to the Institute of Civil Engineers which again quotees 3ft 8in for the gauge of the Lynton Cliff Railway. This to me makes it less likely that the 3ft 8in is a typo. It would appear that Marks at least thought it was a 3ft 8in gauge line. The Mirror Cracked (talk) 02:01, 9 October 2019 (UTC)

Template-protected edit request on 23 February 2021 – Australian broad gauge
Reason for changing "Victorian broad gauge" to "Australian broad gauge"

1600 mm (5ft 3in) gauge exists in the Australian states of Victoria and South Australia (and, now trivially, existed in Tasmania in the 19th century). Australia-wide, the broad gauge is not known as "Victorian broad gauge" but simply "broad gauge". Victoria has no special claim to the "Victorian" nomenclature on the basis of history or any other reason. Changing the term to "Australian broad gauge" would recognise the common usage and the fact that it does not exist solely in Victoria.

Consequent suggested changes

In the "List of defined track gauges" table, in the 1,600 mm row:
 * column 3: change "Victorian broad gauge" to "Australian broad gauge".

Similarly, in the "Named gauges" table: SCHolar44 (talk) 04:34, 23 February 2021 (UTC)
 * column 1: change to
 * column 2: change "1,600 mm (5 ft 3 in) Victorian broad gauge" to "1,600 mm (5 ft 3 in) Australian broad gauge".
 * It sure would help to have some citations at the linked page. Do you know of any? Also, why not just call it "broad gauge", as indicated in the target article, to be inclusive of Brazilian usage as well? – Jonesey95 (talk) 05:42, 23 February 2021 (UTC)
 * (ec) We should only use names that are actually used as such, not descriptive terms. Despite "Victorian" being a misnomer, as you say, is it not used? And "Australian broad gauge", is that used in sources? -DePiep (talk) 05:45, 23 February 2021 (UTC)
 * Jonesey95, I have added a citation to the bullet point relating to Australia on the linked page. Re your question, "why not just call it "broad gauge?", I guess it's simply that it's a relative term: unless a context is put on it, the term would mean different things to different people – e.g. 5ft 6in on the Indian subcontinent and 1668mm in Spain – hence ambiguous. That said (and the following also addresses DePiep's comment), I can say very confidently that someone in Australia with an interest in railways, when asked, say, "What gauge was the line from Melbourne to Albury before it was standardised?", would reply, "It was broad gauge". And similarly, "Were the railways in the Adelaide suburban area standardised when the interstate routes were?", the reply would be, "No, it's still broad gauge." The terms "Victorian broad gauge" (as currently in the article) and "South Australian broad gauge" would simply never be used. And "Irish gauge" is not used in Australia either. To explicitly answer your 2nd question, De Piep, you would only find the term "Australian broad gauge" used by Australians in a discussion of multi-national gauges, so a published source would be as rare as hen's teeth. I'll browse some old magazines and books and ask my mates to look for one, but I won't hold my breath. ;-) It makes sense to me, as mentioned at the beginning, to add "Australian" solely to establish context among other nation's alternative understandings for the term.

 * Current working:  &rarr;
 * Request (demo):  &rarr;  Australian broad gauge


 * About "Victorian": So actual uasage (as a track gauge name) is disputed in OP. If no sources are found that supports this name (today or historically), it must be deprecated & removed indeed. Of course it might be regional, pertaining to Australia and in now way in Ireland for example. (I recall, from initial days of, this 'source' requirement was not this hard, so Victorian might have entered from habit).
 * About "broad gauge": Not useful havng this as input option: it contains dozens of gauges (all &gt;). However, in an article section it is usable, to make nice sentences: "AU has, a broad gauge. The broad gauge was introduced ... etc.".
 * About "Australian gauge": To make this a recognised name in (as are, nowadays: Victorian, Iberian, Ohio, Russian, etc.), we need sources RS that use this as a name (not as a description). It could be historical (only used in certain era). Best would be, like, an order of a rail road company: "We order this rolling stock with Australian gauge" :-) If these sources can not be found, this signals that "Australian" has not been used as such, and so is not acceptable here. (I understand here in current ref#6, R. Fitch, might be helpful but does not use it; I cannot access the book). In this case too, I  note that a colloquial name as "Australian gauge" can be introduced in text, with less sourcing requirements, and improve the article's info & legibility.
 * So: two topics to find sources for, I don't have the time & knowledge to do so these days. HTH. -DePiep (talk) 19:29, 23 February 2021 (UTC)


 * Hello DePiep, I laughed out loud at the notion of a colloquial name of "Australian gauge" -- not in any way at you, I assure you, just at how it shows up Australia's tragic railway history. The logical concept of one Australian gauge is the very antithesis of what happened with three main gauges that persist today, ignoring the minor ones – which people overseas can barely conceive of. Here's a comment by a former railways commissioner (=president or CEO):
 * Australia’s rail gauge mess has been nothing short of disgraceful, and it is to the everlasting discredit of those responsible. It has been a farrago of procrastination, parochialism, interstate jealousies and political bloody-mindedness. All this capped off by hindrance on the part of Canberra-insulated public servants whose function appeared, for the most part, to be confined to paper shuffling but who, despite their remoteness from the action, sought to impose their obstructive philosophies on the states. And, finally, when at last something was done, we were still left with three gauges, a dozen breaks of gauge — which, at one stage, included two three-gauge stations only a few kilometres apart — and a half-baked standard gauge system that one could be pardoned for suggesting had been designed specifically to ensure that complete unification could never be achieved.
 * ... Today, after more than 100 years of Federation, we are left with 33,500 route kilometres of public railways on the mainland, still of three gauges — 4000 broad, 15,100 standard, 14,100 narrow and 300 dual — together with ten operative breaks of gauge and three inactive ones on account of the cancellation of services.
 * That should demonstrate why the term "Australian gauge" doesn't have traction anywhere in Australia, and why it hasn't been used historically -- it simply wouldn't make sense. If used overseas it would be erroneous through being a meaningless term. It won't therefore be found in a published source. (I'm confident on this subject because I've been involved professionally with the Australian railway industry for a long time.)


 * So, unless you disagree, could you clarify what sort of citations you think are needed now? I'll try to help.


 * Cheers, Simon – SCHolar44 🇦🇺 💬 at 00:58, 24 February 2021 (UTC)
 * I see! As for, there is no use in adding any "Australian gauge" ID. It's as wide as "broad gauge" is: not specific. So, we'll remove Victorian (b/c unsourced), and not add anything. -DePiep (talk) 20:44, 3 March 2021 (UTC)

Comma off option
MOS:DIGITS says: "Numbers with exactly four digits left of the decimal point may optionally be grouped (either 1,250 or 1250), with consistency within any given article." Could Track gauge get a  option like Convert? PrimeHunter (talk) 22:04, 12 January 2021 (UTC)
 * Read, will dive into this. -DePiep (talk) 23:20, 12 January 2021 (UTC)
 * Could we have a space instead of the comma? Peter Horn User talk 00:52, 13 January 2021 (UTC)


 * PrimeHunter: MOS:DIGITS, in saying "Numbers with exactly four digits left of the decimal point may optionally be grouped (either 1,250 or 1250) ...", overlooks the formal SI preference for a space: "Spaces should be used as a thousands separator (1 000 000) in contrast to commas or periods (1,000,000 or 1.000.000) to reduce confusion resulting from the variation between these forms in different countries", and perhaps that's what Peter Horn had in mind (or maybe not) in asking for a space instead of the comma. My experience has been that the space is used much less often than when the SI convention was instigated -- it seems to me that people are now pretty well aware of the convention in the "other" jurisdiction.
 * In the event, provision could be made for three options: default comma, space, no comma until there are 5 or more numerals. ("Comma=5", as already provided in Template:Convert, is better than "comma=off", because once you get to millions the comma is inserted at position 3 in addition to position 6.)
 * DePiep, have you had time yet to dive into this? Cheers, Simon – SCHolar44 🇦🇺 💬 at 06:45, 19 February 2021 (UTC)
 * We should not support an option that is not supported by the MOS, regardless, which would appear to dis-include the ISO's preference. --Izno (talk) 07:15, 19 February 2021 (UTC)
 * Hmm. Given the eminence of the SI as a world authority, would it not be better to add to the MOS? SCHolar44 (talk) 07:31, 19 February 2021 (UTC)
 * If you believe SI having a specific preference is sufficient to see something added to the MOS, you will be quite surprised. Regardless, adding it to the MOS is blocking to adding it here. --Izno (talk) 08:04, 19 February 2021 (UTC)
 * Sorry, Izno, I don't understand "is blocking to adding it here" in your 2nd sentence. Could you please clarify? Thank you. Come to think of it, a bit of background about being surprised about adding to the MOS would also be appreciated -- I'm keen to benefit from your experience. SCHolar44 (talk) 08:11, 19 February 2021 (UTC)
 * "blocking" in a development process usually refers to "you need to sort the blocking thing out before doing the blocked thing". In context, adding to MoS is blocking adding it here means "you must have it added to MOS before adding it here".
 * As for surprise, the MOS is its own MoS. While we may take into consideration some particular style, we often need to make other concessions or actively reject other style points. For example, regarding the symbol of a byte or its multiples, I do not think we follow SI. (Why is left to the curious reader.) The case of a space separator is a case where I believe our desire to have a consistent numerical representation for both technical (for SI's primary concern is technical for the majority of its recommendations) and non-technical readers (the majority of ours are undoubtedly the latter) would likely have us reject a change to include spaces as a permissible 10^3n separator (and/or 10^-3n). But, if you should feel obliged on the point, start by reviewing the talk archives there (WT:MOSNUM) to ensure it has not been discussed, and then start a new discussion with your understanding of previous discussion laying out why you think the MOS should change. --Izno (talk) 08:25, 19 February 2021 (UTC)

Talk:3 ft 6 in gauge railways & 3 ft 6 in gauge railways , (4 ft 6 in gauge railway), (4 ft 6 in gauge railway) The "lk=on" should go directly to 4 ft 6 in gauge railway instead of to Toden Arakawa Line. Peter Horn User talk 00:10, 1 March 2021 (UTC)
 * Perhaps this will work. . But it does not. Peter Horn User talk 00:42, 1 March 2021 (UTC)
 * I agree with you. Toden Arakawa Line is merely one of the railways using 4'6" track gauge. Linking "1372mm" to "Arakawa Line" is just like linking a word "human" to "Chuck Norris". --侵入者ウィリアム (talk) 13:06, 1 March 2021 (UTC)

 * At the current version of this template,  and   both generate a link to 4 ft 6 in gauge railway.

 * Interesting note: The "Toden_Arakawa_Line" is linked because it is defined metric not ft/in, with source! So: for consistency :-). Here at, we adhere to defined tracks, even per unit (ft/in or metric). So this is why the 1372mm link is as it is.
 * The article should be moved to 4 ft 6 in and 1372 mm gauge railway (Seriously. Because the metric one is defined & sourced). -DePiep (talk) 21:14, 2 March 2021 (UTC)

 * OK. (sandbox was in use for this change). -DePiep (talk) 13:49, 6 March 2021 (UTC)

Today:
 * Conclusion
 * 1) Target wikilink for is 4 ft 6 in gauge railway (no redirect)  generic ✅
 * 2) Target wikilink for is Toden Arakawa Line (no redirect), specific
 * (Probably used because article says 'define in metric', initially. But we can not confirm such a source today.)
 * All in all, there is no sourcing article (found yet) to claim an "1372 mm gauge" article. So nor change existing ft/in article into "4 ft 6 in and 1372 mm gauge railway".

Tomorrow:
 * So, we will redirect to 4 ft 6 in gauge railway, as requested.

Ever:
 * I add: base of the is that it encourages sourced track gauges. That is: gauges that are sourced, including their unit. e.g., "metre gauge " was never defined or ordered in ft/in units :-)

Template-protected edit request on 2 August 2021
Seems to have been an error introduced in a change to the Toronto gauge entry.

Basically, when the article was moved from Toronto gauge to Toronto-gauge railways, the entry in the data here was changed such that (basically the on version) lists "Toronto-gauge railways" instead of what it should list, which is "Toronto gauge" (i.e. list the name of the gauge as the link text, not the name of the article it links to).

This can be seen in the second paragraph of this, where the sentence reads: The trains are powered by linear induction motors and operate on tracks, unlike the city's subway lines and the Toronto streetcar system, which use the unique.

You can see the usage expects the template to generate something like "standard gauge", not "standard-gauge railway". You can see how Toronto sticks out currently as wrong in the table of gauges, where all the other "Alt Name" entries are in the form "[location name] gauge" (e.g. "Ohio gauge", "Russian gauge") whereas Toronto's entry is "Toronto-gauge railways".

I I've fixed this in the sandbox here but to be honest I couldn't quite figure out how to test changes made to the sandbox version of /data.

Anyway, can someone either make the change as per the link I've provided or, if it's incorrect, fix it so that when allk is set to "on" for "Toronto", it lists "Toronto gauge" as the link text and not "Toronto-gauge railways"? Joeyconnick (talk) 19:10, 2 August 2021 (UTC)
 * Yes, looks like an issue. Will take a look at it. For now, I have paused the Edit Request to do the sandbox checks. -DePiep (talk) 21:13, 2 August 2021 (UTC)

650 mm
In List of secondary, industrial and Decauville railways in Argentina I found the following new track gauge:  Peter Horn User talk 06:23, 13 October 2021 (UTC)
 * My first impression is that "0.65 m" is a typo or a data mistake. Would be very peculiar if for this 32 km of rails rolling stock with such an unique gauge would have been created. -DePiep (talk) 15:26, 13 October 2021 (UTC)
 * Who knows. There was also 0.51 m which would make  510 mm. The previous one would be 650 mm Peter Horn User talk 17:13, 13 October 2021 (UTC) Peter Horn User talk 17:17, 13 October 2021 (UTC)
 * "Who knows" indeed. No source then. Not acceptable for the list. (btw how does "0.51 m" prove anything?) -DePiep (talk) 19:13, 13 October 2021 (UTC)
 * 0.51 m The same as the reference for all the gauges in the List of secondaryarticle.
 * Or look for Ledesma Mill Railway (Desvio Ingenio Ledesma)
 * I repeat: 0.65 m gauge very unlikely, as it would require unique rolling stock. Why plausible?
 * As for 0.51 m: please take a good check yourself. What would your assumption be? -DePiep (talk) 15:53, 14 October 2021 (UTC)
 * I have found both within the followin text using "ctrl f" together ("find"). Just try that. Peter Horn User talk 18:27, 14 October 2021 (UTC)
 * Mea culpa, that text yielded only 0.65 m. That leaves 0.51 m as an error on the previous revisions of the article Peter Horn User talk 18:50, 14 October 2021 (UTC)
 * Sorry, not is not "Ctrl f". When the reference opens, there are instructions in German to the left. There is a search window and to the right of that "Los gehts". That allows me to find 0.65 m gauge. Peter Horn User talk 19:17, 14 October 2021 (UTC)
 * PS, That search window is called in German "im Buch suchen". Peter Horn User talk 16:21, 15 October 2021 (UTC)
 * That source is not reliable for obvious reasons, as mentioned. No base to include these. -DePiep (talk) 17:25, 15 October 2021 (UTC)
 * The source is a US government department publication which has been used as a source for most of the railways mentioned in the article, there are for me "no obvious reasons" why it should be unreliable. As for "not plausible", a number streetcar systems in the US had unusual, if not unique, track gauges. To this day the Toronto Transit Commission is hobbled by the Toronto gauge Peter Horn User talk 18:13, 15 October 2021 (UTC)
 * The "author" is not disputed. I wrote that the unique gauge is probably a typo or data mistake, because it is not plausible that a 32-km track in Tucuman Argentine would order an worldwide unique rolling stock with that gauge. About the "0.51 m", I suggested you took a little reasonability-research. Well this is what I though you could have found in a whimp: 0.51 m is quite likely a regular "20-inch" gauge, rounded in metrification somewhere in the reporting route. (If not a rounding difference, then the same unlikeliness occurs: why order an unique gauge?).
 * Since this is a talkpage, I have some talking notes to make. First, all the links you added are all to a single source. Doubling a link does not add quality for the claim. Also, it would be helpful if you tried to grasp my remarks & questions, and then build unpon those. For now, it looks like if you missed most of my points. -DePiep (talk) 18:43, 15 October 2021 (UTC)
 * I left a note on the usertalk of the original contributor. As there is only a single solitary source, this is not a problem. The US government had its military reasons for making this a list. Peter Horn User talk 21:10, 15 October 2021 (UTC)

A question
, on one hand 2.5 in, 2.5 in on the other hand. Should the output of template:track gauge not match the output of template:Convert? Peter Horn User talk 23:39, 4 November 2021 (UTC)
 * The conversion is 2.5 in 2.5 in, 2.5 in 2.5 in Peter Horn User talk 05:19, 26 November 2021 (UTC)
 * I don't think we need to. is handling precision & uncertainty in the generic way, bases on common measurement & precision theories in science. It's about scientists expressing uncertainty in the measurement (with original unit); convert then should try to reproduce that uncertainty as good as possible (but not suggesting more precision than the source says).
 * Track gauges, OTOH, are a defined size (length), and by unit so (defined in a certain unit). The definition size itself does not imply uncertainty/precision. Because: it is defined, not measured. Possibly the definition has specifications on tolerance in RL constructing, all right. We don't know them, we don't need to report them: for these specifications, go to the definition page (say, ). On top of this, the defined precision (tolerance) varies: for a TGV the SG tolerance is much smaller than for an underused fright track. So far for the defined size in a unit.
 * Then, when we (enwiki) convert to a non-defined unit, we should not imply or suggest precision in the new value. does consistently:
 * In the conversion, round to nearest 1 mm or $1/2$ in. [1 mm, 1/32 in]
 * In practice, this conversion is hardcoded into . For the model gauges, those under 89 mm or $1/2$ in, this guideline is not applicable.
 * This looks like a most understandable representation, not-impractically precise and expressed in commonl;y recognisable units. -DePiep (talk) 09:14, 27 November 2021 (UTC)
 * Yeah, but we DO have, so what is the problem with  being more precise? Peter Horn User talk 00:08, 23 January 2022 (UTC)
