Many of the links in this article were as hilarious as they are useless. I have only partially finished correcting them. Peter Horn 00:45, 23 May 2009 (UTC)

Railway coupling by country. This info is all available from the latest, or any, edition of Jane's World Railways. Peter Horn User talk 03:10, 15 January 2012 (UTC)

Group by continents, and country groups
which would make it possible to see interoperability between neighboring countries. For example, within Europe and within the SADC (Southern Africa). --L.Willms (talk) 04:49, 9 August 2012 (UTC)

While different Scharfenburg couplers may be mechanically compatible, they may be electrically incompatible. Tabletop (talk) 13:15, 8 May 2013 (UTC)

Rail gauge 1065 mm
The article now writes, for Algeria:
 * "English couplers on gauge track" with as source Jane's.

It is the only mentioning of a 1065 mm gauge definition (see below, in Cape gauge/South Africa). I have no access to Jane's. I doubt whether the source really mentions this unique 1065 mm. This is what other sources say:
 * From National Company for Rail Transport (Algeria railways): ~1000 km of : CIA The World Factbook World factbook,
 * SNTF company website gives no clue
 * "A narrow gauge 1055mm gauge (same as the British forty-two inch gauge)" with printed sources mentioned
 * Looks like 1055 mm is more to the truth, and the Jane's citation may be a mistake.
 * This gauge was added to {RailGauge} in July 2013: RG Archive 3 for being in our page Cape gauge (now Three foot six inch gauge railways). That Cape gauge page has printed sources. All related pages state that "1065 mm" is the metric, rounded size for 42 inch.
 * All together, I suppose that "1065 mm" is not a new gauge definition (unless single source Jane's proves different). Next question: are "1055mm" and "1067mm" (42 inch) the same gauges, only differing $1/2$ inch (~12mm)?

 * 1055mm is a typical French application, only found in Algeria. (See also the odd 1050mm gauge of the Hejaz Railway. The reason for this kind of deviations of metre (or 3ft6in) has been puzzling me for a long time. I know for sure that 1050, 1055 and 1065/1067 are historically not the same, but there is a lack of supporting or explaining the differences.--Aaron-Tripel (talk) 14:40, 8 May 2014 (UTC)
 * Yeah, 5mm or even 12mm looks like serious to me, even in a less-precise era.
 * Shall we cut it short and declare this one to be 1055mm? Following the Algerian narrow gauge; accessed source the CIA fact book & more. If the whole 1055mm definition needs a change at WP, that is a different topic. -DePiep (talk) 14:50, 8 May 2014 (UTC)
 * Done--Aaron-Tripel (talk) 14:54, 8 May 2014 (UTC)

One: 5 mm can be serous. Two: the play between flange and gaugecorner can be big or small, in Russia where the gauge is 5 feet they have narrowed the gauge by 4 mm, also france have officially narrowed the play. three: You have to look at the specification to se if gauges that are within 15 mm are the same with different number. (Example: Spain have wery small difference in gauge BUT the wagons do not run well on the other railway, you can run them but with problem and usually reduced speed. It surprised me when I learned about that. There have been discussions to adjust the systems to a common standard but it has been scrapped since the change will be too costly.)Seniorsag (talk) 15:40, 30 October 2016 (UTC)

Pin and buffer
@User:ArnoldReinhold what is a pin and buffer or a pin and buffer coupler? Please explain and givthe source. Peter Horn User talk 03:20, 4 October 2022 (UTC)
 * @User talk:Peter Horn Here is a source: File:08-130 Esclusas de Miraflores (23).jpg. I'll add it to the article. Do you have a better description?--agr (talk) 15:13, 4 October 2022 (UTC)
 * @User:ArnoldReinhold The buffers have nothing to do with the coupler itself which resembles a primitive link and pin coupler but without a link. Thanks for the file, I noww have to revise the descripyion of the so called third rail. Peter Horn User talk 16:22, 4 October 2022 (UTC)
 * PS, I have added that file in Panama Canal locks Peter Horn User talk 17:50, 4 October 2022 (UTC)

@User talk:Peter Horn I looked through the relevant categories in Commons for any images of what might be coupled to the mules. Disabled mules are an obvious possibility. The only other thing I found was File:From Ship - panoramio - ---=XEON=--- (3).jpg which shows a rail crane with the same coupling. I scanned the Miraflores locks with Google Earth and found several cranes, but nothing else that might be coupled. File:Panama and the canal in picture and prose (1913) (14596913228).jpg shows what appears to be the same type coupling on a locomotive in 1913, suggesting it has been used since the beginning of the American canal effort. Back then mules might have had more of a utility role. BTW the central section of the Miraflores locks has interesting turntables at each end.--agr (talk) 14:40, 12 October 2022 (UTC)


 * @User:ArnoldReinhold Panama Canal locks mentions 4 pairs of mules handlinng large ships. The pairs are coupled together. Peter Horn User talk 17:12, 13 October 2022 (UTC)
 * @User:ArnoldReinhold I suggest a new catagory link, pin and buffer coupler Peter Horn User talk 17:35, 13 October 2022 (UTC)

A suggested split
I suggest this aricla be split in two. On one hand Europe, Asia and Ociania. On the other hand the Ameraicas and the Caribian. Peter Horn User talk 01:42, 10 October 2022 (UTC) Peter Horn User talk 00:27, 11 October 2022 (UTC)
