Talk:Buffers and chain coupler

Alleged copy

This article (first version) is copied from Railway coupling. The site ( http://www.cs.mcgill.ca/~rwest/wikispeedia/wpcd/wp/c/Coupling_%2528railway%2529.htm ) which contains the same text, is copied from that Wikipedia article. Generally the site http://www.cs.mcgill.ca/~rwest/wikispeedia/wpcd/index.htm contains copies of Wikipedia, and it does not claim copyright on its text, and should not be assumed to in any case. So maybe the bot should exclude that site fromthe list of copyrighted encyclopedias. --BIL (talk) 08:16, 17 September 2013 (UTC)

No need for duplicate info

What's the use of having the same information in two articles?

BIL gave two reasons:

• The presence of many links to this subject: I can't imagine that there is an abundance of links pointing to a non existing page. If this would have been the case, this page only needs to be a redirect to Railway coupling.
• Where are the interwiki's you are mentioning?

There doesn't seem to be any justification to duplicate info that is nicely centered on one single page. --Aaron-Tripel (talk) 16:53, 17 September 2013 (UTC)

There are articles about almost every other type of coupling, but not about the European standard, which is odd. There are many links to Railway coupling#Buffers and chain. I shall add the interwiki links if we can agree to allow this article to exist. There are at least four other language articles about this coupling, e.g. de:Schraubenkupplung. I want to reduce the amount of text about this coupling in Railway coupling, and extend it here. --BIL (talk) 19:23, 17 September 2013 (UTC)

External links modified

Hello fellow Wikipedians,

I have just modified one external link on Buffers and chain coupler. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

• Added archive https://web.archive.org/web/20060926185507/http://www.wsr.org.uk/couplings.htm to http://www.wsr.org.uk/couplings.htm

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

Misrepresenting relative safety of buffer and chain coupling

Third paragraph on the page is completely dedicated to showing how "unsafe" buffer and chain coupling, presumably compared to North American Janney couplers, without citing any sources and significantly misrepresenting the coupling method. The paragraph claims that unlike Janney coupler buffer and chain coupling requires workers to get between the cars, implying that that is not the case with Janney coupler. This is not true, Janney couplers also require workers to get between the cars to make electrical and pneumatic connections between the cars (see for example .

Clarification

By way of clarification. Each wagon has a tow hook and a chain. Each chain has a turnbuckle between two, NOT three, elongated links. When coupling two wagons together the worker can put either chain into the tow hook of the other car. Peter Horn User talk 17:17, 27 September 2021 (UTC)

No. There were several forms of the coupler used in the UK. All of them had a drawhook (not a "tow hook") mounted on the bufferbeam, this hook has a hole between the hook proper and the mounting point, through which one link of the coupler is passed; this is a permanent attachment. The coupling itself has no hook. This is a drawhook with the coupling removed; the hole that it would pass through is clearly visible.

• The simplest, used on goods wagons without a continuous brake, had three plain links. The free end is placed over the drawhook of the adjacent wagon; the coupling attached to that wagon hangs free and is not used. This is a three-link coupling; you will see that the upper link passes through ths body of the drawhook, it is not placed in the hook itself.
• Second simplest is the "Instanter" coupling, which has two plain links with a special triangular link in the middle. The triangular link has two sides the same length as the plain links, whilst the third side is much shorter. When shunting, it is used in the same way as the plain three-link type; when the train is assembled and ready to start, the triangular links are turned so that the short side is uppermost, with both plain links in that end. This brings the buffers close together, and is suitable for goods trains with the continuous brake. This wagon has an Instanter coupling; the bottom plain link is hanging from the short side of the triangular link.
• The third kind is the screw coupling, where the central link is in the form of a screw shackle (n.b. not a turnbuckle). This is used on locomotives, passenger coaches and later types of continuously-braked goods wagon. Like the Instanter, it is extended when shunting, and drawn tight for the train to run. This is a screw-link coupling in the stowed position; this is one that is coupled and tightened up ready for the train to move.

I can see that I am going to have to thoroughly check the recent changes. --Redrose64 🌹 (talk) 09:48, 28 September 2021 (UTC)

@Redrose64: Then there are two types of chains. There is the plain three link chains without a turnbuckle and the more modern chains with a turnbuckle between two elongated links. In either type, or all types, the chain hangs from the drawhook. in either type, or all types, the chain of one car is put into the drawhook of the other car. In addition there are the type of chains you mentioned above. Can you find illustrations (images or files) of the ones you mentioned? Peter Horn User talk 19:28, 28 September 2021 (UTC)
