Talk:Norwegian coupling

1870 or earlier?
Surely the Norwegian coupling was developed when Engineer Carl Pihl introduced the narrow gauge to reduce costs?

The Roros Railway opened in 1862, well before 1870. Tabletop (talk) 13:11, 30 August 2015 (UTC)
 * ... but it is not clear that Pihl suggested the coupling at the same time; it might have been introduced later. The only reference I found, in the Roell encyclopedia form 1912, unfortunately does not state a year. --User:Haraldmmueller 21:05, 12 April 2022 (UTC)

Origin of nickname
The article fails to explain the origin of the "meat chopper" nickname of this type of coupler. — Quicksilver (Hydrargyrum)T @ 21:22, 16 January 2017 (UTC)
 * The term "chopper coupling" seems to be more commonly used, but the origin can only be assumed. --188.174.111.149 (talk) 23:57, 14 May 2017 (UTC)

This really needs a picture

New Zealand
The article says:
 * "On railway lines where rolling stock always points the same way, the mechanical hook may be provided only on one end of each wagon. This was the situation... still applies to railways in New Zealand".

But there are wyes in New Zealand, so wagons could change their orientation. What's meant by the statement? --User:Haraldmmueller 20:52, 12 April 2022 (UTC)

Coupler, not coupling?
Are there strong reasons (possibly British terminology?) why "coupling" is used? Worldwide, "coupler" is more or less the standard terminology. See, for example, Janney coupler. Cheers, Simon – SCHolar44 🇦🇺 💬 at 03:15, 12 June 2023 (UTC)
