Proposed structure for this category[edit]

Currently, this category is a mess with inconsistent naming and subcategories at multiple and inconsistent levels. Accordingly, propose the following structure to sort it out:

General principals:

  • Categories should be named "locomotives" not "railway locomotives"
  • By country categories should be "of country" not "in country", or "adjective country", etc (e.g. "Narrow gauge locomotives of Australia" not "Narrow gauge locomotives in Australia" or "Australian narrow gauge locomotives")

Open questions:

Discussion[edit]

  • Comment:- whilst it may seem obvious that a locomotive runs on rails, there is such a thing as a road locomotive. This can be got around by stating the the scope of each category is for railway locomotives at the category's page. I see no harm in having a category for preserved locomotives. The Cape gauge / 1067mm gauge subcats are correct. The former being for locomotives in the south of Africa and the latter being for Japanese locomotives, Japan using metric to measure its 3' 6" gauge railways.

    So Category:Cape gauge railway locomotives should be a sub-category of Category:Narrow gauge locomotives of South Africa? Category:Locomotives is about railway rolling stock (although it doesn't explicitly state that) but I see no issue with confusion, especially as gauge isn't really a defining characteristic of road locomotives.

    Yes, because there were also 2-foot gauge railways in South Africa. Cape gauge is not exclusive to the country of South Africa though. It is used in much of southern Africa. Mjroots (talk) 20:02, 23 March 2021 (UTC)[reply]
    That sounds then like it should be a redirect to Category:3 ft 6 in gauge locomotives, with the SA locos being in Category:Category Cape gauge locomotives of South Africa with similar ones for other countries? Thryduulf (talk) 21:53, 23 March 2021 (UTC)[reply]
    I don't think we need to split Cape gauge locomotives by country. The current split of 3 ft 6 in gauge locomotives is good, and logical. Mjroots (talk) 08:01, 24 March 2021 (UTC)[reply]
  • From my comment at the TfD: don't think we need to have duplicate categories for different units of measurement. Some merges are obvious when there's a common name which does not involve a unit (Standard gauge, ...). Haven't looked up the rest. RandomCanadian (talk / contribs) 16:20, 24 March 2021 (UTC)[reply]
