I'll get to this in the next few days. Ealdgyth (talk) 16:57, 30 January 2023 (UTC)

Hi @Ealdgyth:, as it's been a week could you let me know when you'll be able to review this? Trainsandotherthings (talk) 14:14, 6 February 2023 (UTC)

Tonight or tomorrow... husband was unexpectedly home for five days ... so I'm a bit behind. Ealdgyth (talk) 16:56, 6 February 2023 (UTC)

Okay, of course real life comes first, no worries. Trainsandotherthings (talk) 17:18, 6 February 2023 (UTC)

GA review (see here for what the criteria are, and here for what they are not)

1. It is reasonably well written.

   a (prose, spelling, and grammar): b (MoS for lead, layout, word choice, fiction, and lists):

2. It is factually accurate and verifiable.

   a (reference section): b (citations to reliable sources): c (OR): d (copyvio and plagiarism):

3. It is broad in its coverage.

   a (major aspects): b (focused):

4. It follows the neutral point of view policy.

   Fair representation without bias:

5. It is stable.

   No edit wars, etc.:

6. It is illustrated by images and other media, where possible and appropriate.

   a (images are tagged and non-free content have non-free use rationales): b (appropriate use with suitable captions):

7. Overall:

   Pass/Fail:

• Spot-checks:
  • "In a cow-calf set, the cow referred to the locomotive equipped with a cab, while calves lacked a cab. Cow-calf sets with two calves are known as "herds"; the only example of these were two TR3 series sets ordered by the Chesapeake and Ohio Railway." is sourced to this source on page 23 which supports part of the second sentence - "the only example of these were two TR3 series sets", but the source does not mention the Chesapeake and Ohio railway nor does it support the first sentence at all.
    • The cow having a cab and the calf lacking one is supported by page 10 of Foster, which I have added as a footnote. Marre supports the two three-unit sets being purchased by the C&O, and I have added it as a second footnote for the second sentence. Trainsandotherthings (talk) 16:41, 7 February 2023 (UTC)
  • "The cow, calf, and herd designations were nicknames and not official." is sourced to this source pp. 33-36 which supports the "The cow, calf, and herd designations were nicknames" part but not strictly speaking the "not official part"
    • I think this is really semantics, as by definition a nickname is not official, but I removed "and not official" just the same. Trainsandotherthings (talk) 16:41, 7 February 2023 (UTC)
  • "Most American examples were replaced by road switcher locomotives, which could both handle switching duties and haul mainline trains." is sourced to this source p. 10 which supports the first phrase "Most American examples were replaced by road switcher locomotives" but the second part isn't supported on this page.
    • The second part is a brief definition of what a road switcher is. I just removed it, I guess readers can click the link if they want to know what a road switcher is. Trainsandotherthings (talk) 16:41, 7 February 2023 (UTC)
• I randomly googled three phrases and only turned up Wikipedia mirrors. Earwig's tool shows no sign of copyright violation.

Let's get these taken care of before I go on to the prose/etc review. When these are dealt with, I'll do another quick spot check. I don't think it's a willful thing - just a bit of stuff getting moved from citations that previously supported it. Shouldn't be a big deal to fix. Ealdgyth (talk) 15:59, 7 February 2023 (UTC)

Looks good - I am filling troughs at the moment, but I'll do a quick check when I'm done and get on to the rest of the review in an hour or so at most.... I don't anticipate many issues... Ealdgyth (talk) 16:44, 7 February 2023 (UTC)

• Last spot check:
  • "The Union Pacific Railroad made use of cow-calf sets as helpers on a steep grade near Kelso, California, until 1959, when the use of multiple-unit train control made them obsolete." is sourced to this source which supports the information.
• Lead:
  • "and are connected with MU cables and brake lines" you've linked to "MU" but suggest a change to "MU cables" as the link set and perhaps a short explanation for the non-specialist?
    • I simplified this by rewriting as "The two are coupled together (either with regular couplers or a semi-permanent drawbar) and equipped with multiple unit train control so that both locomotives can be operated from the single cab." Let me know if you have further suggestions; as someone who's been train obsessed since I was a kid this can be a blind spot for me. Trainsandotherthings (talk) 18:19, 7 February 2023 (UTC)
  • "Cows are analogous to A units and calves to B unit road locomotives. Both have prime movers." No clue what this is supposed to mean? Suggest some sort of short explanation and a link for "prime mover" with an explanation?
    • I rewrote the first sentence as "Cows are analogous to A units (locomotives with a cab) and calves to B unit (powered locomotives without a cab) road locomotives." A prime mover is terminology for the engine(s) in a locomotive. I rewrote the second sentence as "The cow and calf are both equipped with prime movers for propulsion." but am not opposed to simply saying that both are equipped with engines. Trainsandotherthings (talk) 18:19, 7 February 2023 (UTC)
  • consistency - first paragraph has "A cow is equipped" but here in the second paragraph we have "the Cow-calf sets" and "with the Cow (or cabled unit)"? Either capitalize or decapitalize consistently.
    • I missed that when I rewrote much of the article... the lead was the part I changed the least. Cow-calf is not a proper noun and should not be capitalized, and I have made this consistent throughout the article. Trainsandotherthings (talk) 18:19, 7 February 2023 (UTC)
  • Per MOS:LEAD, information in the lead should be present in the article body - but "The two are coupled together (either with regular couplers or a semi-permanent drawbar) and are connected with MU cables and brake lines so that both locomotive units can be operated from the single cab." is not in the article body.
    • I've rewritten the offending sentence and simplified it, and tried to make sure it matches what's in the body. Trainsandotherthings (talk) 18:19, 7 February 2023 (UTC)
• Distinctions:
  • Can we get a quick explanation here for the technical terms "slugs" and "B units" in "Cow-calf sets are similar to slugs and especially B units."?
    • I've added more information, let me know if it's still unclear. Trainsandotherthings (talk) 18:19, 7 February 2023 (UTC)

I've put the article on hold for seven days to allow folks to address the issues I've brought up. Feel free to contact me on my talk page, or here with any concerns, and let me know one of those places when the issues have been addressed. If I may suggest that you strike out, check mark, or otherwise mark the items I've detailed, that will make it possible for me to see what's been addressed, and you can keep track of what's been done and what still needs to be worked on.

Changes look good, passing this now. Ealdgyth (talk) 19:45, 7 February 2023 (UTC)
