Talk:EMD GP40-based passenger locomotives

Context
I flagged this as needing context, since it never says what it's about. However, there are more than a dozen pages linking here, so this doesn't seem to be a nonsense article.

December 2009 tags
I tagged this article because, while I contains a treasure trove of information, it reads less like an encyclopedia article and more like a posting to a railfan message board.

Much of the detail, such as specific horn models or the long lists of locomotive numbers detailing the exact provenance of each unit,should go, as it is of little interest to a general audience, and Wikipedia is not a railfan's spotters guide

Truthfully, each section should probably be stripped down to answer three questions: Details beyond that, other than perhaps a distinguishing feature of that model, should be eliminated. After all, these locomotives are more alike than different, being based on a common platform, and widely adopted due to the commonality of that platform. This article should be a shorter, more basic overview of that, not the be-all-end-all guide it is trying to be. oknazevad (talk) 12:23, 1 December 2009 (UTC)
 * What agency(ies) used the model?
 * How many were built?
 * When were they (re)built, and by whom?
 * I have done a small amount of tidying-up but, because of my limited knowledge of these locomotives, I will leave the rest to others. Biscuittin (talk) 21:32, 9 January 2010 (UTC)
 * I decided to do a bit more and I've removed all the "Roster" sections to comply with the "excessive detail" tag. This might be controversial and, if somebody wants to revert it, I don't intend to start an edit war. Biscuittin (talk) 18:01, 10 January 2010 (UTC)

Citations issue
This article is a regular magnet for unsourced information and has entire sections which are unsourced. I think a tag at the top indicating a need for improved references is justifiable. Mackensen (talk) 15:18, 1 February 2019 (UTC)

F40PH
This article seems to be missing the most significant EMD GP40-based passenger locomotive, the F40PH and its derivatives—475 units built new by EMD dwarfs by far anything else on this list, and the original F40PH was just a GP40-2 with an HEP generator and a cowl. I'm curious if this is a conscious choice, since I think it would make the most sense to see a section on the F40PH or at least a reference to its own article. Thoughts?

 * I would say it's a conscious choice, inasmuch as the EMD GP40 and EMD GP40-2 are distinct designs. Mackensen (talk) 22:33, 22 September 2022 (UTC)

Interesting. The intent is that this article should be limited to GP40 only and not include the Dash 2 line? Every single one of the types listed on this page were upgraded to Dash 2 spec sometime in their lifetime (true of most freight GP40s also, if they lasted long enough), but more importantly a couple (at least GP40P-2 and GP40MC) were built as Dash 2 units at EMD originally.

For example, in 1988 Morrison-Knudsen rebuilt five GP40s into F40PHL-2 for Tri-Rail. This seems basically the same as the six GP40s they rebuilt into GP39H-2 for MARC a few years prior except that the Tri-Rail units got a new cowl and cab (and more horsepower.)

So at the very least this article needs to be more clear about what it’s including and what it isn’t. If its only pre-‘72 locomotives and rebuilds that keep the sheet metal intact, the intro should be more clear. Akosut (talk) 08:55, 26 September 2022 (UTC)


 * The point of this article is passenger variants of the hood-unit GP-40s, not the cowl-unit F40s, which, although mechanically based on the same technology (and sharing a large number of parts originally), is a separate model with its own article. A see also link is appropriate, but a section is out of scope. oknazevad (talk) 21:32, 15 May 2023 (UTC)

Unrebuilt GP40WH-2s
There needs to be a change done to this article, as there are some surviving unrebuilt GP40WH-2s currently owned by leasing firms (with one (PNLX 57) being spotted in Winter 2022 pulling Steam Railroading Institute's North Pole Express in Michigan. — Preceding unsigned comment added by 2600:4040:7836:9E00:B532:7F3D:D4F6:8363 (talk) 02:33, 23 May 2023 (UTC)
 * "I saw it one day" doesn't count as a source. If you don't have a reliable source for your claims, they will not be added to the article. We don't "need" to do anything just because you say you saw something. Trainsandotherthings (talk) 16:10, 23 May 2023 (UTC)

Semi-protected edit request on 25 October 2023
This page needs a TON of updating, especially with the GP40WH-2 section. The reason I state this is that the remaining GP40WH-2 units that have not been rebuilt for SunRail are in possession of leasing firms (for example: ex-MARC #57 is owned by PNLX ).
