No details about FL9AC rebuilds?

[edit]

I don't have any authoritative sources to go by, otherwise I'd add a section myself. I myself have only bare details, e.g. the rebuild thereof was by ABB Traction, the locomotive horsepower was increased per unit to 3000, DC traction motors were replaced by AC traction motors, they could run in electric mode at GCT as opposed to having the prime mover running and belching diesel exhaust at the platforms there, one unit could haul a train versus two, and that's about it.

current status

[edit]

My understanding was that the Metro North replaced them all with the dual-mode GE Genesis units, but I wouldn't trust that without corroborating evidence. Ckape 04:24, 6 Jan 2005 (UTC)

Most recent info I could find was that they were being replaced by the Genesis on most services, but a few were being retained for short local runs and as backup. This was circa 2002, so there has been a little while since then ... —Morven 08:18, Jan 6, 2005 (UTC)
Well, I've done a little more research and it sounds a bit like they're being phased out, but the process isn't complete yet. It also looks like the best bet to take pictures is to find the Croton-Harmon shops. I understand they have annual open-houses there, but it looks like they're always in mid-October. -- ckape (talk) 23:23, 10 Jan 2005 (UTC)

The FL9s are no longer used in passenger service. The word from Metro-North is that they'll be around for use on work trains until they break down, at which point they won't be fixed. Pgengler 15:34, 31 October 2005 (UTC)Reply
They are still in service. Revenue service has decreased due to leased P40s but some runs, especially the Waterbury branch, still use them. —Preceding unsigned comment added by 70.23.5.126 (talk) 22:22, 3 June 2008 (UTC)Reply

The article may be badly screwed up ... I will have to contact a friend in Pittsburgh who goes back further than I but I believe the the (Metro North only ?) FL9s were diesel only (with the diesel supplying the DC power to run the motors). I believe that the third rail capability and AC motors were added with the FL9-AC Dual Mode rebuild by ABB Traction Inc.; ten locomotives were re-designed / re-built starting in late '80s / early 90's with the last delivery in 1995 or 1996. They were in use until shortly after the 21st century began; after the GE Genesis locomotives had been introduced and debugged. Coming on board in 1992 as one of the electrical engineers on the project, I have fond memories of test runs up to Poughkeepsie and back (to the Croton-Harmon yard). It really is something to walk through the loco with the diesel running at full tilt. And looking out the window from the train engineer's station you feel like you're hardly moving even as the speedometer reads 90 MPH! The good old days! JimScott (talk) 07:13, 8 December 2013 (UTC)Reply

Another very old talk page comment I'm replying to here, but the FL9s were dual mode capable as built. The FL9AC rebuilds were largely a failure and were taken out of service pretty quickly. Metro-North's FL9s were diesel only towards the end of their lives due to their age, the electrical equipment was still there but didn't function properly and the FL9s ran into Grand Central with the diesel engines on in flagrant violation of the ban on non-electric locomotives operating in the GCT tunnels. That's called out in some of the sources I reviewed but I need to add it to the prose still. Trainsandotherthings (talk) 16:50, 26 December 2025 (UTC)Reply

Copy edit tag

I've added headings and I think the article is OK. May I remove the tag? If not, please say what further work is needed. Biscuittin (talk) 22:49, 11 December 2007 (UTC)Reply

FG9

[edit]

Discussion on LocoNotes about a heavy fuel B-A1A EMD locomotive called the "FG9". It was never built. Don Strack started the topic as he has correspondence between EMD and Union Pacific Superintendent of Motive Power Mr. Neuhart. --SSW9389 20:27, 4 May 2009 (UTC)--SSW9389 20:27, 4 May 2009 (UTC) —Preceding unsigned comment added by SSW9389 (talk • contribs)

Corrections

[edit]

Weight limit was for the Harlem River Bridge, not the entire Park Avenue viaduct; the three-axle rear truck reduced "axle loading" to fall within the bridge limit.

3rd rail has been extended from Woodlawn to Pelham, about 2½ miles. This allows changeover (DC to AC & vice versa) to occur away from the NH-Harlem interlockings at Woodlawn. Keo (talk) 22:41, 20 October 2011 (UTC)Reply

Yes, correct. They had to remedy the weight of the steam boiler (used for carriage heating). 82.134.208.198 (talk) 23:44, 31 May 2025 (UTC)Reply
This is a very old talk page comment, but I did want to say that during my rewrite and expansion all the sources I found explicitly called out the Park Avenue Viaduct as being the reason for weight restrictions. This was a consistent theme across sources from different authors and publications. Therefore, the article currently states that Park Avenue Viaduct was the reason for the A1A rear truck. Trainsandotherthings (talk) 16:46, 26 December 2025 (UTC)Reply

Third rail voltage

[edit]

I see the article currently claims a 660V DC voltage. Diesel Locomotives of the New Haven Railroad supports 600V DC, which is what I thought the voltage was. New Haven Line lists the voltage as 750V DC. Has the voltage changed multiple times? I'm going to change this article to reflect 600V DC unless I can find evidence to the contrary.

Article status

[edit]

I have a bit more work to do, but I've done a comprehensive rewrite and expansion of the article. All those orange banners are gone, and almost everything is cited now. There are a few issues that I haven't been able to fully address and remain obstacles to bringing the article to GA status:

  • I am having trouble effectively sourcing the subsequent history of the six Amtrak units retired in the 1990s.
  • I can't find a source for the claim that the FL9 purchased from CTDOT by Boston Surface has been purchased by Mass Coastal / Cape Cod Central.
  • I haven't been able to source the claim about the Merchants Limited travel time in the operation section.
  • For some reason, all references to FL9 2002 seem to have been removed from the RMNE website, though as far as I can tell it's still at the museum. There's an archived link from an earlier version of their website supporting that it is there in storage.
  • I'm not sure the "in popular culture" section should be kept, though it definitely needs a better source than IMDb. One of the sources I reviewed while doing the expansion did source that claim, so I need to track that down and add a citation.
  • I've added some detail on the FL9AC rebuilds and how they weren't successful, but I haven't found as much detail on why the rebuilds failed as I would have liked.

I'd appreciate any help anyone can provide with these remaining items. I was able to address the vast majority of the problems that existed in this article for many years, I just need a little help getting from 95% to 100% of the way to being ready for GAN.

I'll take this review. The usual boilerplate: please respond to comments with {{done}}, {{not done}}, etc. Note that I may make some suggestions that are beyond the GA criteria – my aim is to make the article as good as possible – but I will only pass/fail based on the criteria. Pi.1415926535 (talk) 21:52, 3 February 2026 (UTC)Reply

@Trainsandotherthings: Good work here, including your changes so far. Don't be discouraged by the number of comments below - most are minor fixes or cleaning up cruft that predates you. Pi.1415926535 (talk) 06:38, 6 February 2026 (UTC)Reply
@Trainsandotherthings: Placing on hold for now - just give me a ping when you're able to address the last few comments (or if you're busy IRL and need more time). Best, Pi.1415926535 (talk) 20:10, 10 February 2026 (UTC)Reply
@Pi.1415926535: Could I get your feedback on my responses to your items? Particularly the surviving examples section. Trainsandotherthings (talk) 16:45, 15 February 2026 (UTC)Reply
@Trainsandotherthings: My replies are below. The only remaining items I see are two splits of long paragraphs (just added these below), one item in the surviving examples section, and maybe that one paragraph merge. Otherwise, everything looks great. Pi.1415926535 (talk) 10:13, 16 February 2026 (UTC)Reply

Infobox and lead

[edit]
  • Infobox image is "near" Enfield per the source, not necessarily at Enfield station
    I assumed it was linking to the town of Enfield, rather than the station. I changed the link to point to the town. Trainsandotherthings (talk) 23:44, 4 February 2026 (UTC)Reply
  • Link "electro-diesel"
    Assuming you meant in the infobox, done. Trainsandotherthings (talk) 23:44, 4 February 2026 (UTC)Reply
  • Some of the infobox information is not sourced
    Removed roots blower as I can't find support for it, but Diesels to Park Avenue calls out the generators, traction motors, and air brakes. Did I miss citations for any other technical information? Trainsandotherthings (talk) 23:44, 4 February 2026 (UTC)Reply
  • I don't think we need to list the New Haven's designation in the lead; it doesn't seem to have been widely used.
    Moved the detail to the body. If I can remember how to do explanatory notes, I can put the information in one to further condense the prose. Trainsandotherthings (talk) 23:44, 4 February 2026 (UTC)Reply
  • I'd move the Foster cite out of the lead - it'd be odd to have it be the only cite there
    You're right, I missed that it hadn't been removed. Done. Trainsandotherthings (talk) 23:44, 4 February 2026 (UTC)Reply
  • Change the end of the final sentence to ; several remain in operation. (since the current wording makes it sound like the private owners are in operation, not the locomotives)
    Good catch, changed. Trainsandotherthings (talk) 23:44, 4 February 2026 (UTC)Reply

  • The list is partially 2015 status, partially current status. Either have it be current status only, or have it be 2015 status with subsequent history as relevant (my preference). There's also a bit of cruft to trim. I may have follow-up suggestions after this is done.
    The Classic Trains source specifies 22 surviving units but does not detail all of their numbers or locations. I've done the best I can with available sources. Will work on reorganizing, but I could use suggestions. Trainsandotherthings (talk) 15:38, 7 February 2026 (UTC)Reply
    Definitely a lot better now. Having acquisition dates for the units that currently don't have them would be nice, but the section is fine for GA as is.
  • Reduce this section to two images - I recommend the Danbury museum shot plus perhaps this shot.
    Cut some images, thinking about which ones I want to have in this section ultimately. Trainsandotherthings (talk) 01:17, 7 February 2026 (UTC)Reply
  • Too much detail about #2019. We don't need to know the one-week use or the train name.
    Cut some of the detail. Trainsandotherthings (talk) 15:38, 7 February 2026 (UTC)Reply
  • Have the two RMNE entries be sub-bullets of a single bullet
    Done. There were three FL9s at the museum at one point, but it looks like one has since gone to Ohio. I can't find any reliable sources on its current whereabouts or the fact that it left the RMNE (beyond it no longer being on the RMNE website). Trainsandotherthings (talk) 17:36, 16 February 2026 (UTC)Reply
  • Don't say "currently". Several items need as-of dates (or acquisition dates etc)
    •  Done
[edit]

I would remove this section. The Superman item is USERGENERATED trivia, and having models available is so common that I don't think it needs noted.

  • I'm not generally a fan of "in popular culture" sections, but I do have an interesting bit in Diesels to Park Avenue where Class of '44 featured a Canadian National FP7 with its nose dressed in a knock-off New Haven scheme looking extremely similar to an FL9. Not sure that merits mention in this article though. On the other hand, I think mentioning the models is relevant. Rapido is the only manufacturer to tackle the FL9, and I did include models when I wrote GE 25-ton switcher. The section likely needs removal, and the brief mention of the Rapido models could be placed elsewhere in the article. Trainsandotherthings (talk) 15:38, 7 February 2026 (UTC)Reply
    I've deleted the mention of the movie and moved the sentence about models elsewhere in the body for now. Trainsandotherthings (talk) 19:42, 7 February 2026 (UTC)Reply

  • I don't see what the GMD list or the British Rail locomotive have to do with this article.
    Seems they have the same arrangement of trucks and axles, but I don't think that's particularly relevant especially since the FL9 has an unpowered axle and that British Rail locomotive has all powered axles. Removed it from the see also. Trainsandotherthings (talk) 23:12, 6 February 2026 (UTC)Reply
  • Remove P32, as it's already linked in the article.
    I actually added that back in 2021 when it wasn't mentioned in the article. Removed. Trainsandotherthings (talk) 23:12, 6 February 2026 (UTC)Reply
  • Might be worth linking to the DM30AC in the article (when the failed FL9AC rebuilds are discussed), in which case this section could be done away with entirely. (The EMD list isn't worth having a section all to itself.)
    I have an issue here where sources disagree. The Classic Trains Magazine article dismisses the FL9AC rebuilds as a failure, while Diesels to Park Avenue calls them a success (on LIRR at least) and a direct inspiration for the DM30AC order (they just write "the order of dual-mode locomotives from General Motors which are due in 1998" but it's obvious what they are referring to). That source also mentions that gaps in the third rail would cause the onboard computer systems to shut off and then restart. Working on how to incorporate the DM30AC into the prose. Trainsandotherthings (talk) 23:12, 6 February 2026 (UTC)Reply
    Now resolved. Turns out the DM30AC is explicitly mentioned a few pages later. I've deleted the see also section. Trainsandotherthings (talk) 19:42, 7 February 2026 (UTC)Reply
