Talk:Pennsylvania Railroad class GG1

message: I felt that some mention should be made that famed industrial designer Raymond Loewy should be made, since he had a hand in "styling" the GG1. Tom 00:37, 19 January 2006 (UTC)

message: I read somewhere that the GG-1 used three-phase motors, therefore preventing the lack of starting torque associated with single-phase motors. That means somehow the alternate current was rectified and three phases were generated on board again. The problem is I can't find the source and I haven't found that information elsewhere. —The preceding unsigned comment was added by Canonicus (talk • contribs).
:The PRR used 25 Hz power partially so they could use ordinary series traction motors (running, essentially, as "universal" motors). I could be wrong, but I'd be surprised to hear that the GG1 used anything other than those.
:In the technical discussion, I recently added a reference and quote regarding the GG1's propulsion commutator design ac motors: that they are not brushless ac induction motors which have very poor starting characteristics. But so far I found nothing regarding speed control of these motors. One on line writer said that the locomotives carried a step down transformer and added that there are 22 steps on the engineer's throttle. But so far have found nothing that can be quoted and cited. This is an important part of the GG1 locmotive: starting heavy loads, then increasing speed through changes to the motor magnetic fields.

replies: text: In series wound AC motors the speed is proportional to the voltage applied, just like a DC motor.  (In an induction motor the speed is proportional to the frequency.)  On a straight AC locomotive the method to obtain different voltages was through transformer taps (resistance grids would have been wasteful since AC can be transformed).  A 22 position controller would have been sufficient for smooth acceleration.  There are photos of the controllers showing the number of notches and propulsion info is located in some books I don't have with me right now.  I can go look it up this weekend if you want.Sturmovik (talk) 12:11, 28 June 2018 (UTC)

message: This is an electric locomotive, but there is an old film on Youtube showing a GG1 being filled with fuel oil and water ().  Why would this be, if the locomotive is electric? -- Gyrofrog  (talk) 15:28, 10 April 2010 (UTC)
replies: text: Most likely for the onboard boilers used to supply heat to passenger cars. ​​​​​​​​Niagara ​​Don't give up the ship 15:40, 10 April 2010 (UTC)

message: Do we have more information about speed restrictions in the 1970s? This GAO report says (page 29) that they were limited to 85 MPH. Mackensen (talk) 13:58, 17 February 2017 (UTC)
replies: text: GG-1 speeds bounced around a bit and one would likely need to research Amtrak equipment speed lists in historic  Employee timetables. At some point a select number were re-geared by Amtrak in the late 70's for 110mph, but they started to have bearing overheating problems as a result and were bumped back down.  There is also the issue that half the fleet was owned by Conrail for freight service.  They were geared for 90 and Amtrak may have limited them to 85.Sturmovik (talk) 12:04, 28 June 2018 (UTC)
thread_title:  Amtrak-era speeds 

message: This museum is hardly about to publish the fact that it quietly donated that GG1 back to the Leatherstocking Museum on 1/27/22. Accordingly, I strongly recommend that you do one of two things if you keep rejecting my prior edits:
(1)Call the HFM at (313)982-6020 and ask for the appropriate Board member who was involved in the 1/27/22 donation back to Leatherstocking.
(2)Email my own source: . He personally owns the other GG1 at his museum (also bought in 1983), but did the 1/27/22 deal with HFM on 1/27/22, after several decades of giving HFM’s paid contractors access to it to remove asbestos and PCB’s; repair brakes on it for a move that will now never happen; et al.
If these primary sources are not enough for you as Wiki Guardian Angel of Purity, just forget it. I can hardly force HFB to issue a press release on what to then is a minor, $15,000 return donation from an ancient purchase of done three decades ago.

replies: text: If your source wants to jump on Twitter and make a post indicating the above, by all means go for it (and I do mean that seriously, we'd use a primary source from the Museum or the owner as verification). As mentioned in the main section, we can't just take the word of someone who says it's true because they spoke to someone else; it has to be verifiable somewhere. Hell, even if I were to email or call the Museum, I couldn't change the article because I cannot be the source. If something needs changing on Wikipedia, we need to be able to point to a website, publication, or other medium to say "yes, it happened". Primefac (talk) 22:56, 7 February 2022 (UTC)
thread_title:  Henry Ford Museum action 

message: On Monday AM, I will call the Chief Curator at the Henry Ford Museum: Matt Anderson. If he is not in, I will try for the Curator of Transportation: Marc Greuther. Either way, I will ask one or both of them to edit the Wiki GG1 article to remove the parenthetical text on “(purchased by the Henry Ford Museum)” under locomotive #4909. Will this satisfy your “rule book”? Please reply ASAP. Thank you. -DLP- 2600:1004:B114:5E9B:7581:95A1:A10C:A8F7 (talk) 03:05, 13 February 2022 (UTC)
replies: text: Pretty sure the answer to that is no. It needs a source. The museum can put out a source or press release stating so. Getting people who agree with you to edit WP articles could be considered meatpuppetry wizzito | say hello! 03:19, 13 February 2022 (UTC)
replies: text: I agree with Wizzito. If you're going to call them, tell them to make a post somewhere (social media, official publication, whatever). Just as you or I cannot change the information without a published source, neither can the Chief Curator of the museum (for all of the reasons previously stated in the other threads).
