Talk:Washington Metro rolling stock

message: For the Rohrs, and the 2000 and 3000 Bredas, we need to separate out the facts/figures for these cars as originally delivered, vs. how they exist rehabilitated. I'll play with it some more when I get home, but I just thought I'd throw that one out there. I plan on doing some more reworking on the article when I get home as well.

thread_title: Rearrangement

message: I think it would be great to add some detail on what makes the particular braking sounds. It seems to be a hot topic on YouTube to speculate what makes the noise: http://www.youtube.com/watch?v=is5vzJPBksQ ("electrical reversal in which the motors are braking speed to stop the train"), http://www.youtube.com/watch?v=G6dc5JdMgd0 ("the sounds come from devices called GTO thyristors, which feed pulses (the gear changing sounds) of current to the traction motors") Bajenkins (talk) 04:00, 13 January 2008 (UTC)
replies: text: Well, the 3000 and 4000-Series Bredas get their distinctive buzz from an electronic "chopper", but as for the others, I couldn't tell you right offhand. Either way, though, I would think that descriptions of these sounds would be better placed in a different article than this one, perhaps one on AC motors? SchuminWeb (Talk) 05:37, 13 January 2008 (UTC)
replies: text: Some people think the motors are essentially being put into reverse to stop the train, some think they are being used in regenerative braking, and some think it's just normal motor noise. I don't see the harm in adding two or three sentences to the effect of 1) the buzzing is made by chopper-controlled DC motors in the unrehabbed 3k/4k series, and the whirring/whistling is caused by xxx in the AC motors. and 2) it's motor-reversal/regenerative/whatever braking. Moreover, I think it would be better to put the information in this article than as an aside in a AC/DC motor article. Bajenkins (talk) 22:02, 13 January 2008 (UTC)
replies: text: YouTube speculation is not a reliable source for inclusion in Wikipedia articles. If the mechanics behind Metrorail breaking sounds are documented by reliable sources, I'd favor their use in cited references with a related article. —Adavidb 01:06, 14 January 2008 (UTC)
replies: text: I'm certainly not suggesting YouTube speculation is a reliable source of information. It's just that I noticed the widely varying theories and came to Wikipedia looking for the correct answer. I was kind of amazed that it was not mentioned anywhere.

message: This question is mainly directed at Fan Railer, but if anyone knows: Where does it show that Alstom won the bid for the 7000's? From what I can tell, bids have been requested, but no winning bid has been named. SchuminWeb (Talk) 01:54, 26 February 2009 (UTC)
replies: text: my bad, i was suppose to delete the alsom thing, since i copied the datatable from the 6000 series section, but got caught up in putting new info on it that i forgot to delete it. according to the attatched document, we won't know the selected builder until the third quarter of this year, with the prototype cars arriving the second quarter of 2012.Fan Railer (talk) 03:01, 26 February 2009 (UTC)

message: I saw in the article that the 8000 series was going to be the replacement for some of the older stock.  Cited in a PDF from 2008.  I also found that the "money train" cars were renumber to the first four spots in the 8000 series.  I'd like to update that section and also include a section about the TGV or Pickle.  Do you think it should be in this article or in the main DC Metro article? Chuckbenson (talk) 17:43, 16 March 2016 (UTC)

thread_title:  Citation for number of 7000-series cars in service? 

message: Hello fellow Wikipedians! I'm not sure what the 1,138 number is in the lead: I tried to do some calculations and I think it used to be the total number not including newly-wrecked cars and the 7000-series. Should it be updated to reflect the cars which are currently in active service, or the number of cars ordered so far? Daybeers (talk) 18:42, 16 February 2018 (UTC)
replies: text: According to page 148, there are 1238 currently owned cars, and 1132 in service, as of November.--Kew Gardens 613 (talk) 19:00, 16 February 2018 (UTC)
