Archiving

If there are no objections, I am going to archive all talk on this page older than 30 days. The V-Man ^{(Said · Done)} 06:58, 9 September 2009 (UTC)[reply]

Faulty source

Footnote 12 (Welovedc.com) is a blog, and thus violates WP:SPS. We should try to replace it with something that meets WP:RS. - Biruitorul ^Talk 04:35, 10 September 2009 (UTC)[reply]

In all cases, it's used as a secondary source. I have removed it. The V-Man ^{(Said · Done)} 13:11, 10 September 2009 (UTC)[reply]

Great! Thank you. - Biruitorul ^Talk 20:47, 10 September 2009 (UTC)[reply]

FAC withdrawn

This article was brought to FAC prematurely; I have removed it. To any potential nominators: Please make sure to consult the article's main editors before performing any such nomination, in addition to carefully reviewing the Featured Article criteria at WP:WIAFA. --Andy Walsh (talk) 02:21, 5 February 2010 (UTC)[reply]

NTSB released a lot of documents that we should mine for this article

Here it is:

http://www.ntsb.gov/Dockets/RailRoad/DCA09MR007/default.htm

This is like a treasure trove of information right here, and a lot of this might be useful... SchuminWeb (Talk) 13:21, 17 July 2010 (UTC)[reply]

Pay particular attention to the interviews with road foremen and track workers. The workers say that the equipment in the cabinet and the equipment on the track bed were mismatched and caused trains to "disappear" or "phantom" trains to appear, or simply repeatedly "bob" from danger to clear. This signalling equipment provides information to the train control systems. Since the early 2000s there has been an ongoing project to replace all signalling equipment since it was found to be failing decades earlier than its design life. To reduce the amount of scheduled track out of service, the signalling equipment in the cabinet was replaced first and, at a later date, the equipment on the track bed was replaced. Sometimes this happens in the opposite order. In the meantime, the mismatched equipment (from different manufacturers) had a tendency to "bob." I have not seen the mismatched equipment issue get any attention from the press. --KJRehberg (talk) 19:25, 9 July 2014 (UTC)[reply]

Cause

It says under investigation but History Channel just said it was the bad relays that made the stopped train invisible. Daniel Christensen (talk) 00:34, 6 January 2011 (UTC)[reply]

More specifically Engineering Disasters on Modern Marvels. Daniel Christensen (talk) 00:50, 6 January 2011 (UTC)[reply]

Updates

This event took place 5 years ago, but most of the information from the final NTSB report has not yet been incorporated into the article. I'll give a go at cleaning it up. Does it make sense to reduce the size of the initial investigation section after the final report has been issued? Not sure how much relevance there is to hypotheses in the immediate aftermath. 216.164.56.98 (talk) 20:08, 28 June 2014 (UTC)[reply]

Added some basics. Next is to summarize causes and recommendations in the NTSB report and trim down the "initial inquiry" sections. 216.164.56.98 (talk) 20:48, 28 June 2014 (UTC)[reply]

Kindly see my comments above concerning the interviews claiming mismatched signalling equipment that the press has not seemed to notice. --KJRehberg (talk) 19:28, 9 July 2014 (UTC)[reply]

MOS:DATECOMMA in "see also" link

I agree that, if we were talking about the Washington Metro train collision that occurred on November 29, 2009, in a sentence, a comma would be necessary after the year per MOS:DATECOMMA.

I do not agree that in a non-sentence, such as an article title or "see also" link, that comma after the year is necessary. MOS:DATECOMMA only addresses complete sentences, not titles.

But I don't have the time or wherewithal to debate this with someone who firmly feels to the contrary. I'm obsessive about punctuation, too, but I have too much else to do to get into this battle. - Julietdeltalima (talk) 18:57, 22 June 2022 (UTC)[reply]
