			TGV the train brand is changing its name to '''inOui'''. This article seems to be about the TGV train system and the TGV train brand.

	:: It explains a quarter of the increase ... 1M passengers/month times 6 months only equals 6 million passengers, while certainly respectable it still leaves 17M passengers unaccounted for, an increase which still is 4 times larger than previous years. Of course it can be correct because the TGV system is very popular but I think that number deserves a comment as to why the increase was so high for 2007. ] (]) 09:04, 23 August 2010 (UTC)
	:::You are right, the number is a misinterpretation of the source: the 128 million number includes non-TGV long-distance services. I'll remove it. --] (]) 16:54, 21 October 2010 (UTC)

	== Suggestion: clarify what 'LGV' is ==

	As a reader, I came here from the ] page where the term LGV is used without explanation.

	In this article, I first see the term LGV used near the end of the Development section, with no explanation or link. It is then used extensively throughout the article. I think this article could be improved by explaining the term, and/or linking to a page elsewhere on Misplaced Pages where it is explained. ] (]) 23:27, 8 December 2010 (UTC)



	The above question brings up a problem in the opening paragraph of the ] article. The article confuses and fails to distinguish between three different things:

	(1) 'TGV' which stands for ''Train à Grande Vitesse'' which means 'High Speed Train' in French, referring to a physical train;

	(2) 'LGV' which stands for ''Ligne à Grande Vitesse'' which means 'High Speed Line' in French, referring to a rail line designed for high speed (the principal characteristic of such a line is curves of very large radius);

	(3) Services operated by high speed trains. In France such services often have 'Brand Names' such as ] which is the name of the service of high speed trains between Paris and Brussels in Belgium, Amsterdam in Holland, and Cologne (Koln) in Germany.

	As examples:

	(1) ] and ] are examples of high speed TGV trains;

	(2) ] and ] are examples of high speed lines;

	(3) ] and ] are examples of high speed TGV services.

	Now, it is true that 'TGV' is also used informally in France as a name for the domestic French TGV services. But properly speaking this is a loose term (''la service TGV.....'').

	To answer Benthatsme's question, the ] article should spell out what the initials 'LGV' and 'TGV' stand for (I have done so above), and the opening paragraph should make clear the distinction between the services and the different types of TGV rolling-stock.

	I won't attempt to do this myself, but perhaps someone might attempt to make the article clearer.....

	== long tons, short tons, stones, and furlongs per fortnight ==

	Why does an otherwise acceptable article have to be polluted with a bunch of unit conversions? The trains were all designed and operated in SI, so those are the only units we should see.
	] (]) 08:38, 24 July 2011 (UTC)
	:I don't see those units used anywhere in the article ("ton" does appear twice, but it is unfortunately not clear whether or not those are meant to be ]). If you are instead referring to the somewhat more common units of feet and miles per hour, then their usage is recommended by Misplaced Pages's ], particularly the section regarding ]. Regards, <span style="font-variant:small-caps">]</span> (]) 17:47, 24 July 2011 (UTC)

	== Chinese trains, speed restrictions, and records ==

	There seems to be a bit of a dispute. Shall we try to find some kind of consensus on the talkpage, rather than editwarring?<br>
	The original text of the article said that TGV had lost its record for the fastest scheduled train service (a Chinese rail service took the record). FlyAkwa then changed that to say that TGV still holds the record, due to the announcement that the Chinese rail minister had ordered a slowdown of rail services during the crash. I think this is wrong, because:
	#The cited by FlyAkwa explicitly contradicts them and supports my point; timetables still show trains scheduled at . I'm glad that FlyAkwa ; if FlyAkwa had read it they would not have assumed that it supported their point.
	#The cited by FlyAkwa is about a cap of maximum speeds, not average speeds between stops on a timetable. 300 is still significantly higher than 279. The source says nothing about the speed cap being permanent, and nor should it, as a kneejerk reaction following a rail accident.
	#Neither source retrospectively changes the speed of trains which have run for the last couple of years.
	As and when a reliable source actually says that the TGV has regained its record, I would be happy to update the article accordingly. I expect more details will be available in the media in the next few weeks... ] (]) 15:57, 29 July 2011 (UTC)

	: From 2008 to July 2011, speed on the Wuhan-Guangzhou High-Speed Railway was 350 km/h. The best time was "Wuhan-Guangzhou North" in about 2h56, with an average speed of 313 km/h and max speed of 350 km/h.<br> Actual timetables give us as best time Wuhan-Guangzhou South (no more North) in about 3h33, with an average speed of 275 km/h and max speed of 300 km/h.<br> I have lot of other sources about this subject, but in french, it's why I don't cite them.<br> In my sources, lower speed is definitive, with reasons :<br> - To reduce too high energy-consumption<br> - To reduce too high wear<br> - To reduces prices (for travelers)<br> - To raise security.<br> I must be noted that fastest travel from departure to terminal station is still Chinese (it's the travel Wuhan-Guangzhou South, average 275 km/h), but fastest travel from station to station is french (Lorraine TGV - Champagne TGV, average 279 km/h).--] (]) 20:14, 29 July 2011 (UTC)

			I just wanted to point out that the position of Montpellier on the map representing the french tgv network is incorrect.
	::: OK. <br>• Here is an extract in french of a news published in the major paper "]" : "Pour rendre les trains plus sûrs mais aussi moins onéreux, le ministère des Chemins de fer a limité, à compter du 1er juillet, '''la vitesse maximale de l’ensemble des trains à 300 km/h, contre 350 km/h''' auparavant."<br>• On this tour operator portal ] : "On est loin du triomphalisme des dirigeants chinois annonçant il y a moins d’un mois des vitesses de croisière de 380 km/h pour ces trains !

"<br>• In this official Chinese online paper "]" : "ministre Liu Zhijun, a dit que '''les trains à grande vitesse rouleront à une vitesse de 300 km/h à compter du 1er juillet prochain, contre les 350 km/h''' annoncés précédemment.'''seules les quatre lignes principales''' Est-Ouest et Nord-Sud du réseau ferré à grande vitesse '''seront équipées de trains roulant à 300 km/h'''."<br>• On this news website dedicated to ecology, ] we can read "La nouvelle qui circulait depuis le début du mois a été confirmée officiellement par le ministère des chemins de fer. '''Les trains qui circulent aujourd’hui à 350 km/h sur les trajets Wuhan/Canton, Zengzhou/Xian et Pékin/Tianjin par exemple vont passer à partir de juillet à 300 km/h'''."<br>Etc.

	{{outdent}}
	OK I've gone and checked the data again and according to the the distance between Lorraine and Champagne stations is 167.5km. The fastest train I can see takes 37 minutes between those two stations. This gives an average speed of 271.6km/h. This is slower than the Wuhan Line which has a maximum speed of 275km/h and slower than the Beijing Shanghai line between Beijing South and Nanjing which takes which according to the ] is 1018.6km which works out at an average speed of 279.1 km/h. Thus the Chinese are still faster I'm afraid. -- ] <]> 21:04, 2 August 2011 (UTC)

			Thank you !
	:: I'm sorry : the TGV n°5400/5401 from Lille-Europe to Strasbourg, on 17 and 24 September, achieve the 167.5 km in 35 mn, with an '''average speed of 287 km/h''', far beyond your Chinese trains. You can verify with . --] (]) 17:29, 3 August 2011 (UTC)
	:::And that previous speed is slower than speeds achieved by Chinese trains in recent months. What is the basis for your comparison? Timetabled speeds next week? The fastest operational speed achieved in the past? Or something else? ] (]) 18:02, 3 August 2011 (UTC)
	::::OK I downloaded the timetable and the French do have a service at 8:23 on a saturday morning from Champagne to Lorraine which only takes 35 minutes. However its only one train a week in one direction. It could easily be that someone made a mistake with the timetable, or that the French want to win the contest of having a scheduled train that's the fastest in the world. Either way while it meets the letter of the criteria (and even that's dubious as they only manage that speed in one direction, if you add the fastest journey times in each direction they get to 279.2km/h) it doesn't really meet the spirit - the Chinese have several trains a day which are as fast as the G1 and they all run every day.
	::::There is also the issue that the timetable only goes to the nearest minute and really for the kind of detail being requested here you need a more accurate timetable for the French - the Chinese not so much as their fastest run is for 1000km which is much further so the average speed doesn't change as much, but even so it would probably be useful.
	::::I think the best solution is to say that the French lost the record in 2009 which is true and then not worry about the later record as basically both trains are equally fast. -- ] <]> 20:18, 3 August 2011 (UTC)

With regards to Chinese sources they are perfectly reliable for this kind of thing. Watches aren't illegal in China. -- ] <]> 17:17, 4 August 2011 (UTC)

	On a related issue, to ]: the French Misplaced Pages article "Accident ferroviaire de 2011 a Wenzhou" is very weak, the French Misplaced Pages administrators are requesting that the article be improved. The English Misplaced Pages article "]" is much better (confession: I wrote the "signalling" section of this article). As a fluent French speaker, perhaps you might be interested in expanding the French article, using info in ] as a source?

	:: Hello Prospero10. Thank you for your intervention, and for reverting the pages, against Chinese propagandists.<br> As you says in your last sentence, all speed in china has been lowered in two steps : <br> • After the supplanting of railways minister Liu Zhijun, maximum speed has been lowered from 350 to 300 km/h for lot of reasons (high energy-consumption, high wear, prices, low security).] <br> • Following the Wenzhou accident, << Sheng Guangzu, the Minister of Railways, said that railways with a maximum speed of 350 km per hour (kph) will run at 300 kph, while those with a maximum speed of 250 kph will run at 200 kph.

But Chineses don't wonder about that. --] (]) 20:50, 31 August 2011 (UTC)

			== LGV network map ==
	What a controversy! I updated the sentence in 'Milestones' on 'highest scheduled speed' on August 20, WITHOUT CONSULTING THIS TALK PAGE (sorry!) but using the up-to-date 'China Train Guide' timetable which gives a fastest Wuhan-Guangzhou time of 3 hours 33 minutes. The helpful French links given above indicate that this slowdown occurred as of July 1st, and not following the Wenzhou train collision of July 23 as I thought.

			That map is very, very old! And the caption does not provide any indication that the map is very, very old.
	I suggest that we cool down this battle, it's not a major issue. Since July 1st, 2011, the fastest Chinese trains have the same cruising speed of 300 km/h as do nearly all TGV's, except on the TGV Est where 320 km/h is authorized. Differences in point-to-point speeds are no longer major.

			How about replacing it with the map from the French version of this article? ] (]) 00:38, 21 July 2024 (UTC)
	In the future, it will be interesting to see whether the Chinese trains are speeded up over 300 km/h. Both Siemens (CRH3 trains)and Kawasaki (CRH2 trains) have reportedly warned that this would create risks. Again, I suggest we tone down this discussion.] (]) 00:32, 23 August 2011 (UTC)
