I guess that means CRH1A 250 NG, which is the Bombardier Zefiro 250 NG (the CRH1A is a Bombardier Regina, very different and older).


The three HS Bombardier designs (Zefiro 250, Zefiro 380 and V300 Zefiro with AnsaldoBreda) are almost simultaneous.


From left to right: CRH1A 250 NG, CRH380D, CRH1E (from Zefiro 250) and CRH1A (from Regina)

The CRH380D looks cool but I keep seeing the old CRH1 when I look at the rest of the train. Am I wrong to think the CRH1 is old high speed rail technology? From what I understand the CRH380D is an upgraded CRH1.
It's nonsense to judge high speed trainsets on cosmetic appearance. Yes, the CRH1 is an older design, based on the Bombardier (ex-Adtranz) Regina trainset used in Sweden, and was likely selected as it has a wider carbody profile to better utilize the Chinese loading gauge. The CRH380D is a thoroughly modern design based on the Zefiro 380- it shares a family resemblance with the Regina on the carbody sides, but the innards are likely quite different.

To complete the comparison of the Bombardier Zefiro family it lacked the next ETR 1000 to begin circulating between Rome and Milan on June 14.

BTW, what is the outcome of the CRH500 /CRH-X Cobra) train with its hight ambitions as a test train? I think one of the aims was to make it beat the TGV world record...

When googling, I mostly find news articles from 2011-2012 announcing this powerful train, but there seem to be no more recent news about the achievements and further developments or successor trains. Any ideas?


http://singularityhub.com/2012/01/18...whats-to-come/

Also something I could not find out: Do the maximum train and line speeds have been restored to their designed operational speed of 350-380km/h? Those limits which were lowered in 2011 to 300km/h and less?

No. If this was to happen we can be sure that it would be announced and celebrated in this thread.

Thanks for the link, yeah the car sides look the same but as mentioned the insides are much different . I thought it the CRH380D was somehow an upgraded CRH1.

Since it seems that no one answered, I will with my bad English. Sorry

The current maximum speed is 309 km/h, and was never circulated to 380 in commercial service.

Following the resignation (February 2011) for corruption of former Minister of Railways announced in April his successor a change in policy on HS: the speed of the HSR will be reduced from 350 to 300 km/h in July, and the rest of PDL from 250 to 200. The reasons given were: reducing energy consumption, lowering prices to fill the trains and for safety !!. Shortly after an "adjunct" nuance the words of his boss: the speed reduction would be only on lines with low occupancy and "of course" had nothing to do with security.

Meanwhile, on June 30, the Beijing-Shanghai line was inaugurated. It is the only projected to 380 km/h, but after many problems during testing was commissioned in 300, announcing the 350 "before year end" and 380 "some time later". In July presented problems of signaling and new trains CRH380A.
July 1 became effective speed reduction on lines with low occupancy.
23 of the same month the accident Wenzhou. In this accident he had nothing to do speed, so they have told: there was a storm, the first train (CRH1B # 46) stopped by a failure in a substation, signals broke down, it was getting dark ... and the second train ( the CRH2E No. 139, both entitled to 250 km/h) hit the first train.
In that vein, the SE Coastal PDL, full speed before July 1 was 250, and at that time was reduced, so the accident occurred in a limited line and 200 km/h. I do not know how fast the scope occurred, although it would not be too high: they derailed the last 2 and the first 4 cars; the problem is that it was on a viaduct and 3 of them fell into the void.
After the accident nor the maximum speed of 350 km/h was reduced immediately, but in stages: during August fell at least between Beijing and Tianjin (16), Shanghai-Hangzhou and Wuhan-Guangzhou (the 28). Also in August, but nothing seems to indicate a relationship, all trains were 380A factory to make changes, since continued to fail.

Sources (in English, although the entrance is in Spanish)
................................................
Ya que parece que nadie te contesta, lo haré con mi mal inglés. Lo siento.
La velocidad máxima actual es de 309 km/h, y nunca llegó a circular a 380 en servicio comercial.
Tras la dimisión (febrero de 2011) por corrupción del anterior ministro de FFCC su sucesor anuncia en abril un cambio en la política sobre la AV: la velocidad de las HSR se reducirá en julio desde los 350 a los 300 km/h, y la del resto de PDL desde los 250 a los 200. Los motivos aducidos fueron: reducir el consumo energético, bajar los precios para llenar los trenes y ¡¡por seguridad!!. Poco después un “adjunto” matizó las palabras de su jefe: la reducción de velocidad sería solo en las líneas con baja ocupación y, “por supuesto”, no tenía nada que ver con la seguridad.
Mientras, el 30 de junio se inauguraba la línea Beijing-Shanghai. Es la única proyectada para 380 km/h, pero, tras muchos problemas durante las pruebas se puso en servicio a 300, anunciándose los 350 “antes de fin de año” y los 380 “algún tiempo después”. En julio ya presentó problemas de señalización y de los nuevos trenes CRH380A.
El 1 de julio entró en vigor la reducción de velocidad en las líneas con baja ocupación.
El 23 del mismo mes se produjo el accidente de Wenzhou. En este accidente nada tuvo que ver la velocidad, por lo que han contado: hubo una tormenta, el primer tren (CRH1B nº 46) se detuvo por un fallo en una subestación, se averiaron las señales, estaba anocheciendo … y el segundo tren (el CRH2E nº 139, ambas series autorizadas a 250 km/h) alcanzó al primero.
En esa línea, la SE Coastal PDL, la velocidad máxima antes del 1 de julio era de 250, y en esa fecha se redujo hasta 200, así que el accidente se produjo en una línea limitada ya a 200 km/h. No sé a qué velocidad se produjo el alcance, aunque no sería demasiado elevada: descarrilaron los 2 últimos y los 4 primeros coches; el problema es que fue en un viaducto y 3 de ellos cayeron al vacío.
Después del accidente tampoco se redujo la velocidad máxima de 350 km/h de forma inmediata, sino de manera escalonada: a lo largo de agosto se redujo al menos entre Beijing y Tianjin (el 16), Shanghai-Hangzhou y Wuhan-Guangzhou (el 28). También en agosto, aunque nada parece indicar una relación, todos los trenes 380A fueron a fábrica para realizar cambios, ya que continuaban fallando.

How a 380km/h trainset can be an 'upgraded' 200/250km/h trainset?

You probably mixed up CRH380D with the new Zefiro 250 design.

Thanks for the answers about the speed reductions still in place on the HSL.
But what about the mentioned CRH500 train which was much mediatized during 2011/2012?
It's roll-out was on December 23, 2011. Its shape had positive reception in this forum too...

" the aerodynamic CRH series train can deliver 22,800 kW of power to its load, allowing it to set speed records in China "


If one tries a "google news" search, last results of this test train are from 2012.
https://www.google.com/search?q=crh5...e=lnms&tbm=nws

Also a standard search gives no recent hints of the achievements of this train...

"China's sword-train truly was a national production. CSR collaborated with both the Ministry of Science and Technology and the Ministry of Railways, the locomotive was produced after more than two years of research with 21 academics and engineers from the Institute of Mechanics, Chinese Academy of Sciences, China Academy of Railway Sciences, Southwest Jiaotong University, Beijing Jiaotong University, and Tongji University. It features materials new to China's railways including advanced carbon fibers, magnesium alloys, and nanometer sized sound insulating particles. "

I understand that the test train should help understand dynamics of commercial train operation at 400 or 500km/h. It would be interesting to learn a bit more about this train that is said to have twice as much power as for example the Zefiro trains.

Though, google.com reveals no link later than 2012. Or has this train been renamed?

I obviate that part because I do not know news about the prototype.
The only thing that is perhaps not well known, is that it has two separate front, one similar to CRH380A and another like the beak of a flamingo, It is the same case as the Japanese prototype FASTECH 360S.




By the way, this old image of Bombardier on CRH1-380, which eventually was the CRH380D:

Train's engineering name is CIT500, external name is CRH380AM. This is its official webpage.
http://www.csrgc.com.cn/g2148/s4916/t67314.aspx

It is part of project 973 to conduct R&D on HSR research, so it more of a technology demostrator than a prototype for an actual product.

http://www.51crh.com/thread-131155-1-1.html


As discussed on this thread before, the train recently underwent speed test on Shanghai-Cha gsha aimming to break 600km/h, but appear to be speed limited to just 385 km/h.

Might be a silly question but are these like the last lines to be constructed before the CRH network is complete? Not that it will ever be complete but will these complete the initial High Speed railway plan?
