3.The bogie is redesigned to support high speed. The new train's derail coefficient has been reduced by .37 from .73 of old train. The new train running at higher speed is safer than the old train running at lower speed.
4.The noisy is at 67dB when running at 350km/h, which is similar to the old trains running at 250km/h.
5.The strength of train is designed at 6000MPa, which is 50% higher than international standard of 4000MPa.
WOW!!!

NOTE:

Canada can never afford to build Ballast less HST track for a long time to come for Toronto -- Montreal corridor, let alone from Vancouver to Halifax.
Especially if Canuckese are always brown-nosing its Southern neighbor and spending money unnecessarily on ice hockey and beer.
Kind of an ignorant comment altogether and a completely troll post. Moderators?

If you actually read my post, you'd notice that I was actually complimenting China being able to do such great projects that Canada never could for most of it.

For the record, I'm actually Chinese and not born in Canada.

so according to CSR, IRJ and Bird01:

As CSR claimed, the overall design of CRH380A reflects ten system innovations.

low-resistance streamline head, The nose design of the train has a resistance coefficient of <0.13.

vibration mode system matching, it has optimised the bogie to match the performance of the body and improved the train's interior structure to improve the car body's natural frequency, which helps reduce the body's structural vibration during the high-speed running and improve ride comfort.

high-air-tightness body, enabling the train body air tightness to decrease from 4000Pa to 1000Pa in more than 180 seconds. The pressure change rate inside the train is less than 200Pa/s, with the maximum pressure change inside the train remaining below 800Pa compared with the standard value of 1000Pa. This ensures good ride quality at high speed.

safe and reliable high-speed bogie, The bogie is redesigned to support high speed. The new train's derail coefficient is 0.34 at speed of 386.3km/h while the maximun derail coefficient of CRH2A is 0.73.

advanced noise control technology, By reducing sources of noise and adopting new sound absorbing and insulating materials, CSR has been able to control noise inside the train,The noisy is at 67dB - 69db when running at 350km/h, which is similar to the CRH2A running at 250km/h.

high-performance traction system, with YQ-365 motors manufacturer by CSR zhuzhou electric co.,Ltd and CI11 Traction converter manufacturer by Zhuzhou times electric co.,Ltd.

high-speed dual-pantograph current-receiving performance.

safe and environment-friendly brake system,regenerative braking should result in the energy feedback rate hitting 90%.

human-oriented passenger interface.

outstanding intelligent performance.

You forgot to mention that the interconnect system of the Tianhe 1A is entirely Chinese developed which runs faster than an infiniband interconnect.

Developing an interconnect system has been the greatest bottleneck in the history of parallel supercomputer performance.

China is becoming most innovative country in rail industry. I am waiting for CRH500.

I hope that someday this train would go from China to Europe by tran-Asian high speed rail. It's not a joke China just gave it 45 bln $ loan to Turkey to build high-speed silk route it in Turkey. The same agreement with Bulgaria is in final phase.

Well, the loan to turkey is smt like 28 billion but nevertheless it is huge by any means. I believe it is highly probable that we can see CRH380s in Turkey in coming years.

What real data do we know about de CRH380A ? because we┤re talking if it is a beautifull train and so that, but is there any more especific data, tech info and most important tech drawings about the train ?
I┤ve read about the origin of the bogies, in some photos the roof tails seems to be so similar to a japanese HST model, What about the power electronic transformers, pantographs etc.. In westerns manufactures it┤s normal to show some tech data in the launching of a new High Speed Train. I really can┤t say something about this train because there is no available real data of it, or that┤s what I thing at least.

CNR Changchun Railway Vehicle designed a new type of High Speed train front, the official news was published by November 2 2010. and the work is completed.the outlook is described as cheetah by the news.

http://www.chinacnr.com/272-619-3429.aspx

according to rumors on different Chinese forums, this new design will be used on CNR Changchun Railway Vehicle version of CRH380B, so the CRH380B will have two different shapes???

just added the folloeing paragraph to wikipedia,

http://en.wikipedia.org/wiki/High-sp...creasing_speed

sorry for my poor English, I believe I've missed some important part, so let's take a look at it and consider what kind of infomations can be added in addition.

Quote:
Localization and increasing speed
Digestion and re-innovation is one of the major consideration of the Chinese MOR when China decided to import foreign technologies.

With the technologies achieved from foreign companies, Chinese factories are able to produce components of the vehicles. Mitsubishi Electric transfer MT205 traction motor and ATM9 transformer to CSR Zhuzhou Electric, Hitachi transfer YJ92A traction motor to Yongji Electric, Alstom transfer YJ87A Traction motor to Yongji Electric, Siemens transfer TSG series pantograph to Zhuzhou Gofront Electric. most of the component of the CRH trains manufacturer by Chinese companies are from local suppliers, few parts of them are imported.

During June 2005 and September 2005, The Chinese Ministry of Railways launched bidding for High speed trains with a top speed of 350 km/h. as most of the main High Speed Rail lines are designed with top speed of 350km/h or higher. Along with CRH3C, produce by Siemens and CNR Tangshan. CSR Sifang bid 60 sets of CRH2C.

Within two years of co-operate with Kawasaki to produce 60 CRH2A sets. CSR had “digested” the technology required for their manufacture. [26]. since then CSR is no longer co-operating with Kawasaki.[27] Starting from 2008, all CRH2 trains, includes CRH2B, CRH2C and CRH2E were designed and manufactured under key technology developments made by Sifang without Kawasaki. according to CSR president Zhang Chenghong, CSR "made the bold move of forming a systemic development platform for high-speed locomotives and further upgrading its design and manufacturing technology. Later, we began to independently develop high-speed CRH trains with a maximum velocity of 300-350 kilometers per hour, which eventually rolled off the production line in December 2007." [28]

In order to provide higher capacity and more comfortable service in the Jinghu Railway, as the travel time from Beijing to Shanghai is around 10 hours under top speed of 200 km/h in the upgrade railway. on October, 2007, the MOR ordered 70 16-car trainsets from CSR Sifang and BST, includes 10 sets of CRH1B and 20 sets of CRH2B seating trains, 20 sets of CRH1E and 20 sets of CRH2E sleeper trains.

Technical support is one of the most important factor to make Bombardier the first and only company who has a Chinese-foreign joint venture manufacturing railway passenger cars and rolling stock in China. the BST company was established by 1998, as an excellent example of foreign technology applied to the renewal of state-owned enterprises in China. in a interview with Zhang Jianwei, President and Chief Country Representative of Bombardier China, he explained Bombardier's policy in China is "to transfer whatever Bombardier have in the world to the joint venture, to transfer what China market needs without requirement".[29] not like other series who has prototype imported from other countries, all of the CRH1 trains are manufactured in Qingdao.

Construction of China and World's first ever high speed rail with designed speed 380 km/h, the Beijing - Shanghai high speed rail, began on April 18, 2008.at the same year, the MOR lauched three project CRH1-350 (Bombardier and BST, designated as CRH380C/CL),CRH2-350 (CSR, designated as CRH380A/AL),and CRH3-350 (CNR and Siemens, designated as CRH380B/BL), to develop new generation of CRH trains with top operation speed 380km/h. a total of 400 new generation trains was ordered. CRH380A come into regular service at the Shanghai-Hangzhou High speed rail by October 26, 2010. which is the first high speed train developed by China[30].

On October 19, 2010, the MOR declared China has begun research and development on a new "super-speed" railway technology, will increase the average speed of trains to over 500 kilometers per hour.[31]

Once again thanks for posting. This new design looks kinda cute ^.^b
Maybe it'll be the future mascot of CRH ?

I do not think so. The new design is for CRH380B, the Velaro design is for CRH380BL.

This past few days I read some article that CRH380 are pirate technology from Japanese shinkansen but for me it's not beacuse if we look the train the design are originally concept by the Chinese they mix the design from 2 different high speed train i think the one is from fastech 360S and from velaro because if we look the window near the driver cab and the interior of the train is very different from shinkansen because some latest shinkansen have no more dining car or any private compartment, So for me the CRH 380A are originally chinese technology.

This shows the CRH380 is indigenous Chinese design.
The Chinese can make a number of trains from each of these 20 designs.

It begs the question, "Why did they select the one that resembles Japanese design the most?"

The truth is somewhere in the middle (like always) It's not genuine Chinese and of course not a pure replica of other trains
I think it's a melting pot of Chinese technologies and Japan, Germany etc,
It's very hard to define in our days what is yours and mine in the world of globalization
