If you make a comparison with the people pushing I think you'll notice that it's a bit small.
It's probably a 75% scale or something.

Could someone who's a member of that site post the picture for us here?
its pretty easy to register, all you have to do is supply a username, password, email address, 2 verification codes, and agree to the terms and conditions. I think it's rather your lack of Chinese comprehension that is hindering your efforts to register, as I just easily registered a new account in 15 secs. I can help you register if you want, just supply the username, password, and email you want, and I'll give the account to you after I create it.

Anyway here's the photo:

I am not sure you understand what the problem is. Registering is no problem. But you do not get the full-membership status just by registering. They are supposed to review my application and notify me at the email account I gave them. Yet months go by and I haven't seen anything yet in my email account.

Without a full-membership status (whatever they call it) you cannot view the photo attachments to certain posts.

It's definitely not an automatic process. They obviously employ censors who personally review each registration and decide the German email account I gave them is not good enough, or whatever.

seems like this is new, when I registered years ago I didn't have this problem or any delays in registering, but I guess they are trying to be as annoying as possible now...

Are you sure your activation mail didn't arrive in your spam box?
Although it's possible they use manual activation - which would be a pain, the usual problem is more that such activation mails end up in a spam folder and as such are overlooked...

@BarbarianManchurian / Goldenox

my apologies, I confused ourail.com with ditiezu.com. The former has the censorial policies I described. The latter, as I just found out, actually doesn't. I could become a full-member by uploading a personal picture (though not necessary of my person).

But the better sites (hasea.com, ourail.com) remain closed or member-ship censored.

The train that's being pushed sideways is a MOCKUP that's being displayed in the Jilin Province Pavilion at the Shanghai 2010 expo.

There are rumors that it is a model of the 500km/h test train that's currently under development. Only a rumor though.

500km/h? I have no doubt it's technically possible to develop one (just as the current top-speed records prove) but wouldn't it be too inefficient due to the forces of friction with conventional rails and wheels? Even if it could actually run at such speed, operating and maintenance costs would many times exceed those of trains running at 300-350km/h. Hence if they want 500km/h the only reasonable option is maglev which would do much better at such speed.

point is to beat the French. As in the my long and round object is faster.

Will they build something that'll commercially operate at that speed? Nobody's planning for it at this time.

Are there any pictures of the CRH3-380 (not this other project) in the public domain?

It's designed by Shenyang Aircraft Corp, whose replica fighter jet J-11B(a clone of Su-27) was refused to be accepted by Chinese airforce due to an instability in the air.

No it is not. Too much wear and tear on the track. The realistic service speed limit of a conventional high speed train is 360 km/hr. Higher commercial service speeds would require maglev.

Yes, maglev is the only option for a commercial service speed in excess of 360 km/hr.

Global Rail Tech Conductor

China becomes a world leader in high-speed railway innovation after absorbing foreign technologies and making breakthroughs of its own
By LAN XINZHEN


Most everyday train passengers don't have time, or reason, to ponder the technicalities of the rails, wheels and engines beneath his or her feet. But inevitably questions will pop up. What kind of quality technologies do China's high-speed railways utilize? How are they maintained? And are they safe?

"China has mastered a complete set of high-speed railway technologies that integrate designing, construction, equipment manufacturing, train control and system integration, as well as daily operation and management, forming a high-speed railway technology system with independent intellectual property rights at a global advanced level," said a news release from the Ministry of Railways (MOR).

The release also says that although high-speed railway technologies originated in Japan, Germany and France, China has made independent innovations when absorbing technologies from abroad. With a series of significant technological achievements, China has become a world leader in high-speed railway technologies. The fastest train operating in the world is in China (CRH trains), and it features the best system integration capabilities, covers the longest distance and is the largest construction project of its kind anywhere in the world.

Thanks to China's achievements in high-speed rail construction, Beijing is honored to host the Seventh World Congress on High Speed Rail in December 2010.

Technological breakthroughs

China currently has three high-speed rails operating above 350 km per hour, all of which were built on different terrain, presenting multiple challenges—the Beijing-Tianjin Intercity Railway is built on a mollisoil bed, Wuhan-Guangzhou High-Speed Railway on a karst bed and Zhengzhou-Xi'an High-Speed Railway on a collapsible loess bed. Construction of railways, particularly high-speed railways, on such geological conditions is unprecedented, even in Japan, Germany and France. To build the railways, China had to overcome numerous design obstacles before setting out to complete the high-speed projects.

The MOR noted the three high-speed railways are operating stably and efficiently, a testament to China's ability to master treatment technologies of railway beds with complicated geological conditions.

To save land, an array of bridges were built during the construction of high-speed railways, particularly over sections that span major rivers. On Chinese high-speed railways operating now, three of these viaducts stand out: the Wuhan Tianxingzhou Bridge, Nanjing Dashengguan Yangtze River Bridge and Jinan Yellow River Bridge. The three structures hold world records in terms of span, load-bearing capacity and width.

Tunnel construction also reflects the degree of difficulty facing China as it strives to construct a massive high-speed network. The Wuhan-Guangzhou High-Speed Railway has tunnels running through the Dayao Mountain and crossing the Liuyang River near Changsha, capital of Hunan Province. Cross-sections of these tunnels are 160 meters wide, and trains pass through at speeds of 350 km per hour, an unprecedented accomplishment among high-speed rails worldwide.

As for track technologies, high-speed railways in France use ballasted tracks (tracks stabilized with small, crushed stones), while those in Germany and Japan use ballastless tracks. According to the MOR release, with systematic and comprehensive research on ballastless tracks, China has solved the problem of electric current coverage between ballastless tracks and rails, which other countries have never encountered.

China also has high-speed railways with seamless tracks, such as the Beijing-Tianjin Intercity Railway. On the 120-km railway, there is not a single seam. He Huawu, chief engineer of the MOR, said using seamless tracks in China is a thorny problem due to its vast territory and range of temperatures between different regions and seasons. After years of research and a hefty financial commitment, China has developed the most advanced technologies in the world in both ballastless and seamless tracks.

High-speed innovator

The MOR release said China's high-speed train technologies have reached the world's most advanced level. Based on mastering core technologies for high-speed trains capable of traveling 200-250 km per hour—the same as those abroad—China has solved the difficulties that restrict speed increases. With innovations in key technologies and manufacturing technologies of its own, China has successfully established a technology platform for trains with a speed of 350 km per hour.

China-made CRH high-speed trains now operate widely on high-speed lines nationwide. The CRH trains have risen to the advanced level among world high-speed trains for their demonstrated excellence on the Beijing-Tianjin, Wuhan-Guangzhou and Zhengzhou-Xi'an high-speed lines, in addition to the operating speed, large transportation volume, energy-saving and environmentally friendly capability, and comfort of each train.

Overseas competitors, He said, have yet to match the speed of China's trains. The Super Express, or Shinkansen, is the masterpiece of Japan, but runs at only 300 km per hour, while French and German high-speed trains run at around 320 km per hour and 300 km per hour, respectively.

China, while producing the world's fastest trains, hasn't ceased efforts to produce even higher-speed rails. To meet the demand for a Beijing-Shanghai high-speed corridor, China has completed the design work for trains capable of traveling at more than 350 km per hour, and progress is being made on the production of such trains.

The Chinese Train Control System (CTCS)—the mechanism used to coordinate China's massive rail network—has also surpassed the present world advanced level. Currently, most Chinese rails apply the CTCS-2 technology, which is similar to the high-speed train control system used abroad. In addition, a CTCS-3 system has been developed to ensure the safe operation of high-speed trains of 350 km per hour with train intervals of three minutes. The CTCS-3 system has been applied to the Wuhan-Guangzhou High-Speed Railway and the Zhengzhou-Xi'an High-Speed Railway with positive results.

Since China is still in the primary stage of high-speed railway development, many railway stations serve both high-speed and standard trains, which presents varying safety requirements, especially when trains are entering and leaving the stations.

"We have solved this problem and unveiled all the hidden perils caused by pulling in trains from multiple tracks," He said.

China's routine maintenance system for high-speed railways integrates some of the most advanced technologies in the world. This technology combines sub-systems such as CRH trains, telecom signals, operation controls and passenger transportation. Specialized personnel are responsible for checking the integrated data and then making subtle adjustments to the equipment based on the collected data in order to optimize the whole system.

The integrated technology will not only allow China's high-speed rails to reach their goal of breaking speeds of 350 km per hour, but also provide new levels of comfort and safety where not even full beverage glasses will spill during the course of any trip.

The MOR release also outlined plans for comprehensive high-speed checking trains to monitor the infrastructure with automated equipment. In addition, the MOR has developed early-warning technologies to monitor natural disasters in real time.

Exporting technologies

China has reached a series of agreements with the United States, Russia, Brazil, Saudi Arab and Venezuela on cooperation in high-speed railway construction. Some of the projects are making significant headway.

The MOR release says it will share advanced and mature high-speed railway technologies with other countries in line with the principle of mutual benefit and win-win cooperation to promote high-speed railway development worldwide.

As chief engineer of the MOR and mastermind for designing and manufacturing China's high-speed railways, He is quite proud of the independent innovation and breakthroughs his country has made.

He said China has complete independent intellectual property rights over its high-speed railways, with 946 patents pending. And so far, there have been no intellectual property right disputes between China and any foreign companies in the high-speed railway sector.

I reckon that ourail.com is up and running, though it does not accept new members. I am sure some readers of this forum are members of that (and other) chinese railway fan sites Any news/photos about the CRH380 and CRH3-380 on ourail.com?
