CHINA | High Speed Trainsets

Right, the current test tracks are probably not straight and long enough to get to 455kph, it seems to me that at least now there is no rush in China to beat the 574kph conventional rail speed record.

I am always told at high speed double the speed require eightfold the power, well, for a ball, not a train...

Exactly. And that is due to wind resistance.

Problem is: China is a huge economy and trading partner for the West. Even though they don't respect intellectual rights, the West has to shut up and deal with it, so we can keep on doing business with them. Actually it's not unheard off that Western companies have to forge joint ventures with Chinese companies that engaged in product piracy before. That way they can at least get a share of the profit that is done with the stolen IP. The downside is that we transfer technology down there and in the long run it will harm our economy.

Despite all the Chinese propaganda here, China could have never achieved its high speed rail project without massive foreign technology and help. Nevertheless it is quite impressive. Yet all these claims should be taken with caution, as China is not exactly known for being a very open society and caring much about freedom of speech and information.

You mean like how Europe was basically chucking spears and shooting arrows at one another for thousands of years before being exposed to Chinese and other foreign weapons?

the newest source imply top speed of CRH380A-6041L exceeded 480Km/h

CRH380B-6402L starts test run today

[foxmulder]

More than 480km/h?? That is nice, much higher than what I was expecting. Hope to see some pictures and official announcements.

Visit Apple co. in the bay area and take a look yourself.

Where is your proof, please post here. Would be interesting to see

any idea why there is no official report on the test results?
I hope they could at least disclose some info before the UIC HSR conference.

I think there will be official news published before UIC HSR conference, IMO the MOR won't confirm any infomations until the final results is decided

Has anyone taken a photo of the speed display inside the carriage of a CRH-380 showing 380 km/h?

[rheintram]

Why can't China simply publish the information about these trains and technical data just like any other company and country does?

I'd say:

Why China doenst want to simply publish the information about these trains and technical data just like any other company and country does?

Why China doenst care of simply publish the information about these trains and technical data just like any other company and country does?

Anyone? 379 will do...

As far as I know 380 kph max service speed trains are allocated for Beijing-Shanghai HSR line scheduled to open later next year, for the lines currently for passenger service it only goes up to 350 kph. Don't know what you are looking for though, there are videos of 416 kph on test runs, and 350 kph shots from passengers, all within top few search results on YouTube.

I'm not sure how detailed you want to get, simple technical specifications like power and traction control are around the internet, its not hard to find them. More detailed technical papers you'll probably need to subscribe to Chinese engineering journals, same case with "other countries". If you are looking for detailed blueprints I don't think you'll find anyone publishing those.

maybe because it doesn't matter except to a few geeks like you?

Well there's one thing for sure - that the MOR is not known for their enthusiast-friendliness.
