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

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?

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.

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

China's high-speed trains pre-CRH

I think this topic deserves its own thread, but if local mods feel otherwise please feel free to merge this with one of the existing Chinese railways threads.

Now, what I suspect a lot of people here don't know, is that before the very high-profile CRH era, the MOR and its factories developed a few of China's own prototype models.

China Star

(Images from Hudong Tupian)







Formation - push+pull and 9 carriages

Top operational speed - 270 km/h

This train is formed of 2 electric locomotives one at each end, and 9 carriages in the middle. Top operational speed is 270 km/h though in a test-run as early as 2003 it achieved 321 km/h.

And Blue Arrow,



(Picture from http://www.ce.cn/xwzx/gnsz/gdxw/2009...20192685.shtml)



(Picture from Baidu http://hi.baidu.com/stepdo/blog/item...3d7cae2cc.html)

The blue arrow has a formation of push+pull+5 carriages, and is designed for 200 km/h running. The train was developed between 1998 and 2000 and test run speed reached 305 km/h. Seems it has been in trial passenger service in 2009 and 2010 in Sichuan though exact details are hard to compile and information on the internet has discrepencies.

For probably very valid reasons MOR opted for importing European and Japanese models for the CRH network. These trains seemed to have been forgotten somehow, with further development of the China Star practically abandoned.

2010.11.29 CRH380A-6041L scored 475km/h, Final test will lauch tomorrow,

CRH380BL lost to CRH380AL, though the sources didn't disclose it's top speed in the trail run

By comparing just the looks of them, 380A looks much more aerodynamic.

It actually would make sense that the 380AL can achieve a higher top speed than the 380BL. The AL has 2040 kW more power than the BL. And I'm not sure about the specifications of the BL, but I would assume that the AL has an overall lighter weight than the BL. But then again, I can't be sure about that one.

I think MOR won't publish any speed data until the contest is completed, at this point those speeds can be considered trade secret. But boy 475 sure is fast, not 575 fast, but getting there.

Obviously the Chinese have had a huge leg up from the European train manufacutrers, but their progress has been fantastic since then.

I guess for China the speed is a premium. In the UK i know it is not really worthwhile having a line in excess of 400kph as distances between destinations is not that great, but given the size of China, having a 500kph traim could be the difference between sucess or failure on long distance routes.

its nice to have thousands of engineers working for you for slightly more than a bowl of rice

Your trite hyperboles, on the other hand, are neither nice nor interesting.

you apparently neither have a clue about the facts, nor a clue about the meaning of "hyperbole". Hyperboles are never true.

Actually, the 475km/h speed appears to have been clocked by an unmodified train-set (CRH380AL), so it does not make much sense to compare it with the French record, which was made with a mega-beefed-up configuration set up for the express purpose of creating a (pretty meaningless) speed record.
