Sad that Shanghai Maglev is definitely dead.
I take all these claims of the CIT500 breaking the current speed record with a grain of salt. Why hasn't there been more mainstream international publicity if the trainset has really broken the record?

By the way 380D is most expansive one among the 380km/h capable ones, right? I remember its cost was 4 billion for 80 of them?

Why is it that all of the trainsets from China either...

1. Look horrible in concept art, but are suddenly beautiful in real life?

My guess, from a non-engineering perspective XD
1. Engineers and designers spent most of their time on the actual train and not the CG.
2. Engineers and designers spent too much of their time drawing nice CGs before realizing the deadline is near and cobbles something horrible together just in time.

There are also unsubstantiated claims that the set hit 605 km/h last march (2013). No confirmation either.

On test stand, not actually traveling on tracks.

I thought this is public knowledge.

In August 2012 it was reported that at the moment CRH500's test stand speed record was 575km/h and engineers are testing with higher speed, we don't know when did the 575km/h test occur.
http://www.skyscrapercity.com/showpo...postcount=1124

Nov 2012 CCTV reports CRH500 has a maximum design speed above 600km/h
http://news.cntv.cn/china/20121128/103040.shtml

This fairly reputable blog is where the 603km/h test stand speed initially came from.

Well, here is from Xinhua and with information from xianghunet. The train achieved 605 kmph on "lab test track" and will have a test run in Hangzhou-Changsha HSR line (Specifically the section between Pingxiang North and Nanchang) before it's opening. So it's basically happening now, and we'll need to wait for news in the coming month to see how fast it run on non-lab tracks.

昨天有消息说,萍乡北——南昌西段有望出现冲刺600公里/小时的速度。跑出这一速度的,将是CIT-500车型的列车,官方称为“更高速度试验列车”,车迷们则称为“500公里实验列车”。2011年12月25日在中国南车四方股份公司下线,设计时速500公里。这种列车一共6个车厢,每个车厢都是动力车,整体造型犹如一把剑。

中国南车集团一位宣传干事说,“这种车已经在实验室跑出了605公里的时速,下一步就需要实地去跑。”他说,杭长高铁是CIT-500冲刺600公里时速的选择之一,在这里冲高的可能性比较大,但是还没有最后确定。
EDIT:
Interestingly, CSR has placed CIT-500 on it's website just last month, perhaps they will announce the results soon.

Thank you for the links!

I just checked Google Earth and the section between Pingxiang and Nanchange indeed is pretty flat, still viaducts and tunnels but the grade shouldn't be too bad. It would be a good place to break the record.

It will be a dream come true to see the CIT-500 run on the rails. New world speed record I hope.

Reaching 600 on a lab track without air resistance is a totally different game to the real world though, I would expect something in the low to mid 500s to be achieved.

and Part 2 of that at http://blog.sina.com.cn/s/blog_5a53af350102e0vm.html
has a PR movie showing some of the buillding and testing. I'm still skeptical of how much a static roller test can actually test, like e.g. bogie yaw, and passing pressure wave response. I read comments on another blog shortly after opening of the Beijing-Shanghai 350km/hr service, that bogie yaw was something the Chinese "could do better" at.

Very high 400s (486.1km/h) is already achieved even by non-modified (i.e one that is daily used in the revenue operations) CRH380A. As a test train CIT500 should reach very high 500s, at least that's my expectation.

If an unmodified CRH380A can run 100km/h above its designed operating speed then I think it's safe to assume a CRH500 can run at 600km/h as it's a specially designed very high speed demonstrator. It reached above 600km/h on test stand a year and half ago and I doubt those guys have been idling.
