The sleeper train looks like the true "dreamliner" ...does it count as a double-decker train like the French TGV?

I'm a little confused as to the floorplans and capacity of the new sleeper train. Are there any better images of the interior or diagrams?

I have to think that the figure of 394 corresponds to half of the train (8 cars), so it should be 788, not many more of the 642 from CRH1E NG because it seems more luxurious.
But I do not know what the 434 (868) .

Chinese Government Grants Two Enterprises EMU Certificates

CR400AF and CR400BF

http://www.yicaiglobal.com/news/5197092.html

(Yicai Global) Jan. 4 – According to a report by China News Services, the National Railway Administration (NRA) of China has granted two domestic electric motor-train unit (EMU) manufacturers Chinese standard EMU model certificates and manufacturing permits, paving the way for the mass production and commercial operation of Chinese EMUs, China News Service reported.

The NRA granted the above certificates to Changchun Railway Vehicles Co. and CRRC Qingdao Sifang Co. yesterday.

The technological industrial chain of China’s EMUs covers the whole country, with almost 300 enterprises directly engaging in the design and manufacturing of major components and spare parts, the NRA says. Currently, the components of nine key technologies and 10 supporting technologies are fully produced by domestic manufacturers.

It was not until the 21th century that China’s EMU technology underwent rapid development. Following the speedy construction of China’s high-speed railway networks, the EMUs produced by China are now crisscrossing the whole country.

Yet China also has electrified slow speed railways.
Does China have any slow speed EMUs?

Since when are CR400AF and CR400BF?
Since when are CR and not CRH?
Since when are 400 and not 350?

Up to now they were CRH350A and B, and the first one circulated for six months on the Dalian – Shenyang line.

The renamed class designation of the CRH train sets was introduced by the NRA during a meeting at the end of Nov 2016.

There would be CR200/CR300/CR400 class categories, covering 100-200kmh/200-300kmh/300-400kmh respectively.

Any idea when the CR400 trains will start running at 400 km/h?

The denomination 400 is for the trains that can circulate between 300 and 400, as voyager221 kindly explained to us.
Precisely the CRH350A is authorized for 350 km/h.
All this is a new denomination that is not going to make the trains go faster.

It is enough to have the trains with the highest commercial speed in history: 350 km/h from 01/08/2008 to 28/08/2011, to have the trains with the current highest commercial maximum speed: 330 km/h in the Shanghai-Kunming PDL (Every time I read it in more publications), and the trains approved at the highest speed ever seen: 380 km/h: CRH380A, B, C and D.
I, at least, hope this year we see the 350 km/h.

But I keep asking:
Since when are CR and not CRH?
Up to now they were CRH350A and B, and the first one is circulated for six months on the Dalian – Shenyang line.

So far these two models CR400AF and CR400BF are only disigned for 350km/h operational top speed with 0.05m/s^2 residual acceleration at 350km/h to overcome weather and grades etc.

Theoretically thay can reach 393km/h at 0% grade with 100% power output, in a test run they both ran at 420km/h in the opposite direction to testify the real world stability of the train sets when passing each other at very high speed.

I don't think there's any plan to operate commercially at 400km/h in the near future in China, although if I remember correctly 400km/h operational speed has been used as a selling point when CRRC bidding Moscow-Kazan HSR project.

Thanks
At least in Europe you need a 10% more sustained speed (350 + 35 = 385) with a rise of 5 mm.

...
If I am not misinformed, with a geometric distance between the centers of each track of five-meter, that is difficult.

Up to now they were CRH350A and B, and the first one is circulated for six months on the Dalian – Shenyang line.
My personal understanding is since there are quite a few new models like CRH6 series and CJ series designed for regional intercity commute, somewhat derived from certain CRH models but not certified as high speed train sets any more. To regulate the developement from different manufacturers within CRRC, a new broader class designation is required.

The production versions of the CRH350s will certainly be renamed as CR400AF and CR400BF, we will see if the existing models like CRH380A/B will change their model names accordingly.

Do the drivers have to cross the tracks in front of the trains at grade? If I was a driver for a train in the middle, I'd be freaking out haha. How do they manage this people traffic on the tracks anyway, especially with such a big yard?

I don't see what the problem would be with that. The tracks themselves are not electrified.

You can see the walkway leading across the tracks in the photos.
It's a bit in front of the leading cars so you would see if any train moved, and since it's a stabling yard the speeds are most likely kept quite low for people to safely pass on the walkway.
