The tracks are standard gauge, but the loading gauge is slightly wide, so they can fit in 5 seats per row.

It says CRH380A's critical speed is 550km/h, I wonder what's the critical speed of the Higher Speed Test Train.

What does critical speed even mean?

Chinese and Indian trains are the only trains I have seen with 15 and 20 bogies.

I think, it means max speed reachable without starting self destruction.

380A was designed to run at 380km/h in service so it was tested routinely at speeds above 450km/h (20% head room between service speed and maximum speed it can make safely) Apparently, it could have made more...

I think that the critical speed is where the boogies start to have too much hunting oscillation and other vibrations, for them to be deemed safe.

Actually if it has a maximum service speed of 380 km/h it is sufficient to test it at 418km/h. (Max service speed +10%)

The CRH380A was initially designed to be CRH400A with a 400km/h service speed, but that was deemed crazy and reduced to 380km/h. So technically they should test it 440km/h, but I get what you are saying, which I think was why it was initially tested at 416km/h when the train was introduced on the Shanghai-Hangzhou line. Now we know it can safely travel at 486km/h without any modifications.

I'm still thinking about the geometry of the headlights on the CRH380C.

I really like the flat nose CRH6. I cannot wait to see that blasting down the tracks. Is this version also going to get the Cinova marketing name? I forgot what Cinova is supposed to mean.


China has the most beautiful variety of high speed trains with my favorites being the CRH3, CRH5 and this flat nose CHR6.

Cinova means "China new", a designation for CRH6 trains and EMU's by CSR Qingdao, with a much more aerodynamic nose. The flat nose version CRH6's are designed by CSR Jiangmen in Guangdong Province and the trains are to be used to run the Intercity route in the pan Pearl River Delta area.
The flat nose can be improved by a better paint job. The version right now looks quite perfunctory.

Thanks for the wonderful posting. I think they need design talents like you in CRH.I can see that the geometry of the CRH3 nose can be aerodynamic as well as whimsical. I love the grid design of the tunnels and the robust power pylons. I have been wondering how China Rail was going to do with the powerful winds in Xinjiang. A wind gallery of 67 km is to be built near the Tarim Basin, along the Lanzhou-Urumqi hsr. All they need is strong and beautiful pylons you designed to withstand the wind. Good jobs
