At these high velocities air resistance becomes a huge problem, making it impracticable. Wasn't this the main reason for putting very fast trains through evacuated tubes, my copy of the Usborne Book of the Future had this in seventies. Although Musk had a go at reviving it, the ideas Hyperloop has been based on have been around for ages.

#32In three years they developed the technology needed, more likely just ripped off the tech from Siemens on the Shanghai line.
Your sentiment is popular this days with the big propaganda we see but is there any hint that what you say is true, maybe they stole it from other company or maybe in a country with such a large population you will have a large number of smart people.
There are lawsuits involving the issue, as another comment reports. Jumping to ''big propaganda'' is unwarranted.
Re: China unveils 600 kph maglev train prototype
#33I’ve ridden on the Changsha Maglev, China’s first indigenous maglev and I was thoroughly unimpressed. The ride was rough and quite slow, nothing like their High Speed Rail which is world leading. I’m surprised they’d be able to develop world leading technology so quickly. But then again for areas of strategic interest we’ve seen China make similar bounds before. Makes me wonder how their Made in China 2025 efforts in…
Most of their "world leading" High Speed Rail, as you call it, is actually using Siemens Velaro D/E rolling stock — the same train used in Europe as "ICE" or for some of the Eurostar lines :)

#34I really wish we had high speed rail in Australia. I'd pick a 600km/h train over a plane any day.
High speed train works well in France (and it's just 300km/h) because the country is small. Australia is huge. And so is the US. This would make sense along coasts though but you wouldn't be able to cross the country from sea to sea in a few hours of course. What's good with trains is that you can hop in at the very last moment (when the bell rings, happened to me a couple times) and the train stops in the center of…
> it might become more interesting to dig long tunnels under cities for these trains rather than increasing the train's maximum speed.
That’s actually part of what the Stuttgart 21 project is doing, and why it’s so expensive (it’s not just a train station): https://en.wikipedia.org/wiki/Stuttgart_21
They’re building several massive tunnels below the city and through the surrounding mountains to put the entire station and all rails underground, which also improves travel times on the Paris—Vienna magistrale.
Being one of the first major projects of that kind in Germany, it has to deal with massive budget overruns and delays.

I will not bring up any names here. But I know there is a project between CRRC, Siemens and a university in Germany to transfer the knowledge from Siemens to China and update e.g. the controller algorithms
Edit: so all the rumors about stealing are not true. The knowledge is handed over

Thanks I did not know about that, would be good if this would have been added into the initial comment.

Also it doesn't really matter since the implementation is close to 20 years old, which means the patents should have expired anyway.
Patents are such a pain, I know someone that works in designing things for cars, and they need to actively avoid patents, things that are obvious and were patented you have to do not obvious things so you don't trip on them.

That's because DB is really bad. Everyone in Europe knows how bad DB is. It has nothing to do with high speed trains.
I didn’t know that. But then again, I only moved to Berlin late last year and I came from the UK, which is much much worse.

The lawsuit in the other comment doesn't involve Siemens though, hence "maybe they stole it from other company" might be more accurate.
