As fast as a jetliner, and way more efficient. Can be powered without fossil fuels. This is the future. Where is America on HSR?

https://www.youtube.com/watch?v=0JDoll8OEFE Please, I urge you to watch this. It explains thoroughly why the situation for railroads is very different between China and America. tl;dw: America is more spread out, has better airline control, and less of a political incentive to expand public transport, than China.

Isn't the density a bad excuse since you can add the infrastructure only in regions with large density like California?

Why not debate the article, there are many anti-China articles on the first page too, like in this case is very interesting to see what the technical issues are and how can be work around them.

Sure, but pro-China shills should not be allowed to post on HN, period. It's in violation of the policies. Dang, can you look into this?

Which one in particular?

I found one that applies to you.

Has anyone else here ridden the maglev in Shanghai out of the airport? My 2c is that it was awesomely fast and convenient.

BUT, I was a little unnerved by how much the train jostled at some points. It was like the supports for the track had sunk in some places leading to the tracks no longer being aligned.

Not really informed by anything concrete, but I think there’s a disaster waiting to happen there. China has nowhere near the safety culture I’m used to in the states.

Now the conventional cars of the Shanghai metro? I really with the west coast of the US had infrastructure like that!

Hasn't the last 50 years of attempting these shown that they're uneconomic in the extreme, and probably will continue to be even if China puts its admittedly heavily state-subsidized rail-building prowess behind it?

They are amazing. There is one in Shanghai that connects the airport to the city. Imagine a ride from SFO to Salesforce tower in 7 minutes.

The Shanghai Airport Maglev was built by a German company trying to prove the concept for longer distance maglev construction. It was a failure; it was way too expensive and not meaningfully faster than conventional high speed rail.

I see two posts that can be construed as pro-China within the last year (This being one of them).

I count at least three. No way this isn't an shill account.

Three posts about a large country constitutes a "shill account"? How does one even define "shill account"? Does the same standard apply to posts about USA or companies?

So, as someone that lived in New York for 6 years and California for 6 years, stories like this are incredibly depressing. The US is the world's largest economy and should be the shining example of amazing infrastructure, high-tech, green cities, and forward thinking policies. California is an especially egregious example in terms of infrastructure investment: If California was a country it would be the world's fifth…

As a commenter stated below: Be careful comparing a system which can simply take the land and labor it wants to one in which people have rights. China also has the lowest organ recipient lists, maybe we should try to emulate that too: https://www.businessinsider.com/china-harvesting-organs-of-u...

That't not an excuse. You can build infrastructure without violating peoples rights. It may be more difficult but definitely doable. Look at Japan or Europe. This is a political issue based on a missing long term agenda.

dang, can we ban this account? It looks very suspicous (posting a lot of pro-China stuff, username, etc.)

That is going to be the last day I use HN. I think this comment above just shows the intolerance of some people here who are yelling for moderation and unwilling to debate anything that is slightly against their worldview.

I said the same thing years ago yet I keep coming back for the helpful information. I simply ignore posts like these 99% of the time.

Other, and actually main, reason is that good public transport decreases cost of land, it is basically designed to do so: it makes more places liveable/jobs reachable, so there is effectively more land for the same amount of people. So everyone will vote against or they lose their pensions. Want to fix this? Sure, easy, just scrap the democracy and just don't ask people, send those who object, to "re-education" camps…

Just a heads-up: This person has posted at least 12 pro-China comments in the past year by my count. Extremely suspicious.

I strongly disagreed with them on this particular thread, but I don't get why having pro-China views should be automatically considered "extremely suspicious"?

That use case is perfect for Maglev. Essentially replace Caltrain.

This sounds like more of a hyperloop type thing than a traditional maglev train: > if the concept of maglev trains swinging inside a vacuum tube can be put into practice That means this will also have all the same problems as a hyperloop.

Maybe they plan a hybrid, so the same train will travel on regular and tunneled tracks.

Though I was expecting that new materials and design could reduce the air friction even more in the future.
