The headline should point out the train is in a vacuum tunnel.

It’s the same fundamental idea behind Hyperloop One and some of the other Hyperloop-related efforts, although of course the vacuum train concept has been around for a lot longer than since Elon Musk popularized it (And got a bunch of flak for doing so...).

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…

> I hate the fact that an autocratic and repulsive Government The Chinese government is much more autocratic yet it obviously does a much better job in building infrastructure The problem with the US government is lobbyism. It does not work for itself, it does not work for the people, it works for big corporations and lawyers.

I also think that the people with influence, money and power have created a parallel world that almost has no overlap with the world most other people live in. They live in different areas, go to different schools, have different doctors or can afford the billing insanity in health care, have different career opportunities, don’t use the same air travel, have their incomes rise all the time. They probably really think that things are going great so why invest in or improve infrastructure and pay taxes?

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 nowh…

Rode it last year and it was fine. But i’m used to rail high-speed trains, so maybe that’s why i found it perfectly quiet and safe.

Another reason could be that it wasn’t the time of the day when it goes up to max speed ( it only reaches 400km/h on certain time of the day, some days only. other time it’s just 350 or something like that)

A train at M0.8 near ground level? The very first derailing/crash/etc will demonstrate quite well why this is a poor idea. Planes are quite far from anything easily damageable when they go this fast.

It’s in a vacuum tunnel. Basically like the Hyperloop One idea.

Earlier quoted context omitted.

> Jerry Brown tried to build the CA bullet train 4 decades ago. Amusing to me he did the Rip Van Winkle and popped up as Governor again after 30 years. In office he pushed hard to get CHSR built. Every time California's high speed rails come up on HN it's obvious that everyone here hates the idea. So the US is getting what it's collectively asking for and deserves here.

> Every time California's high speed rails come up on HN it's obvious that everyone here hates the idea California's major cities are almost in a line along the coast. That's the route that makes sense. California's HSR instead took a tour through the Central Valley's farming communities, taking a slam dunk pitch for linking San Francisco and San Diego via L.A. and turning it into a carcass.

Being along the coast also makes offshore supersonic flight possible. With a good aircraft, San Diego to Seattle should be about an hour.

I think there are two factors at play here. 1) We have the curse of being first. Our cities are old so our infrastructure is old. 2) We can't just say, "Your land is ours, get the fuck out, construction begins in one week" They can also cut corners on safety and pollution. The ends always justify the means.

If either of these things were actually the factors blocking high speed rail in the US, Europe wouldn’t have trains either. Eminent domain exists, and US infrastructure only feels old because we never spend money on it.

That's not exactly accurate. Western Europe installed its high-speed rail decades ago. They could not do it today. The US also could have done it in the 1960s or 1970s and made a disastrous decision not to.

You can see proof of that in the fact that Western Europe is barely maintaining its infrastructure properly today. Their spending on such has frequently fallen below US spending levels as a share of GDP.

That's even while having the ability to raise incredibly cheap - often negative yield - debt. Germany refuses to spend and it is starting to badly need infrastructure spending.

EU infrastructure spending as a share of GDP is at 1.8% - 1.9%. The US is at 2.3% - 2.5%. In Greece it's 1.1% (it used to be over 2%). Italy is seeing a similar problem right now as its infrastructure crumbles and they have to fight over spending rules constantly.

From the World Economic Forum's competitiveness report looking at 1998-2017 infrastructure spending and results:

EU and Eurozone spending on infrastructure has widely been below proper maintenance levels since the great recession a decade ago. The EU as a whole needs to spend a lot just to catch up to where it should have been right now with its basic infrastructure.

They aren't doing that, and they would build high-speed rail today? There is good reason to be skeptical of that premise.

"Europe’s spending on infrastructure at ‘chronic’ low level"

"Spending at 20-year low threatens region’s prosperity, EIB report warns"

"According to Statista, the percentage of GDP spent on infrastructure for UK, France and Germany ranged between 2% and 2.2% in 2013 marginally below USA who has been spending 2.4%."

Note: it's not good to be marginally below the US on infrastructure spending in any regard.

"Investment in infrastructure in the EU is today at 1.8% of GDP, according to the EIB Investment Report 2018. This is 20% below pre-crisis levels"

All the more fun to be had when it cracks/is terrorist-attacked/is subject to an earthquake.

Hearing this make me quite proud of the UK. Even though we have old Victorian-era infrastructure we still manage to run a decent intercity train system that can get you from Scotland to London in 4 hours or so. Much more pleasant than travelling by plane without the hassle of airport security.

The US doesn’t really have problems cutting corners when it comes to safety and pollution as well. For safety, look at the standard US power outlet and compare its safety with practically any other outlet in the world, of which all of them are considerably safer (albeit at the expense of being more complex and/or larger). For pollution, look at the current US Government actions.

I never understood this argument. The same vulnerability exists with regular high speed rail. In fact... Since it’s protected by a thick steel tube, it’s harder to do that than with a regular Maglev. Leaks take much longer to depressurize a vacuum than you might think and would help slow the vehicle down.
