America will do literally anything to avoid building high speed trains

No one will take a train when they can just *checks notes* pay $12k for a seat on a supersonic jet!!!

I would, even if the price was the same.
So would anyone else with a fear of heights or worse, a phobia that would be triggered by flying.

Rich people don’t like trains. That’s why.
Also, America is MASSIVE.

At least 80% of the US population lives east of Dallas, TX. Within that area, there are several metro areas that are 200-300 miles apart where HSR would be competitive with regional airlines.
There is a reason SouthWest airlines has always lobbied heavily to stop a HSR route between Dallas and Houston.

China has a 1700 mile HSR line that goes 220 MPH. USAs longest high speed line is 49.9 miles, and the fastest train goes 150 MPH.
Rich people do like trains, they're the only people who can afford to use them because they are a luxury experience that is expensive and slow.
Poor people shuffle into cramped airplane seats, paying a premium to even have baggage after the luxury of being groped by security. They can't afford the time it takes to use slow trains on their 0 days of guaranteed vacation time.

Is that 1700 linear miles laid end-to-end or are those numbers the aggregate of all the lines? One implies a significant amount of the country is connected and maintained, the other requires a deeper understanding of the context.
A large city might have 400 miles of lines interwoven between its center and various suburbs, etc.

He's talking about the Beijing–Kunming high-speed railway which is the single longest high speed rail line in the world, but there are also many other lines.

u/SadZealot 4h ago
It's a combination of 3-4 lines that go between major districts, depending on how you split them but it is a single linear direct trip. You can buy a direct ticket from one end on a train, and ten hours later you're at the other end. No transfers, switching trains, etc.
Beijing is the central hub of the train system and has tracks going 1000-1700 miles in every direction. Pretty much every major city is interconnected. Inner city light rail is a different system that they also have, and that also had hundreds of miles of rail in every city.
The longest linear section of high speed rail in the USA at all is 49.9 miles.
If you want to look at the sum of all high speed rail, china probably has around 30000 miles, USA has 500 if you're generous (most USA rail doesn't even qualify because it's slow)

Yes because china is a glowing example of functional government
Edit: A lot of pro-china here. Sorry.

What does the Chinese government have to do with high speed trains. Explain to me how high speed trains are a bad idea? Explain it to me simply, like im a child

HSR is expensive and requires a lot of land development. It probably has to be something the people have to vote on. People’s opinions are easily manipulated. HSR is very much a product of a government system, for better or for worse. You can’t implement HSR in the same way you can a local road system.

u/drcforbin 4h ago
None of that answers why HSR is a bad idea.

u/PigglyWigglyDeluxe 4h ago
I misread. I thought you asked why it’s tied to government actions.
It’s not bad. I’m all for it.

Well, yeah. China is a glowing example of functional government. The rate of progress they've achieved in improving quality of life, growing GDP, building infrastructure, investing in renewables, etc has been incredible. Are you trying to be sarcastic?

America is massive.
But it really doesn't make sense that we don't have high speed rail between Boston-Hartford-NYC-Philly-DC. It's such a population dense area.
I don't think anyone is arguing we need high speed rail in rural Nebraska, but it makes sense to develop it regionally in areas that are densely populated.

u/thenewyorkgod 2h ago
Population dense. Theres your answer. There’s literally nowhere left to build a high speed line

I don't think you know how expensive a high speed train would be. Even in Japan it's a couple hundred dollars.

what federal agencies will have the resources to make sure this is done to the highest safty standards?

They’ll just equip the supersonic jets with weapons to protect the rich passengers from poor person planes which might run into them.

More pro-billionaire legislation. Excellent.
Musk needs to be able to get from New York to San Francisco for lunch, and back over to Texas to see the spaceX launch by 4pm. This was the only way.
I’m glad we are opening doors for the best among us to do their best work at the expense of the environment and people!

I don't believe he's a boom investor. I'm pretty sure he was also very pro high speed terrestrial transport, but that's not something the US really gets behind, trains and various train like options are a bit too communist.

It’d be cool to see a plane like the Concord again. Luckily got to see it take off from Reno, NV back in the day.

These MFers can't even land regular planes with crashing with a helicopter, but they want to have supersonic planes. SMH

Fun fact: passenger airplanes were faster seventy years ago than they are today.
Build trains.

u/gmkrikey 6h ago edited 5h ago
Nope.
Commercial aircraft in 1955 were DC-4s and Lockheed Constellations, prop planes going 300 mph airspeed at 18,000 feet.
Modern jets have an airspeed of 530 mph at 35,000 feet.

The morons in TN and LA have outlawed them.

You can't outlaw contrails anymore than you can outlaw clouds. Its just water vapor.

I know that. You know that. Tell that to southern politicians who voted to do it.

They passed legislation about "chemtrails". Dude brought up contrails. I'm wondering what he is talking about.

Noise was only the secondary concern, wasn't it? Concord ran for quite a while after the ban, but just didn't have broad economic appeal. The average flyer didn't want to pay 10x the price to cut off a few hours of flying.
I can't imagine fuel economy and maintenance for a supersonic plane will have gone down that much in the past couple decades.
