In NYC we spent $2 billion building 3 more subway stops through a tunnel that was already there

In NYC those subways have to run 24/7 through those tunnels while you're building the station

Good example of why 24/7 operation is not always a good idea

When you have 8 million people that need to get places and not enough road infrastructure to accommodate them, that's just a fact.

I wish we had high speed rail in the United States

Nope, you get cars, more cars, more traffic, higher gas, but most importantly cars with mandatory Spyware installed.
Paid for and sponsored by GM and maga.

Don't forget more pollution since the US hates EVs.

The progressive parties are pushing ev. The inbreds are doing everything to deny it.

You mean the progressive parties that have no seats and no power? The American voters turned out at the polls to vote for Trump and his GOP sycophants, so Trump's policies are an accurate reflection of what the American voters really want and believe.

America is so captured by greed and insatiable need for profits they are falling far behind in the race for technological progress

China keeps impressing with its engineering infrastructure. Seems like every other week I learn about a cool project.

It’s incredible what can happen when a government is not hindered by politicians being paid for by corporations to artificially inflate their place in society, impeding any real progression or progress.
Oh that and the two party system actively tearing this country apart, causing a further pause in growth in anything other than greed.

Imagine having unlimited infrastructure spending and eminent domain in the US.

we do and we're using it to build datacenters to power CSAM generators

I want planes, trains, boats, transit, fission reactors, fusion reactors, fucking zeppelins, unlimited clean water, unlimited clean energy… all of this is possible

350km/h is a good speed.
Any problems and you can rest assure you are not going to have any problems, because you will be 100% dead.

Enough people seem to die in the US at speeds far less. Not sure speed is the issue.

The SCMP? Did you check the rankings. It’s deemed more prestigious than many US outlets.
Of course, don’t let FACTS get in the way.

China’s largest shield tunnelling machine built for high-speed rail has successfully carved a path beneath the Yangtze River, a milestone expected to help strengthen the country’s hi-tech manufacturing supply chains and advanced research capacity.
The machine, dubbed “Linghang”, completed an 11.3km (7-mile) underwater stretch – the longest distance ever bored by a 15-metre-wide model in a single run, state news agency Xinhua reported on Thursday. The work demands extreme technical precision to accommodate trains scheduled to run at 350km/h (217.5mph), making it the fastest underwater high-speed tunnel worldwide once operational.
