    Meanwhile in Canada we’re still using diesel trains, but don’t worry! In another decade or so they will be scheduled more frequently!

        Just give me 300kph trains from Windsor to Montreal. Get that stretch, then we can talk about everywhere else. Most of the infrastructure, and population is on that corridor. It would literally transform the country… But it would require government with vision

        Well we can’t make trains affordable and convenient how else would we make local domestics flights cost more than international flights across a damn ocean?

        Such capitalist efficiency!

    See what is possible when you arn’t focusing your economy on blowing the rest of the world up for manufactured scarcity and exploitation?

    This is the type of leaps and bounds I was expecting from the US coming out of high school 20 some odd years ago.

      during the cold war they told us that they wished they could spend money on schools and healthcare, but those darn Soviets would overrun us if we didn’t spend it all on guns and bombs. “peace dividend” my ass

        Every gun that is made, every warship launched, every rocket fired signifies—in the final sense—a theft from those who hunger and are not fed, those who are cold and are not clothed.

        This world in arms is not spending money alone.

        It is spending the sweat of its laborers, the genius of its scientists, the hopes of its children.

        The cost of one modern heavy bomber is this: a modern brick school in more than thirty cities.

        It is: two electric power plants, each serving a town of sixty thousand population.

        It is: two fine, fully equipped hospitals.

        It is: some fifty miles of concrete highway.

        We pay for a single fighter plane with a half million bushels of wheat.

        We pay for a single destroyer with new homes that could have housed more than eight thousand people.

        This—I repeat—is the best way of life to be found on the road the world has been taking.

        This is not a way of life at all in any true sense. Under the cloud of threatening war, it is humanity hanging from a cross of iron.

        Eisenhower

        Would be such a good speech over all of he didn’t spend the bit right before this blaming the mistrustful Soviets for not just like taking their word that “the free nations” 🙄 are not aggressive

        Japanese anti semites believe that the reason Jews controlled the world was because they invested in infrastructure and transportation. And they wanted to usurp this supposed Jewish cabal with a Japanese cabal. I don’t know if this ideology influenced their decision to go ham on trains and other tech, but lmao

      Except they haven’t actually demonstrated anything, there were a bunch of startups and others in the west who have done this same ‘demonstration’ before concluding (rightly) that it wasn’t worth pursuing. Socialism doesn’t change physics, it’s still a stupid idea. Just because some group in China is now on the grift doesn’t change that fact.

    Faster than airplanes (which are crazy fast, although we are accustomed to them) and wayyyy lower on energy-use.

      Yeah, this is strictly superior to air travel. Also, just from sheer convenience perspective, these could have stations right in the city, so you don’t have to go to the airport, wait to check in, etc. for like an hour before you even get moving. Just hop on and hop off in a different city.

      People have been blinded by a level of understandable Elon hate until China started working on it. The talking point was that it would be a larger evacuated space than the largest vacuum chamber ever built by NASA and therefore impossible, not considering that a very long tube is not comparable to a huge dome. You dunked on me before but I am vindicated!

          I don’t think that’s necessarily a bit. I’m not a train watcher guy but I can relate from the bicycle sphere.

          Bicycle drivetrain parts were an oligarchy at best, a duopoly between SRAM and Shimano at worst for the past 20 years or so - discounting the really high end or the oddball stuff with nigh 0 market share. Everything from china was obviously decried as a cheap shitty knockoff of those parts - having no experience with any of it, I can’t tell you how true it was.

          But more and more I see people using shit ordered of AliExpress, Temu and such because prices have dropped so much even if you have to buy two because the QA is kind of ass you still come out ahead. Fuck I see people recommending carbon frames by now and those fail fucking catastrophically if they fail. Real vibe shift going on there.

    The concept of a transportation system in a low-pressure tube was proposed in 2013 by Elon Musk, who called it Hyperloop, but his company focusing on developing the system - Hyperloop One - was shut down at the end of 2023, Reuters has reported.

    The official website of UK-based Virgin showed that its Virgin Hyperloop made its first successful passenger test in 2020.

      I mean it’s not like China is pursuing it in favor of proven HSR. They already built out a really efficient rail system all across the country, so now they have room to experiment with this sort of tech.

    Most** Chinese HSR is already past the point where you can’t make it go any faster (without subjecting passengers to uncomfortable G-forces), but this is cool regardless.

        Put down your physics textbook and turn your civil engineering textbook to page 420.

        I am talking acceleration - specifically, accelerating from a station, and decelerating as you arrive at a station. Those two activities create G-forces, and there is a maximum number of G’s you can subject general passengers to, and when stations are close to each other - or the path between them isn’t a straight shot - then your passenger G tolerance limits how high of a top speed you can reach before you have to start braking. Going faster requires your stations to be further apart, it requires the grade to be more gradual, and it requires the route to be more direct.

        Subways stop every couple of blocks. It doesn’t matter how big of an engine you put on a subway car, they will never go faster than they do now. Regional rail can be a little faster, but it still has to stop every couple of miles, which means even if you put a bullet train on those tracks it simply can’t get up to speed. Rail between cities is pretty much the only place you can put HSR, and the currently-existing HSR track isn’t a candidate for maglev track because it’s not precise enough, straight enough, and in many cases long enough for a maglev train to get up to its top speed and actually save time over the HSR that already exists.

          The way you avoid having high G-forces is by accelerating over a longer period of time. These kinds of trains would be used for fast transit between cities that are many hundreds of kilometres apart, not for short hops like a subway. This is precisely why China has different types of trains for different situations.
