They were invented decades ago.

They have fewer moving parts than wheelbois.

They require less maintenance.

There’s obviously some bottleneck in expanding maglev technology, but what is it?

    What kind of benefits are there to maglev trains that are not cost related?

        Then it’s good that we don’t have them, isn’t it? Kool_Newt’s post implies that it’s due to a failing of capitalism, but this sounds like a win to me. I’d rather my money go towards food and housing than a faster or more comfortable experience doing something I rarely need.

          One of the most common flights is US west coast to east coast. Normal high speed rail can’t do this in a reasonable time frame. We need something faster if we want to get reduce those flights.

          One of the features of capitalism is externalizing the costs, especially of pollution.

            Ah, that makes sense. So maglev is overall cheaper but still less profitable because the costs are paid where they’re incurred.

              Cheaper than flights? You’d have to do the math on it. We may have to accept that some things like travel will be expensive. But right now it’s not feasible Wrt to time to take a train or even HSR coast to coast.

          Sure, but if it lessens the impact on the climate from air travel and vehicles, then it’s a good thing. Especially if they can become reliable and convenient enough that people don’t need to have their own vehicles to drive everywhere.

                Thanks. So it basically comes down to externalizing costs again. Those who build the trains don’t see most of the profits or the costs that come with it, so they optimize for the parts that they do see.

                Regarding food, I as an individual need to eat every day, and I need to pay for that food. I’m not going to just not buy food because I’ll need it again tomorrow. It doesn’t matter if the government provides the food or I buy it myself, it’s still money that needs to be spent on it. One could argue that food security also leads to similar second/third order effects by freeing up that mental real estate dedicated to survival and allowing it to be used for positive contributions to the community, though I don’t have data to back this up so it’s just speculation. Similarly, if the rails are public and built using my tax money while providing me with no value, I would consider it to be wasteful as survival takes precedence over comfort. If it’s private and not profitable, then it means no one wants this for the price it takes to build and maintain, so it was a bad idea to have it in the first place. But either way, this is all moot because it’s a conclusion reached from incomplete information. I’m down for public spending on this if there are higher order effects that everyone benefits from.

          And how about the actual speeds they are used with? Another poster suggested the maintenance costs of traditional speeds skyrocket as speed increases, while maglev doesn’t really have a lot of stuff that wears down in the first place.

          I doubt conventional trains are regularly traveling at the speed record. Thats a poor way to compare the speeds of things.

      Better acceleration, steeper inclines, tighter curves at same speed, better ride quality and less wear. As someone has mentioned below, normal trains could go a lot faster than they do in practice, because the ride quality, wear and wind resistance get atrocious, and the tracks need to be exceptionally straight. Making a maglev go fast is more feasible, though you still have the wind resistance issue obviously.
