On trains the cars have to be connected to each other. The structure has to bear the load of all of them at once. Not the case with hyperloop.


The reason we have to run long, heavy trains is it's unsafe to run two passenger capsules at 300kph a minute apart. I find it hard to believe regulations will permit that even when they're in a tube.


It's totally implausible that that's the primary factor.


Why? You've given no explanation.


Nor has jim-greer.
