Buying the tech from Japan isn’t gonna solve the fact that you don’t even know how to manage a normal passenger rail line, buddy!
Also I know this is technically a Japanese news site reporting from their perspective, but the US is still seriously considering this on their end, just like how they’ve been considering it since Japan first introduced the SCMaglev prototype decades ago.
I wonder if it has something to do with surface exposure to magnetic fields. A very strong magnetic field, enough to levitate a train, zipping by you at the speed of said train, while not harmful to human biology unlike a lot of fear mongerers claim, can interfere with radio antennas and the navigation systems on ships and aircraft. The inside of the train is heavily shielded but I imagine it’s pretty much impossible to prevent it from escaping into the outside without containing the entire track in shielding.
