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.
Management is indeed a different issue from building. Germany builds (or at least used to build) passenger trains - Siemens worked in conjunction with Russian railway and underground to create trains currently running in and around Moscow.
But ask any German about the Bahn and you’ll see steam coming out of their noses.
