>>1343047Germany did it 20 years ago. Pic related is the Transrapid maglev on the test track in Emsland, Germany. A commercial implementation of this system has been up and running in Shanghai since 2002. The Transrapid was designed for 311 mph, but has since been overruled by the Japanese SCMaglev which reached 375 mph during test runs (5 mph faster than this theoretical system you're talking about).
I don't wanna fuel /pol/tards here, but I find it extremely unlikely that one of us railway /n/erds would go "holy shit" over something as uninteresting as this. Over the last months, I noticed a lot of these overly excited posts that seemed just a bit off, and funnily enough they were all about something in China. Posting on an Anonymous image board with 100 users wouldn't be the silliest thing the Chinese propaganda department has done. Tiananmen square Winnie the Pooh.
