Magnetic Levitation can exceed this speed limit. From the FTA:
> a Japanese maglev had set a speed record at 581 km/h. The French managers considered it pointless as well as prudent to force the experiment to exceed that speed, as they could have entered a kind of “international race” that they did not have much chance of winning. Time would prove them right: in 2015, another L0 series maglev reached 603 km/h on the Yamanashi test line.
Chinese maglev seems to run at 431 km/h and brings in losses of more than 1 billion RMBs[1]. So these trains may not be economical.
