Not bad, it's not completely clear from the article but checking wikipedia L0 should be a "production" maglev, similar to Shanghai's Transrapid (except Transrapid's maximum operating speed is 410km/h. It did reach 501km/h in early test runs but doesn't reach that on scheduled traffic).

It's good to see that tech finally get in production (Japan's maglev demonstrators first breached 500km/h in 1979).

FWIW, if all goes well the L0 should be used in the (planned) Chuo-Shinkansen line going straight from Tokyo to Osaka through Nagoya in 67mn: http://en.wikipedia.org/wiki/Chuo_Shinkansen (the fastest runs on the Tōkaidō Shinkansen currently take 2h25)
