I suppose so? The Shanghai maglev train [2] might be the only high-speed maglev in operation [3]. The train has a cruising speed of 431 km/h, but averages 250 km/h in actual operation — covering 30 km in 8 minutes with no stops in the middle.

[3]: Maglevs in Beijing, Changsha, Incheon, and Aichi Prefecture all operate at ~100 km/h or less.
