Mag Lev in the wild

All this time, I thought mag lev trains were dead, but it looks like there's one in the wild (or almost). A 40-mile link between Shanhai and its new airport will be serviced by the mag lev train. While that's cool and all, I kinda wish they were going a little further — maybe a train between Shanghai and Beijing, for example. 40 miles doesn't seem like enough distance to really get up to speed and appreciate the ride. Imagine going 300 mph in a train! I hope someday we get them here in the US. It'll make the Acela look like a rinky-dink freight train.
