Japan's L-Zero Maglev Train Reaches 310 mph In Trials 174
coolnumbr12 writes with this excerpt from IBTimes: "Japan's magnetic-levitation train is still more than decade away from completion, but the L-Zero recently proved that it really is the world's fastest train. On a 15-mile stretch of test track, the L-Zero reached speeds of 310 miles per hour. After the successful trials, Central Japan Railway Co. is going ahead with a 5.1 trillion yen ($52 billion) plan to build a 177-mile maglev line between Tokyo and Nagoya. CJR says the trip will take just 40 minutes on the L-Zero." There are other fast trains in the world, but the L-Zero edges out the others on this list.
A me too case? (Score:3, Interesting)
If every kilometer of it's tracks is about as costly as the German's maglev, what is the economic justification? China balked at the cost of a Shanghai-Beijing maglev line and built a wheeled system instead. And nobody has built a maglev after the Shanghai's airport to city center line.
Earthquakes? (Score:4, Interesting)
What are they using to protect the track against earthquakes? I'd hate to be speeding along at those speeds and have the track shift/vanish from under me.. or even the "mag" suddenly cut out for that matter.

The French TGV steel-wheel record holder was a heavily-modified racecar version of their regular 300km/h trainsets, running higher voltages and damaging track and overhead as it reached its peak speed (pictures of the TGV trainset setting the record show a cloud of track ballast being sucked up behind it). The maglev record was taken by a regular test carset with some modifications and did not damage the track which is regularly operated at 500km/h plus anyway. The maglev holds another speed record TGV and other trains can't even get close to, the passing speed record of 1026km/h when they ran two maglevs past each other on adjacent tracks at over 500km/h.
