Robotic High Speed Train that Looks like a Plane

A new high speed train being tested resembles more a plane. The new train doesn't use tracks and actually flies slightly above the ground.  See the link for videos.
A ground-effect vehicle takes advantage of this fast-moving air and uses some stubby little wings to fly just above the ground, like a maglev without the mag. This is a tricky thing to do, since you have to control the vehicle more like an airplane than a train, meaning that you have to deal with pitch, roll, and yaw and not just the throttle. A Japanese research group led by Yusuke Sugahara at Tohoku University has built robotic prototype of a free flying ground-effect vehicle [photo above] that they're using to test an autonomous three axis stabilization system

It seems as complex as french Aérotrain (if not more), which was sustended on an air cushion (much like an hovercraft). It achieved nice performance for its time, but was ultimately a failure due to the need of new dedicated railways and the expensive running costs (used aircraft turbines in later versions).

Dave - The interesting thing about this isn't that it uses propellers.. the interesting bit is the fact that it's flying, unlike the train in your video, which is, you know.. rolling.
