Riding the World's Fastest Train @ 500 kph
angkor writes "Riding the world's fastest train @ 500 kph - some lucky people got a chance to ride on this experimental train. The Japan Times has the story." I like the part where the wheels retract as it starts picking up speed, with the train floating 10cm over the tracks. If only the California high-speed rail system was up and running.
The French TGV has been going at 515 kph several years ago (albeit it was not pulling regular cars). And that was with a regular train (no funny shit with the wheels, just a long straight railway)
