Hello,
In January I visited Beijing and Shanghai China for business. When we arrived at Shanghai airport we decided to take the magnetic levitation train from the airport to the business district. While waiting for the train it was interesting to see that there were no rails, just some flat plates. These trains float on magnetic forces and they can smoothly go fast. We achieved 300 km/hr (or 180 mph).
I took a bit of video to show what it looked, sounded, felt like. Unfortunately, I missed the instant when the train traveling the opposite direction and passing at the relative velocity of 600 km/hr. It was startling, and pretty damn cool.
