I had the opportunity to travel in one of the fastest trains in the world - the Shanghai Maglev. This was built in 2004 at a cost of 1.3 billion dollars and it connects the Pudong International Airport to the city. However, the technology did not make much economic sense and is only used by few tracks in China, Japan and in Korea. The trains could run as fast as 300 miles an hour and they do not even have wheels on them as they float on the track due to magnetic levitation. It was a cool thing to try while in China. Of course, we got a 20% discount on the ticket by showing our flight tickets to the counter.
