Get ready for some high speed transport action – Chinese researchers are currently developing a vacuum maglev train that they believe will run at speeds up to 620 miles per hour. This just a few years after Japan announced their — then totally awe inspiring — plans for a maglev train that would run at 310 mph. The train will run on magnetic levitation tracks built into vacuum tubes underground and will be sucked along at an average speed of almost 400 miles per hour. What’s the cost for this zippy technology, you ask? A mere $2.95 million more than the current high speed rail for each kilometer of track.
