Maglev train, Shanghai, China
The magnetic levitation train demonstration line in Shanghai China is suffering from a huge marketing problem. Sure the train is blindingly fast and smooth. Sure it's a blast to ride on it has it banks steeply around the curves at speeds up to 430 km/h (it was going a mere 300 km/h during my ride.) the problem is that the demonstration line from the airport to Shanghai is 30 km long, so, even on the slow train I boarded, you're there in 6 minutes and hardly realize just how cool that is for your 50 RMB!
