Actually, I am toying with the idea to fly to Shanghai (instead of Hong Kong) once in my life just to be able to take the Transrapid... Can you tell me when those high-speed time slots happen?
For me, Hong Kong and especially its skyline was much more futuristic and fascinating. If you've never been there, go for it!
I also feel it's like the M&M test for quality and culture of a company or nation.
(in Montreal they also believe that heir trains are super smooth and quiet because of the rubber wheels, compared to steel train. I can not explain this belief.)
The experience of going so fast so close to the ground is quite maginficent. I was wondering why the cars 'stop' on the nearby motorway.
The German Wikipedia says that there are two 45 minute slots a day, but not when exactly. Maybe their web site tells it? I could find the information after a cursory look.
