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?
The Shanghai airport transrapid is surprisingly loud and rumbly, kind of like a roller coaster with its rubber wheels. Or like the Montreal Metro.
(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 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.
