Suggestion on what to do in Shanghai, China for the day??

[joybook]

I was certainly not aware that the train speed varies depending on the time of day but in response to the previous post I note that the time we were doing 431kph was 10.05am. On the display in the carriage the time of day is shown as well as the speed of the train. I will say though that from memory we only went the top speed of 431kph for about one minute or so.:)

Sounds like mid-morning's a better time!

 

I did a search and found reference to differing speeds, but couldn't fine a rule when.

 

However, I travelled in the evening (due to flight times) so that fits in with the above.
