We have a flight in the early morning 1.20 am, and I know Maglev operation ends by 21.10Pm everyday.

We wish to travel at the fastest speed of 430km/hr; instead of going for no reason, I would like to know if there is any attraction the other side when we go by this train and come back.?
Or should I just make a trip to nowhere to just experience the same ?
Looking forward for your replies !
