Well, who to believe?
Shanghai Metro website and Google Maps are some way apart in their calculations.
I will go for the Metro website.
Let's head to the Shanghai Circuit. The race might be over but it's still Saturday in game time. So let's get ourselves a spot staked out in readiness.
We leave Xujiahui at 2036 and taking a Line 11 train we reach Shanghai Circuit station at 2112 on Saturday night.
One thing I will note here, the timetables and journey planner info all say you can take a Line 11 train from Xujiahui to Shanghai Circuit direct. However only the map of the system that is shown on the Shanghai Metro website shows this. Must be a very recent extension. Update - No 2013, yet most Maps don't show it. Ha, that's China - growing so fast the Metro maps can't keep up!
