Hmm, 7500 miles between Beijing and Shanghai. 11 hour trip now comes to 681mph, no slouch that train. And after the high speed line is completed, 5 hours or 1500mph, now that's fast.
Need to tighten up the editing guys.
Try 750 miles for the trip and you get a much more believable number. (68mph avg velocity) 7500 is almost the diameter of the earth.
