Since when do the Chinese build stations outside of the city? I can pick from any 4 stations all centrally located in Shanghai, and get off the train after 4 hours in the heart of Beijing and be in my hotel in 15 minutes. The same goes for any city. Chinese build airports outside of the city. If I would do the same trip with flights, I need travel 1 hour to the airport, be there 1 hour before, 2 hour flight, land 1 hour outside of Beijing. That's 5 hours if all goes smooth. This is why high speed rail is the preferred option to travel. Especially if you can afford business class.
