Robert Schwandl runs the superb Urban Rail site (here’s the page on Shanghai and a map of planned future extensions). Robert contacted me, asking

If you have access to recent and detailed info about the Line 2 extension to Hongqiao Airport and how it will meet line 10 and the mainline railway etc. that would be very appreciated as I get so many different versions.

If anyone has any authoritative information please let me know and I’ll pass it on.
