An extensive redesign has been carried out until 2006 by AREP (Paris), ECADI (Shanghai) and MaP3 (structural engineer - Paris), making the new station the world's first circular railway station. With the reopening, two minor Shanghai railway stations have been closed: Shanghai West in Putuo District and Meilong station near Jinjiang Park. All railway connections of these stations have been moved to Shanghai South station, and according to estimates, up to 40% of passengers of Shanghai station will be diverted to the new station.
