Where is the Shanghai Suburban Railway platform located in Pudong AIrport (PVG)?

Where is the Suburban Railway platform located? I found the Metro and Malev platforms, but not the Suburban Railway Link.
And does the Suburban Railway line go from Pudong PVG to Hongqiao Railway Station?
Hongqiao Airport and Hongqiao Railway Station share 1 station or is the Station 1 stop past Hongqiao Airport ?

Thank you
