Which Shanghaï railway station ?

Dears Madams and Sirs,

I have bought a ticket to join SH to Suzhou with the train G7040.
It is labelled "SH-> Suzhou".
As there are several railway stations as well in SH as in Suzhou, I cannot identify which railway stations are concerned in both towns.
Could you please help me ?

Thanks in advance.
Best regards from a lost frenchie.
