Well yes, I do live near a train station. it's a 15 minute walk away from my home.
The lines though? There are plenty! We've got the Paris Nord to Villiers-le-Bel line, which diverges into multiple lines which are, but not limited to:
-Ligne Nouvelle 1 (A high speed line used by Eurostar trains to London, Thalys trains to Brussels/Amsterdam/Koln and TGV trains going to Valenciennes, or Lille)
-Villiers-le-Bel to Creil line, with suburban trains going towards Orry-la-Ville and Creil, as well as Intercity and regional trains linking Paris to northern France cities like Amiens, Compiègne etc...)
After that, we've got the Paris to Pontoise line, the Paris to Luzarches line and the Paris to Persan-Beaumont line, all used by suburban trains. Regional trains usually pass through the Paris to Persan-Beaumont line to head north, towards Beauvais as well.
