L'exploitation de la ligne prévoit que les trains en provenance de l'est auront leur terminus en gare de La Folie (sixteen trains par heure sur la base des cadences actuelles et hors extension de la branche E2 à Meaux) et ceux en provenance de l'ouest à Magenta ou à Rosa-Parks (6 trains par heure).
