is the C train from St Michel to Versailles operating again?

On weekends (Saturdays/Sundays) starting Sept. 16 through October 8, no RER C trains will be operating between Austerlitz and Invalides inside Paris (which would go onto Versailles).  To go from Paris to Versailles you would need to take the RER C from Invalides station on the western side of central Paris (or stations further west: Pont de l'Alma, Champ de Mars or Javel).
 
Paris-Versailles trains on Monday-Friday will still be operating as normal.
