News monitoringRER C — Pontoise / Versailles-Château–Rive Gauche ↔ Massy–Palaiseau / Dourdan / Saint-Martin-d'Étampes
The RER C is entirely SNCF-operated and has the most branches of any RER line, running along the Left Bank past the Eiffel Tower, Musée d'Orsay and Invalides before splintering to Versailles, Dourdan and Étampes. An SNCF strike therefore hits it directly, and outer branches are usually suspended before the central section is.
What a strike means on this line
The RER C is operated by SNCF, so it is affected by SNCF strike notices. On a strike day expect outer branches to be suspended first, with a reduced service maintained on the central section.
