Paris Transit Works Cut Metro and RER Feb 9 to 15
Planned modernization works across Paris, France are reducing normal service on parts of the Metro, RER, Transilien, and connecting surface networks through February 15, 2026. Visitors are most affected when their itinerary depends on airport transfers, late night returns, or popular day trips that lean on a single corridor such as RER B to Paris Charles de Gaulle Airport (CDG) or RER C toward Versailles. The practical move is to treat rail as conditional during this window, check your exact line and time of day before you depart, and switch early to a simpler backup when the work window lands on your route.
The Paris transit works pattern matters because the disruption is not one citywide shutdown, it is a rolling set of line level work windows that can turn an itinerary that looks fine at midday into a broken connection after 10:00 p.m. or on a weekend segment closure.
Who Is Affected
Travelers using Paris Charles de Gaulle Airport (CDG) are a top exposure group on Saturday, February 14, 2026, and Sunday, February 15, 2026, when the RER B line operator says trains are scheduled to be interrupted in both directions between Gare du Nord and Aéroport Charles de Gaulle 2 TGV and Mitry Claye all day, with replacement buses planned. If your plan assumes a simple one seat ride to the terminals, the bus bridge changes the timing, the luggage handling friction, and the reliability of tight check in cutoffs.
Versailles day trippers are also exposed over the same weekend because Transilien's RER C work notice shows a full weekend interruption between Champ de Mars and Versailles Château Rive Gauche and Saint Quentin en Yvelines on February 14 and February 15, 2026. That is a classic tourist failure mode because it strands people on the wrong side of the river late in the day, or forces a longer, more complex alternative with extra walking and transfers.
Late night diners, theater goers, and anyone returning to hotels along Metro line 12 should plan around full line closures from 10:00 p.m. on Wednesday, February 11, Thursday, February 12, and Sunday, February 15, 2026, because RATP states there is no replacement shuttle. When there is no bus bridge, the real risk becomes last workable connections, not just slower travel.
Regional movers and travelers connecting through major stations, especially Gare de Lyon, should also expect added variability because RATP's RER D traffic page shows mid day works that interrupt trains between Corbeil Essonnes and Malesherbes from 1011 a.m. to 123 p.m. on weekdays through February 13, 2026, plus additional weekend and late night work items on other RER D segments. Even if you are not riding those exact branches, crowding and platform churn can propagate into station transfers, taxi queues, and missed departure windows for onward rail.
What Travelers Should Do
If you are traveling to or from CDG on February 14 or February 15, 2026, plan your airport segment as a two step chain, city to Gare du Nord, then the operator's replacement bus, and add more buffer than you normally would for luggage, queues, and traffic variability. If you have a long haul flight, a nonrefundable train, or separate tickets, the more robust choice is to pre price a taxi, rideshare, or car service and switch as soon as the rail plan requires a bus bridge, rather than discovering the surge at the curb.
Use a simple decision threshold for late nights: if your return trip depends on Metro line 12 after 10:00 p.m. on February 11, February 12, or February 15, 2026, reroute before you start the evening, because RATP notes there is no replacement shuttle and last connections across the network are easy to miss when one line drops out. In practice, that means choosing an alternate Metro corridor earlier in the night, or deciding that a taxi is the fixed cost of keeping the evening plan intact.
Over the next 24 to 72 hours, monitor the line specific work notices that match your exact station pair, not general headlines, because the same named line can be fine on one segment and closed on another. For Versailles, treat February 14 and February 15, 2026, as a re route day, since the RER C notice shows the Champ de Mars to Versailles Château Rive Gauche and Saint Quentin en Yvelines weekend interruption, and build extra time for transfers and navigation if you are not used to Paris interchanges.
Background
Planned works in the Paris region propagate through the travel system in layers. The first order effect is straightforward, a closed segment forces a detour, a replacement bus, or a different line. The second order ripple is what breaks trips, interchange stations concentrate more people into fewer corridors, which increases platform dwell, lengthens transfer walks, and raises the chance that a traveler misses the last workable train even when most of the network is still running. The third layer shows up in pricing and capacity, when rail is less direct, taxis and rideshares absorb demand spikes, and travelers who miss timed entry slots, tours, or onward trains are forced into rebooking decisions that can be more expensive than taking a road backup early.
