Paris RER B Evening Closures, 16 November to 11 December 2026: The Late Arrival Plan for CDG

The RER B, the train that carries most arrivals from Charles de Gaulle into Paris, closes on weekday evenings from Monday 16 November to Friday 11 December 2026. RATP engineering works shut the line from 22:45 between Châtelet Les Halles and the two northern branches, to Mitry Claye and to the airport station at CDG 2, with replacement buses covering the closed stretch.

Trains run as normal by day, so this is an evening problem with an evening answer: arrive earlier, or plan the road for a late landing. This post sets out when the line closes, what still runs, and what a late arrival at CDG should do instead.

This phase of the RATP engineering works runs from 16 November to 11 December 2026, following an earlier phase that ended on 10 November. On weekday evenings the line closes from 22:45 across the northern section: no trains run between Châtelet Les Halles and Mitry Claye, or between Châtelet Les Halles and CDG 2, until morning.

Replacement buses cover the closed stretch on closure evenings. A bus is slower than the train it replaces and it answers to road traffic, so a late arrival should allow real extra time for the bus, or skip it and take the road options priced below.

Trains run normally through the day and into the evening up to the closure, so a morning or afternoon arrival uses the standard plan. Trains south of Châtelet Les Halles sit outside the closed section, and Orly is not on the RER B at all: the metro Line 14 extension serves it straight into the center, untouched by these works.

Check the RATP plan for your exact evening before you fly: the pattern as announced is weekday evenings.

CDG sits 25 km northeast of the center, with three terminals: 1, 2, split into 2A to 2G, and 3. RER B trains leave from the Terminal 2 station; from Terminals 1 and 3, ride the free CDGVAL shuttle to that station first. On a closure evening, that station is where the train plan ends, so the real choice is made before you land: an earlier train, the replacement bus, or the road.

Every option, priced and compared, sits in our CDG to Paris transfer guide. The RoissyBus airport coach was discontinued in March 2026, so there is no coach to fall back on; after the last trains, night buses N143 and N144 cover the CDG route, or the flat fare taxi runs at the same price all night.

The Splurge pick is Hôtel Lutetia, the Left Bank grand dame on Boulevard Raspail in Saint-Germain, with a jazz bar and a spa. The Sweet spot pick is Hôtel Malte Astotel, a cheerful, well-run hotel on Rue de Richelieu, a short walk from the Opéra and the Louvre. The Budget pick is Grand Hotel Leveque, a small three-star on the Rue Cler market street, four minutes from the Champ de Mars. On a closure evening the bank matters to the taxi fare: a Right Bank address pays the €56 flat fare, a Left Bank address €65.

Inside Paris, the works change nothing by day. A single t+ ticket is €2.50 across metro, bus and tram, loaded onto a Navigo Easy card (€2 at any station machine) or straight into your phone. The metro runs about 5:30 am to 12:45 am, and to about 1:45 am on Fridays and Saturdays; after that, the Noctilien night bus network takes over on the same tickets.

Sort the ticket while the day service runs: load t+ tickets onto a Navigo Easy card or your phone at the airport station machines, and the closure stops being a midnight problem. Cards work almost everywhere in Paris, including the metro gates. Keep €20 to €30 in cash for markets and small boulangeries, use bank ATMs, and always pay in euros rather than accepting a conversion offer.

Get connected on landing. The guide eSIM pick is Airalo, online as the plane taxis in, which is how you check the RATP evening plan on the day itself. Then eat something Parisian: a still-warm croissant and a café crème at a café terrace. And book Louvre and Eiffel Tower tickets before you fly; the guide is blunt that it is the difference between walking in and queuing for two hours.

Four weeks of evening closures are easy to plan around: days are normal, late evenings run by road. Browse the events calendar for what else is on in Paris, and use plan your trip to line up the rest.
