Just as the capital welcomes thousands of delegates for the Choose France summit and end-of-year trade fairs, Île-de-France Mobilités and SNCF Réseau have scheduled a dense programme of night-time engineering works across the RER, Transilien and Metro networks. An operational bulletin issued this morning details partial closures on every RER line, a full shutdown of Metro line 14 on Saturday 23 November until 14:00, and evening cut-offs on multiple tram corridors.
Key pain-points for business travellers include the RER B suspension between Gare du Nord and Aéroport CDG 2-TGV after 22:45 each night until Friday, with replacement buses adding up to 45 minutes to airport transfers. On the RER C, evening trains between Juvisy and Paris Austerlitz are cancelled from 23:00, complicating access to the Orlyval interchange. Metro line 14’s full-day closure next Saturday is likely to push extra load onto lines 4 and 1 serving the main department-store district.
![Week-long rail and metro works create heavy disruption for Paris commuters 17-23 November]()
The operators argue that concentrated week-long block-works accelerate commissioning of new signalling ahead of the Olympic timetable. Yet the timing has angered hotel and event organisers who fear missed connections and mounting taxi costs. The regional chamber of commerce is urging companies to switch meetings online or distribute “mobility vouchers” for staff reserving licensed taxis in advance.
For mobility managers the advice is clear: build at least one hour of buffer when scheduling flights out of CDG or Orly this week, and consider routing through Gare de Lyon rather than Austerlitz for provincial rail links. Employers with large commuter populations in the outer suburbs should check whether tele-working exemptions under the new labour-mobility accord of July 2025 can be activated at short notice.
A detailed disruption map and live updates are available on the “Mes Déplacements” app and the RATP X/Twitter feeds; push notifications can be configured by line and time-slot.
