Île-de-France Mobilités and operators RATP/SNCF have warned of extensive maintenance blocks and night closures on multiple Metro and RER lines from 17 to 23 November. Key impacts include full suspension of driver-less Metro Line 14 on Saturday 23 November, nightly shutdowns on RER B between Gare du Nord and Charles-de-Gaulle Airport, and weekday evening cuts on RER A’s western branches.
For corporate travellers flying into CDG, the loss of late-night RER B services means reliance on taxis or ride-shares—adding up to €60 and 40 minutes to airport transfers. Rail commuters between La Défense and suburban tech parks face diversions via Transilien lines, which are themselves operating reduced frequencies after 22:00.

Hotels around major stations are already reporting a spike in same-day bookings as travellers opt to stay overnight rather than risk early-morning delays. Travel managers should alert staff to build in buffer time around meetings and consider approving private-hire receipts where public transport alternatives are unavailable.
The works form part of the accelerated modernisation programme ahead of the Paris 2026 Urban Mobility Plan, and similar week-long blocks are slated monthly through the first quarter of 2026. Companies with frequent Paris travel should review whether flexible-work or video-conference policies can offset the disruption.
