Transport disruptions in Paris and Île-de-France: this week's schedule, December 15–21, 2025

Public transportation in Paris and the Île-de-France region is entering its final week before the Christmas holidays, with some disruptions scheduled from December 15 to 21, 2025. If you're planning to visit the Christmas markets or do some last-minute shopping, expect some interruptions on the metro, RER, Transilien trains, and trams, mainly in the evenings. The RATP and the SNCF are continuing their maintenance work ahead of the holiday break. Let’s take a look at all the scheduled service disruptions this week.

Which metro and tram lines are affected from December 15 to 21?

On the Paris metro side, disruptions remain minimal:

• Line 1: Until January 4th, access to Tuileries station will be closed every weekend from 4:00 PM to 11:45 PM due to high visitor numbers at the Christmas market. If you're heading to the Tuileries this weekend, it's better to get off at Concorde or Palais-Royal stations.

On the tramway network, the situation remains complicated across several lines:

• T1: Passenger traffic is currently suspended between Asnières-Quatre Routes and Gare de Saint-Denis, with disruptions on the rest of the line, following vandalism by a third party at L'Île-Saint-Denis. During the night of Thursday, May 15 to Friday, May 16, 2025, a boat collided with the bridge connecting Saint-Denis to Île-Saint-Denis. A replacement bus service is in operation. Full resumption of service is not expected until summer 2026.
