Another challenging morning for transit users in Île-de-France on Thursday, February 26, 2023. After a Wednesday already marked by significant disruptions on Lines B, D, and E, the issues have worsened this morning, with signal failures shutting down parts of the network since the early hours.
On the RER B, the incident originates at the Gare du Nord, where a "low zone" confuses the signals by falsely indicating the presence of a train on the track. For safety reasons, trains must operate under sight conditions, leading to slowdowns and service cancellations across the entire line. Southbound trains are the first to be affected, but the effects are felt in both directions, especially between Gare du Nord and Châtelet - Les Halles. Delays, service adjustments, and cancellations are still expected at this time of day.
The RER D line is not spared. Service is disrupted between Stade de France and Villeneuve-Saint-Georges in both directions due to a fresh signal system failure at Châtelet-Les-Halles. Commuters should anticipate delays of up to 10 minutes, along with changes to the usual train schedule and occasional cancellations.
Earlier this morning, train traffic was completely halted on the RER D line between Juvisy and Corbeil-Essonnes, via Ris-Orangis, between 5:30 and 7 a.m. By 7:45 a.m., the situation was still tense between Juvisy and Malesherbes, this time due to a signal failure in the Évry-Val-de-Seine area in Essonne.
To better tailor your journey, it's recommended to regularly check official channels. The RATP and Île-de-France Mobilités provide real-time updates on their websites and apps. The RATP's X (formerly Twitter) account also offers quick updates during such incidents. Navigation apps like Citymapper or Google Maps can also suggest alternative routes, factoring in ongoing disruptions.
While normal service is being restored, commuters on the RER B and RER D lines are advised to expect longer delays and to check train availability before heading out.
