Summer modernisation works continue to affect France’s transport network. In Toulouse, Tisséo reshaped several bus services in the Fenouillet suburb, while SNCF night-train services between Paris and Toulouse suffered severe delays in mid-July due to a fallen tree. In the Tours region, extensive road works divert north-south traffic on the peripheral ring and affect the A10. 

In August 2026, the Paris and Île-de-France region face extensive disruptions. Scheduled works include nightly closures of the Périphérique ring road tunnels—such as Maillot, Brancion, and Exelmans—between 21:30 and 06:00. RATP and SNCF service alterations affect multiple lines: Metro Line 8 is not stopping at République, Line 13 is interrupted between Saint-Denis-Université and La Fourche, and RER A is missing Nation. RER B, C, and D also face various nighttime suspensions or section closures, including RER B between Denfert-Rochereau and Mitry-Claye and RER C between Dourdan la Forêt and Brétigny.

Commuters have reported overcrowding on replacement buses and congestion on Metro Line 4. In Brittany, the SNCF network has been strained by heat and equipment failures, including incidents where TGVs were halted at Montauban-de-Bretagne and Saint-Brieuc, and 600 passengers were stranded at Lamballe. 

Additionally, security-related station closures may occur between 17 and 23 August due to police prefecture requests for major events. Ongoing maintenance continues to impact Metro Line 12 with nighttime interruptions on Wednesdays and Sundays, and RER A between Vincennes and Noisy-le-Grand – Mont d'Est.
