We thought the saga had wrapped up with the extensions to Saint-Denis Pleyel and the Orly Airport. Yet in 2026, construction signs stubbornly linger on the line 14 of the Paris metro. If the extension is indeed underway, the modernization is a ongoing story that never truly ends.
These new interruptions, typically in the evenings or on select weekends, are meant to complete the rollout of the new autonomous driving system and to lay the groundwork for interconnections with the upcoming lines 15, 16 and 17 of the Grand Paris Express.
According to RATP, these new features are designed to help optimise how incidents are resolved and how the line's regulation systems operate, notably including backward movement, energy-use optimization, and the management of platform screen doors. Regarding backward movement, it would allow, in the event of a sudden service disruption, a train to be brought to a platform at the nearest station—even if that platform lies behind the affected train—to avoid getting stranded in a tunnel.
Shut this spring in the evenings on Thursday, March 26 or during the day until 2 p.m. on Sunday, April 5, Line 14 continues to urge riders to check ahead regularly to avoid getting stuck when trying to get home late, or when traveling on weekends. If these closures remain occasional, the promise of a line that is “finally trouble-free” after years of headaches has not yet been fully delivered to commuters.
Moreover, the work also includes finalising certain finishes in the new stations and adapting the platforms to accommodate the massive flow of travelers, with around a million passengers per day expected with the Grand Paris Express on Line 14.
