Focus on the extension of line 11

The extension of Line 11 has been inaugurated on June 13, 2024, connecting the Mairie des Lilas station to the new terminus at Rosny - Bois-Perrier. An additional 85,000 passengers are able to use Line 11 daily at the six new stations: Serge Gainsbourg, Romainville Carnot, Montreuil-Hôpital, La Dhuys, Coteaux Beauclair, and Rosny – Bois-Perrier. In practice, this extension allows for a 25-minute journey between Châtelet and Rosny - Bois-Perrier stations.

This project has taken 8 years of construction, resulting in a 6 km extension, the creation of a viaduct, and the construction of new stations in a highly dense urban environment. It represents a significant technical challenge successfully met by the dedicated teams.

The aim of this extension is to enhance the rail service coverage in the eastern part of the Île-de-France region, particularly by boosting access to business areas and facilities such as the André Grégoire Intercommunal Hospital, the Rosny 2 and Domus shopping centers, and the high schools in the Londeau neighborhood. The goal is to fully support the urban development of the Seine-Saint-Denis (93) municipalities served: Les Lilas, Romainville, Noisy-le-Sec, Montreuil, and Rosny-sous-Bois.

The extended Line 11 to Rosny - Bois-Perrier will offer connections to the extended T1 at Val de Fontenay, the RER E, and Line 15 East at Rosny - Bois-Perrier, as well as to the bus lines serving the area.

Discover several videos showcasing some of the new stations of the Line 11 extension:

• Rosny - Bois-Perrier Station: This is the new terminus of Line 11.
• Did you know? An architectural emblem of the Line 11 extension project, the Coteaux Beauclair station features a 600-meter viaduct with a sleek design. This structure, designed by Marc Mimram, reinterprets the architectural codes of the aerial viaducts of Lines 2 and 6 built in the early 1900s for the 21st century.
• La Dhuys and Montreuil-Hôpital Stations
• Romainville Carnot Station

Dans le cadre du prolongement de la ligne 11, la RATP vous propose, à la station La Dhuys, de découvrir une nouvelle œuvre d'art sur votre trajet : #Hydroflux, de Mathieu Merlet Briand.

Avec cette œuvre lenticulaire, inspirée de tableaux impressionnistes, l’artiste révèle la fluidité et le caractère insaisissable de l’eau. L’œuvre monumentale de 15 mètres de long s’anime au gré du déplacement des voyageurs, avec l’apparition et la disparition d’éléments, offrant une expérience visuelle en constante évolution. 

Né en 1990, Mathieu Merlet Briand vit et travaille dans le département de la Seine-Saint-Denis. Il a développé une méthode algorithmique permettant de générer des œuvres lenticulaires à partir de milliers d'images et d'informations en données d'entrée.

Cet artiste a été missionné par la maison de production Quai 36, en charge de la production et de l’installation de l'œuvre monumentale au sein de la station La Dhuys.

The complexity of the Line 11 extension project lies in the simultaneous execution of three major undertakings:

• The actual extension of the line
• The adaptation of existing stations
• The modernization of driving systems and the complete renewal of rolling stock, funded by Île-de-France Mobilités

The new MP14 trains have been gradually replacing the MP59 trains since June 2023. These new trains are much quieter, more energy-efficient, and offer better information, thus enhancing passenger comfort.

Additionally, this extension includes the creation of a maintenance workshop in Rosny-sous-Bois and a new centralized control center for the line in Bagnolet.
