M12 extension to Mairie d’Aubervilliers
As part of the 2007-2013 State-Region project agreement, phase 2 of the M12 extension to the centre of Aubervilliers includes the construction of two new stations – Aimé Césaire and Mairie d’Aubervilliers – by year-end 2019.

Using the tunnel constructed during phase 1 of the M12 extension project, two new stations will be created, bringing the centre of Aubervilliers to within 6 minutes of Paris-Porte de la Chapelle. Phase 2 of the extension also covers the construction of two technical structures (ventilation and emergency access), and the adaptation of an additional access point at Porte de la Chapelle, to improve accessibility for persons with reduced mobility. The M12 extension will also connect with the Front Populaire station, once the T8 extension towards Paris is completed.

  • Trains will run every 2 minutes during peak hours
  • Travel time between Aubervilliers and Paris-Saint- Lazare: 20 minutes

02. Service quality

  • Modern, innovative stations: the two new stations will incorporate modern architecture and amenities, blending glass, metal, and concrete. Passenger spaces will be designed to guarantee smooth traffic flows and optimal safety conditions.
  • A low energy consumption, geothermal heat exchange system will be integrated in the foundations to meet the energy needs of the Mairie d’Aubervilliers station.

In this booming sector northeast of Paris, the M12 extension will meet its goal of bringing the centre of Aubervilliers to within 6 minutes of Paris.
