Extension of line 11 of the Paris Metro, first phase completed

ETF, in partnership with TSO (agent), is responsible for constructing the eastern extension of line 11 for its client, RATP. With a 6.5 km long track platform and the creation of six new stations, this extension completes the network in this part of Seine-Saint-Denis (93), offering connections to several key lines in the network: RER E, the future line 15 (Grand Paris) and four bus lines.

Begun nearly two years ago, the first phase of work was completed in April 2021 with the construction of the Rosny loop railway system (future terminus) and the train maintenance workshop (AMT). This more modern workshop will replace the existing one. It is designed to accommodate all routine maintenance activities, cleaning and most of the storage.

In total, the consortium’s operational teams have already built more than 4,400 linear metres of track: elevated tracks on stilts, embedded tracks and ballasted tracks. They have also installed 12 sets of points, 8 in the maintenance workshop and 4 in tunnels.

The consortium is now beginning preparations for the second phase of the project, which will start in July 2021. The teams will begin building the rail system from the Rosny-Bois-Perrier terminus, passing through the viaduct of the future Coteaux Beauclair station, then travelling up the tunnel to connect the existing track to the Mairie des Lilas station.
