Find out about the major projects for the modernisation of the Paris metro including extensions and new lines.

Modernisation and extension of Line 4

Line 4 will be extended to the south, from Mairie de Montrouge to Bagneux (92).

Along with the extension, Line 4 is going to be fully automated, on the model of Line 1.

Modernisation of Line 6

Since autumn 2018, Line 6 has embarked on an ambitious modernisation programme with the preparation and reinforcement of the tracks and the adaptation of infrastructure to prepare for the introduction of new trains on the line. A new central command and supervision system will be put in place when these trains enter service to improve timekeeping on the line.


Modernisation and extension of Line 11

The extension of Line 11 to Rosny-Bois-Perrier (93) will serve the towns of Lilas, Romainville, Noisy-le-Sec, Montreuil and Rosny-Bois-Perrier.

Along with the extension, Line 11 is being modernised with existing stations updated in preparation for the scheduled replacement of the trains.

Extension of line 12

The extension of Line 12 will link with Mairie d’Aubervilliers (93).

Northern and southern extensions of Line 14

The extension of Line 14 to the north will link to Mairie de Saint-Ouen (93) with the creation of four stations: Pont Cardinet, Porte de Clichy, Clichy Saint-Ouen and Mairie de Saint-Ouen.

At the same time as the extension, the Line 14 stations are being modernised to adapt to welcome new passengers in the best conditions.

The extension of Line 14 to the south will reach Orly Airport (91, 94) and serve ten towns between Paris, Val-de-Marne and Essonne.

And to go further: Grand Paris Express Lines 15, 16, 17 and 18

Grand Paris Express (GPE) is a public transport project consisting of the extension of Line 14 (see above) and the construction of four automatic metro lines around Paris: Lines 15, 16, 17 and 18.

The metro network will almost double in size. In fact, more than 200 kilometres of new lines and 68 metro stations will enter service. All of these new lines should welcome more than one million passengers, attracted by greatly reduced transport times and the best possible quality of service. The passenger flow on the “original” network will be better spread.
