Gare Nanterre-La-Folie ligne 15 Ouest

The transport offer in the Groues district, served by the RER E in 2024, will be completed by the metro line 15 by 2030. This new line, equipped with automatic trains, will link Nanterre-La-Folie station to Fort d'Issy-Vanves-Clamart in 15 minutes, compared with 45 minutes today.

The aim of Line 15 West is to strengthen the development of the economic hub of western Paris, particularly La Défense, Europe's leading business district, by linking it to other strategic points in Greater Paris, such as Paris-Charles de Gaulle and Le Bourget airports.

More than 800,000 inhabitants will thus benefit from new travel possibilities, completed by connections with the other lines of the Grand Paris Express and the Transilien, RER, metro and tramway lines. By 2030, together with lines 15 South and 15 East, it will form a major 75-kilometre ring road around the capital. The waiting time between two trains varies according to the time of day and the week, with a train every 2 to 3 minutes on average.

Benefits for passengers

• By 2030, line 15 West will offer optimised connections with the Transilien L and U lines, metro 1, RER A and E lines, tramways and surrounding bus lines.
• La Défense will be 13 minutes from Saint-Denis Pleyel (compared with 26 minutes today)!
