Location

From 2030, Nanterre La Folie will also be a station on Line 15 of the Grand Paris Express extension of the Paris Métro. The station is being constructed on an adjacent plot and will be connected to the RER station by an underground corridor.^[3]

An extension of Line 18 from Versailles Chantiers to terminate at Nanterre La Folie has been proposed for construction after 2030,^[4] and a possible extension of Line 17 from Saint-Denis–Pleyel appeared on early plans of the Grand Paris Express project. A proposed future Line 19 would also terminate at Nanterre–La Folie and connect it to Charles de Gaulle airport via Argenteuil and Garges-lès-Gonesse.^[5]
