Today, 6 May 2024, the RER commuter rail network in the so-called Île-de-France area in and around the French capital Paris was extended by eight kilometres of line and three new stations: Line E was extended largely underground to Nanterre-la-Folie. It offers connections to various other lines: In Porte Maillot to the M1 metro, RER line A and the T3b tram, in La Défense to the M1 metro and in future to the M15, the RER line A, the T2 tram and the regional lines L and U. At the current Nanterre-la-Folie terminus, it will be possible to change to the new suburban metro lines M15, M16 and M17, which are currently under construction. By 2026, the line is to be extended beyond Nanterre-la-Folie on the existing Transilien-Regional J to Mantes-la-Jolie, a distance of 55 kilometres from the central Haussmann Saint-Lazare junction to Mantes-la-Jolie.

The journey from Haussmann Saint-Lazare station to Nanterre-La Folie takes 12 minutes.

The first of the new generation of seven-car RER double-decker trains with fully barrier-free access, supplied by Alstom and designated RER NG, are now operating here. A total of 155 of these trains will run on lines D (125 units) and E (130 units) in future.

For the time being, there will only be a 15-minute interval between Magenta and Nanterre La Folie from 10.00 a.m. to 4.00 p.m. on the new route of line E; however, this is to be significantly extended in the course of the year. For journeys on the eastern sections of line E in the direction of Tournan or Chelles Gournay, you currently have to change at the same platform in Haussmann Saint-Lazare. But this is also set to change in the future.
