RER E service to La Défense and Nanterre from May 6, 2024!

Paris La Défense

The big day has arrived! From May 6, 2024, the first passengers will be able to take the new RER E line to central Paris from Paris La Défense. It's also an opportunity to discover the two new stations, La Défense Grande Arche and Nanterre-La-Folie, and the facilities surrounding them.

After several years of construction work, the first passengers will be able to take the RER E from Nanterre or La Défense on Monday, May 6, 2024! A long-awaited opening, just a few weeks before the start of the Paris 2024 Olympic and Paralympic Games.

To access this new section from Paris, you'll need to take the RER at Magenta - Gare du Nord, or Haussmann - Gare Saint-Lazare. Lines connecting with the RER E are : RER A, B, C, D, trains on lines J, L, H, K, P, U, ter and TGV, metro lines 1, 2, 3, 4, 5, 7, 9, 12, 13, 14 and T1, T2, T3b, T4.

A gradual opening

From Monday morning until the Olympic Games, RER E will run between 10 a.m. and 4 p.m. with a train every fifteen minutes, and at weekends from 10 a.m. to 8 p.m. with the same frequency. During the period of the Olympic and Paralympic Games, the transport offer will be supplemented during peak hours, in the morning and evening, between Porte Maillot and Nanterre. By the end of 2024, the 34 RER NG trains will have been delivered, increasing frequency with a train every 4 minutes in rush hour, and every 6 minutes in off-peak hours. In 2026, the line will be further extended to the west, as far as Mantes-La-Jolie.

Shorter journey times

  • Nanterre - Porte Maillot in 6 minutes, compared with 12 minutes today;
  • Nanterre - Magenta in 12 min, compared with 25 minutes today;
  • Nanterre - Mantes-la-Jolie in 37 minutes, compared with 57 minutes today.

How do I get to the stations?

To reach the platforms of La Défense Grande Arche station from the slab, three new direct accesses to the platforms have been created to complement those at CNIT, and connections with existing transport lines:

  • Place Carpeaux access, for easy access to the Faubourg de l'Arche district;
  • Parvis de La Défense access, in front of the CNIT, for direct access to the office towers and shopping centers;
  • Gambetta-Coupole access, on avenue Albert Gleizes.

Nanterre-La-Folie station is located on rue de la Garenne, in the center of the Groues district. An imposing 8-metre-high, 12-metre-wide entrance has been created to access the station, complemented by two bridges that facilitate crossing of the tracks and access to the future district.

Two new stations for two major challenges

Three new stations have been built to extend the RER E to the west: Neuilly Porte Maillot - Palais des Congrès, La Défense Grande Arche and Nanterre-La-Folie. Two of these stations are located in the Paris La Défense area, and have been built using the most advanced technology.

La Défense Grande Arche station

  • La Défense Grande Arche station

For the La Défense station, known as the "cathedral station", the challenge was to build an 18,000 m2 underground station 32 meters below the CNIT, which remained open throughout the construction work. Teams performed a feat of technological and human ingenuity to "re-underpin" the foundations of the existing buildings. Thanks to its numerous elevators and escalators, the station will be able to accommodate over 70,000 passengers a day.

Nanterre-La-Folie station

  • Nanterre-La-Folie station

The Nanterre-La-Folie station is much more than just a station. It represents a genuine service for the future Nanterre district of Les Groues, which is being developed by the public corporation Paris La Défense. Its imposing entrance will contribute to the district's dynamism and open it up.

Les Groues is destined to become a mixed-use district, combining housing, offices, businesses, shops, green spaces and private and public facilities. The arrival of the RER will also make it an attractive, accessible and pleasant district, connected to the business district.

The 12,000 m² train station will be able to accommodate almost 15,000 passengers per day, and will increase in size in the future with the arrival of line 15 west.
