The future RER E Nanterre La Folie station

The third new station in the Eole project (extension of the RER E to the west) will be located on the Groues railway line.

This intermodal station at the heart of the renovated Les Groues district will contribute to its dynamism and the development of intermodality and soft modes (bicycles, pedestrians, etc.). It will help to reduce the saturation of the RER A and will also be a possible alternative in the event of an incident, with a 5-minute walk between the two RERs.

Passenger flow will be smoother, simpler and linked to public spaces, thanks in particular to an imposing main entrance 8 metres high and 12 metres wide. It will be 100% accessible and will accommodate more than 10,000 passengers per day, with 22 trains at peak times, 16 trains from the East and 6 from the West when it is fully operational.

The project to extend the RER E to the west requires the construction of sidings and service buildings. The site known as the "railway island" to the north of the Eole station (consisting of former warehouses and workshops) will be developed for the installation of sidings and a service building.
