Châtelet–Les Halles RER hub

As part of the urban redevelopment of the Les Halles area being undertaken by Paris City Council, the Châtelet–Les Halles RER hub is undergoing major refurbishment to allow it to serve customers better.

Initiated by Paris City Council, the Les Halles redevelopment project provides for the improvement of the Châtelet–Les Halles RER hub, which lies at the heart of the Ile-de-France public transport system, being used by more than 750,000 passengers each day.

Châtelet–Les Halles has more passengers and trains than any other underground station in the world. After 30 years of operation, major improvements to this heavily frequented station had become indispensible. An initiative conceived in partnership with the Ile-de-France Region, Paris City Council, STIF and Espace Expansion, the renovation of the site has several aims:

  • To help “open up” the station by improving accessibility: not only by making it easier to find in the city, but by facilitating access for people with reduced mobility;
  • To improve quality of service and passenger comfort (walkways, spaces, etc.) ;
  • To improve the fire safety system and evacuation conditions.

As a key player in the day-to-day operation of the station, RATP was appointed project owner. The technical complexity inherent in such a project is further increased by the fact that the station will remain open and accessible to transport users throughout the execution of the works.

Key facets of the project

The project aims to construct a new identity for the station, making it more welcoming and easier to navigate. To this end, RATP's actions include:

Halles 2

  • The creation of a major new entrance in Place Marguerite de Navarre. This is a key aspect of the project, which will not only provide quick, direct access to the metro and RER, but also create an above-ground structure dedicated to the station.
  • The extension of the Berger and Rambuteau entrances from level -3 to level -4. The installation of new escalators between these two levels will make it easier to get to the passenger hall from the shopping centre.
  • The renovation, restructuring and expansion of the RER passenger hall.

Following a call for tenders, RATP selected architects Patrick Berger and Jacques Anziutti to redesign the station and its entrances.
