Roissy–Picardie rail link

Grand ProjetIn progress

Published on Updated on

The Roissy–Picardie rail link will improve daily travel to the Roissy employment hub from Picardy and north-eastern Val-d’Oise, while also strengthening connections between the southern Hauts-de-France region and both the TGV network and the Île-de-France area. Led by SNCF Réseau, the project involves building a new 6.5-km rail section allowing trains to travel at speeds of up to 160 km/h, along with upgrades to the existing network and station improvements at Survilliers-Fosses, Aéroport Charles de Gaulle 2 TGV, and Amiens. Work began in 2024 and will continue over the coming years.

Objectifs du projet

Alongside the introduction of new rail services (both high-speed and regional trains), the Roissy–Picardie rail link aims to address national, interregional and local travel needs by:

  • Improving daily travel to the Roissy economic and employment hub from Picardy and north-eastern Val-d’Oise;
  • Supporting urban and regional development in the areas served;
  • Facilitating high-speed rail access for residents of Picardy and the Hauts-de-France region;
  • Enhancing rail-to-air connections at Aéroport Charles de Gaulle 2 TGV station;
  • Providing a new route into Île-de-France for people living in Hauts-de-France, helping relieve pressure on services to Paris Gare du Nord.

The project is part of a wider commitment to sustainable mobility by encouraging modal shift from road to rail.

Funding

The Roissy–Picardy rail link is jointly funded by the European Commission, the French State, the Hauts-de-France Region and eleven local authorities in the Hauts-de-France area. The project is being delivered by SNCF Réseau and SNCF Gares & Connexions, each within their area of expertise.

Aménagements

The Roissy–Picardie rail link includes the following infrastructure developments:

Construction of a new 6.5-km section connecting the Interconnection high-speed line with the conventional Paris–Creil line:

  • This section will be electrified and allow trains to run at speeds of up to 160 km/h. 
  • The southern portion will be raised on an embankment and include four railway bridges over the LGV Nord, the RD9, the A1 motorway and a wildlife crossing in the Argenteuil woods.
  • The northern portion will be in a cutting, featuring three road bridges: one for a farm track north of Villeron, another for the RD317 and a third for Chemin des Peupliers in Marly-la-Ville.
  • A retaining wall will be built where the new line connects to the existing Paris–Creil line.

Upgrades at Survilliers–Fosses station:

  • Construction of two platforms and a town-to-town footbridge spanning the entire set of tracks
  • Installation of façade-mounted noise barriers for around thirty homes near the station

Upgrades at Aéroport Charles de Gaulle 2 TGV station:

  • Construction of a new platform
  • Development of access routes to the new platform

Upgrades along the Paris–Creil line:

  • Modernisation of signalling
  • Reinforcement of the electrical supply at the Gonesse substation
  • Electrification of tracks within the Amiens station area

Upgrades along the high-speed lines:

  • Renewal of five signalling systems
  • Adjustments to the signal boxes and traffic management systems in Lille

Construction of a wildlife overpass in the Chantilly Forest (Orry-la-Ville)

 

 

In a second phase of the project, subject to future changes in traffic levels or service patterns, the following additional works may be carried out:

Extension of the new tracks between the Marly-la-Ville junction and Survilliers–Fosses station. This would increase the number of main tracks from four to six in this section (including two local tracks used by RER D), requiring the existing rail corridor to be widened on the eastern side.

Construction of a fourth track and a new platform at Chantilly–Gouvieux station (on the Gouvieux side).

Integration measures

Addressing environmental considerations

Environmental issues were central to the planning of this project, which was developed through extensive consultation with all stakeholders. This approach led to the selection of the least impactful route, as presented in the public inquiry ahead of the declaration of public utility in 2021. The project’s environmental scope includes physical, natural and human environments, as well as landscape and heritage concerns.

From the outset, SNCF Réseau has implemented the “Avoid, Reduce, Compensate” (ARC) approach, applying it throughout the design process in accordance with regulatory requirements and SNCF Réseau’s commitments.

Avoidance and reduction measures 

Key avoidance and reduction measures include:

  • The chosen route steers clear of both existing and planned residential areas in Vémars and Villeron, keeping the nearest homes at least 600 metres away.
  • Impacts on current and future business zones have been kept to a minimum.
  • Agricultural activity has been factored into the design, from route selection to the development of mitigation and compensation measures. The proposed agricultural compensation plan was approved by the Val d’Oise CDPENAF on 17 November 2023. 
  • Agricultural access routes will be restored, and the intercepted irrigation network near the LGV Nord will be maintained.
  • Tree clearing in the Argenteuil woodlands will be limited by using a section of the existing clearing beneath the high-voltage power line.
  • Natural environment concerns have been carefully considered, with ecological corridors preserved: a large-wildlife crossing is planned through the Argenteuil woods in Villeron, wildlife-friendly crossing structures will be constructed, and tailored measures for smaller species will be implemented.
  • Planned features such as specialised construction techniques, longitudinal drainage and retention basins are designed to protect both groundwater and surface water from any adverse impact.

Public infrastructure and heritage assets have been avoided and protected wherever possible.

Proposed service offering

Service model

The agreements signed in 2017 between the French State, the Hauts-de-France Region, 11 local authorities in the Oise and Somme departments, and SNCF provide for a dual service model combining high-speed trains and regional trains. These services will be added to the existing traffic on the Paris Gare du Nord–Creil–Amiens line and will include:

  • A combined high-speed and regional train service to Amiens: 2 return high-speed services + 3 return regional services, connecting with TGV services at Aéroport Charles de Gaulle 2 TGV station.
  • A regional train service operated by the Hauts-de-France Region to Creil and Compiègne, with a broad operating window throughout the day and enhanced peak-time services (trains every 30 minutes during peak hours on the Creil–Roissy line, and hourly on the Compiègne–Roissy line).

Journey times

Short-distance travel times
Long-distance travel times

Fares

Fares for passengers will be determined in due course by the competent organising authorities for regional traffic (Hauts-de-France Region and Île-de-France Mobilités), as well as by the train operators providing high-speed services.

Passenger numbers

Once in service, the line is expected to carry 4 million passengers per year (around 15,000 journeys per day), with nearly three-quarters of journeys related to daily commuting.

Actualités du chantier

Le chantier a débuté en 2024 et se poursuivra durant les prochaines années.

SNCF Réseau réalise la liaison ferroviaire Roissy-Picardie en coordonnant les interventions des entreprises et en restant à l'écoute des élus et des habitants des communes où se déroulent les travaux tout au long de la phase chantier.

La préservation du cadre de vie des riverains est la priorité. L’organisation du chantier s’effectue en réduisant au mieux les implications sur la vie quotidienne. La prise en compte des enjeux environnementaux est aussi un élément essentiel du projet, y compris dans sa phase chantier.

  • Mars 2025 : SNCF Réseau protègera 12 hectares d'espace naturel à Survilliers pour les 50 ans à venir 

Dans le cadre de la démarche « éviter, réduire, compenser » mise en œuvre sur le projet, SNCF Réseau a récemment signé une convention de partenariat avec la commune de Survilliers. Cet accord acte la mise à disposition de près de 12 hectares de propriété communale au profit de SNCF Réseau, en compensation des impacts du projet Roissy-Picardie sur les espèces protégées et les zones humides. La parcelle, qui fut anciennement une carrière, a été fortement dégradée par des occupations illicites par le passé. Un programme d’actions sera déployé pendant 50 ans pour renaturer le site, restaurer la mare et améliorer la biodiversité, tout en permettant un accès raisonné du public.

  • Mars 2025 : des travaux inhabituels au milieu de l'autoroute

Le tracé de la liaison ferroviaire Roissy-Picardie rencontre l’autoroute A1 au niveau de la commune de Vémars. Son franchissement nécessite la réalisation d’un ouvrage d’art qui permettra à la future voie ferrée de surplomber l’autoroute.

La construction de cet ouvrage massif, d'une longueur de plus de 60 mètres répartie en 3 travées, s'échelonne sur 13 mois environ. Actuellement, les piles et culées qui supporteront le tablier sont érigées de part et d'autre de l'autoroute, mais aussi au milieu du terre-plein central ! Ces travaux peuvent susciter la curiosité des usagers. Mais prudence, cette étape de réalisation impose une réduction temporaire des voies de circulation.

Pour vous permettre d’observer ces travaux dans des conditions plus sécurisées, voici une photographie du chantier... vu du ciel!
