The 32-km fast «CDG Express» line will connect Charles de Gaulle Airport to Paris Gare de l’Est train station in 20 minutes. With a service of one train in each direction every 15 minutes from 5 AM to midnight, this connection is key to relieve traffic to and from Paris.

For this important project of Greater Paris, SNCF RESEAU awarded CERTIFER as Notified Body, Designated Body and Assessment Body. Thus, CERTIFER will carry out the assessment of Infrastructure, Energy, Control-Command and Signalling subsystems.

The CDG Express’ commissioning is scheduled for 2023 and would allow the absorption of the expected air traffic growth (≈80 million passengers by 2025 vs. 65 million in 2015).
