About Hello Paris

In good hands

Hello Paris is a 50-50 joint venture between two leading public transport operators – Keolis and RATP Dev – set up to operate the CDG Express

This partnership gives Hello Paris a solid foundation in three areas:

• financial capacity, to fund the €260 million investment and manage any challenges that may arise as the service ramps up in its early years;
• operational resilience, drawing on its parent companies’ expertise and resources in areas such as procurement, engineering, safety and lessons learned from past projects;
• organisational know-how, harnessing experience on large-scale projects including passenger services during the Olympic and Paralympic Games in 2024, and the Doha consortium, which has shown how effectively the partners can work together as one team under pressure.

This joint venture was set up in 2018 to meet the project’s challenges and the French State’s expectations, combining both partners’ decades-deep expertise in rail operations, high-density network management, urban integration and service quality – all of which are essential for a rail link embedded in a complex mass transit network

Hello Paris is 100% focused on its aim to provide a reliable, regular, comfortable and convenient rail service that fits seamlessly into every passenger’s journey. To do that, we combine expertise in rail and airport operations, as well as urban mobility, working closely with:

• SNCF Réseau for infrastructure;
• Groupe ADP for the airport hub.

Hello Paris is fully responsible for operating the line and financing the €260 million investment. We work closely with our partners to provide safe and reliable services, maintain the trains, provide clear and timely passenger information, and keep operations running smoothly. Hello Paris obtained its Single Safety Certificate from the European Union Agency for Railways on 17 February 2026, attesting to its compliance with all applicable regulations and its ability to operate trains on the French national rail network.

Hello Paris also decided to open a driving school specifically for the CDG Express. We reviewed close to 10,000 applications to select about 60 drivers and supervisors for training, most of whom had experience in hospitality and airline customer service. 

At Hello Paris, drivers, train managers, supervisors and passenger services staff spend a day a week working alongside colleagues in other roles. The five-month initial training programme makes this versatility possible and is designed to foster a shared culture, enhance operational resilience and nurture a genuine customer-first attitude. One of the CDG Express’s promises is that every member of the team will remain closely and naturally connected to the passenger experience.
