About Hello Paris

Hello Paris, your train manager

Hello Paris is a rail company set up to operate the CDG Express. It was formed through the merger of two leading public transport operators: Keolis and RATP Dev, on an equal footing.

This backing provides a guarantee of financial stability:

• financial, to fund the €260 million investment and absorb the uncertainties of ramp-up during the first years of operation;
• operationally, through access to the parent companies’ expertise and resources (procurement, engineering, safety expertise, lessons learnt);
• organisational, through lessons learnt from large-scale projects such as hospitality services during the Olympic Games or the consortium deployed in Doha, which demonstrated the duo’s ability to combine their cultures under operational pressure.

This consortium was formed in 2018 to address the project’s challenges and meet the government’s expectations. It brings together the proven expertise of both operators: rail operations, managing dense networks, urban integration and service quality. An essential combination for a rail link that is also integrated into a complex mass transit system.

Hello Paris embodies a high standard of rail service: reliability, punctuality, comfort and seamless integration into passengers’ journeys. It coordinates expertise in rail, airports and urban mobility, working closely with:

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

Hello Paris bears full responsibility for the operation of the service as well as thefinancing of the investments required for the service (€260 million). It ensures the safety of operations, the reliability of the service, the maintenance of trains, the quality of passenger information and the continuity of operations, in close collaboration with its partners. On 17 February 2026, the company obtained its Single Safety Certificate (SSC) issued by the European Railway Agency, certifying its regulatory compliance and its ability to operate trains on the national rail network.

Hello Paris has decided to set up a driving school specifically for the CDG Express. 10,000 applications were reviewed to select around 60 trainee drivers and supervisors, the majority of whom came from the hospitality and aviation sectors.

At Hello Paris, drivers, train managers, supervisors and reception staff spend one day a week working in a colleague’s role. This versatility is made possible by an initial five-month training programme, designed to forge a shared culture, build operational resilience and develop a genuine customer focus. One of the CDG Express’s promises is that every member of the team remains, naturally and sustainably, at the heart of the passenger experience.
