The CDG Express, the train that was meant to streamline journeys between Paris and its main airport, has still not welcomed a single traveler, even though construction began several years ago. A flagship promise associated with the Paris 2024 Olympic Games, this direct rail link was to symbolize the modernization of the Île-de-France network in the face of the world. Yet, between the landscapes that hosted the Olympic events and today, the line remains painfully quiet; no train has yet left its terminus. A costly symbol, financed with billions, that raises questions about both the management of large public projects and the reliability of our infrastructures.
- The CDG Express budget has risen from 2.1 to 2.6 billion euros, financed without direct public subsidies but through a state loan and the shareholders’ funds.
- The completion, initially planned for the 2024 Olympic Games, is now set for March 28, 2027, largely due to legal challenges that delayed the project.
- The Hello Paris operator, contracted for fifteen years, aims for more than 9 million passengers a year at about 25 euros per trip to make the line financially viable.

A 2.1‑billion‑euro project idling since the Olympic Games
The calculation is simple to make, but painful to state: more than two billion euros have already been poured into this project, with not a single passenger able to board. The CDG Express was supposed to embody the rail showcase of the Paris 2024 Olympic Games, linking the capital to Charles de Gaulle Airport in record time. A piece of infrastructure designed to dazzle visitors from around the world and ease movements during the global event. Except that the Games are now a memory, the sports facilities have long found their audience, and this line, for its part, remains at the platform.
This situation illustrates a striking paradox: while France managed to deliver spectacular projects on time for the Games, this direct rail link project has become bogged down in delays that far exceed initial forecasts. A paradox for an infrastructure intended to carry the image of a country capable of keeping its commitments on the international stage.
How a presidential promise turned into a financial sinkhole
Originally, the CDG Express was to be operational by 2023, then the date was pushed back to 2024 to coincide with the Olympic Games. Seven years of work later, the bill exploded: the initial budget of 2.1 billion euros was revised upward to reach 2.6 billion euros, financed by the State, the ADP group, SNCF Réseau, and the Caisse des dépôts, without direct recourse to public subsidies but via a state loan and the shareholders’ own funds.
The accumulated delay did not come without further budgetary consequences. The State had to grant an additional 30.21 million euros to compensate for the operator’s lost revenue and the inflation experienced during these years of waiting. Added to this is the contract awarded to the Hello Paris consortium, in charge of operating the line for the next fifteen years, for 200 million euros per year. A colossal financial commitment, which assumes heavy ridership to hope for profitability someday.
2027: the new date that convinces no one anymore
After several successive announcements and as many disappointments, an official date was finally set: Sunday, March 28, 2027. Almost three years after the promise originally tied to the Olympic Games. The delay is largely explained by a series of lawsuits filed by opponents of the project, significantly delaying the progress of the works. It took until April 2022 for the Paris Administrative Court of Appeal to definitively validate the environmental permit for the line, finally paving the way for its realization.
But after so many postponements, it is difficult for Île-de-France travelers as well as railway sector observers to fully believe in this deadline. Fatigue has set in, and every new announcement is now met with cautious skepticism. That said, the promised technical features remain appealing on paper: a 32‑kilometer direct link from Gare de l’Est to Terminal 2 of the airport, completed in just 20 minutes, with a train every 15 minutes, seven days a week, from 5 a.m. to midnight.
Between cascading delays and cost overruns, what the CDG Express fiasco really reveals
Beyond the numbers and dates, this file reveals above all the structural fragilities that can stall a major French infrastructure project. Repeated legal challenges, a health crisis that disrupted construction sites, political arbitrations favoring other daily priorities: all these factors piled up to transform an Olympic promise into a genuine administrative and financial saga.
The stakes go far beyond the comfort of international travelers. The primary objective of this line remains to relieve congestion on the RER B, whose ridership continues to grow relentlessly, much to the frustration of daily commuters crammed into overcrowded carriages. For the economic equation to finally add up, Hello Paris is targeting an ambitious goal: more than 9 million passengers a year, at a fare around 25 euros per trip, not included in the Navigo pass. A bet far from guaranteed, given how public confidence has been severely tested by these years of hesitation.
Ultimately, this long-awaited link vividly illustrates France’s difficulties in delivering major projects on the promised timelines, despite substantial financial resources. It remains to be seen whether, once the first trains finally roll out in spring 2027, the CDG Express will be able to convince enough travelers to justify this extraordinary investment. A question that, for now, remains suspended, like the rails of an unfulfilled promise.
