Paris CDG Express train is set to change how passengers move between Charles de Gaulle Airport and central Paris, with a confirmed opening date of 28 March 2027. The service introduces a direct rail link that removes many of the delays and uncertainty tied to current airport routes.
The CDG Express will run between Paris Charles de Gaulle Airport and Gare de l’Est, located in the 10th arrondissement. The journey will take around 20 minutes, offering a fixed and predictable alternative to existing transport options. Trains are scheduled every 15 minutes, operating daily from 5am to midnight.
The idea behind the CDG Express is simple: reduce airport travel time and remove commuter congestion from the journey. Today, most passengers use the RER B line, which takes roughly 34 minutes to reach central Paris and is often affected by stops and delays.
The new service cuts that travel time almost in half. More importantly, it removes the variability that comes with a shared commuter rail line. For travelers arriving in Paris, that consistency matters as much as speed.
The final ticket price has not yet been announced. However, several fare rules are already confirmed.
Children under 16 traveling with family will be able to ride for free. Residents of the Île-de-France region using a Navigo pass will receive a discount estimated between 30 and 40 percent.
For context, the current rail fare from central Paris to Charles de Gaulle Airport is €11.80 for a single trip.
The CDG Express is not being introduced in isolation. It is part of a wider set of transport improvements across northern Paris.
One key project is a pedestrian tunnel linking Gare du Nord and Gare de l’Est. Although the two stations are only about 500 meters apart, they handle close to 800,000 passengers every day. The tunnel is designed to reduce walking congestion and simplify transfers between major rail lines.
Completion of the tunnel is planned for spring 2027, aligning closely with the launch of the CDG Express.
Paris is also developing Metro Line 17, which will connect Saint-Denis to Mesnil-Amelot through Charles de Gaulle Airport.
The project will open in phases. The first section between Saint-Denis and the airport is expected by mid-2027. The extension toward Parc des Expositions will follow in 2028. Full completion is planned for 2030.
Once operational, Metro Line 17 will add another transport option for airport access, supporting both local commuters and long-distance travelers.
The introduction of the CDG Express signals a shift in how Paris handles airport connectivity. Instead of relying on a shared commuter rail system, the city is creating a dedicated airport line designed for speed and reliability.
For travelers, the impact is practical. Arrival times become easier to predict. Transfers to central Paris are simplified. Pressure on existing rail lines is also expected to ease once the service begins.
