Which Train Goes from CDG Airport to Paris?
The RER B is the direct train from both CDG stations to central Paris — about 34 minutes to Gare du Nord for €14. High-speed TGV trains also run from the CDG 2 TGV station to other French cities and to Disneyland Paris.
Paris Charles de Gaulle Airport has frequent rail connections from its two airport train stations. The RER (Réseau Express Régional) Line B provides direct access to Paris and the suburbs, while TGV high-speed trains connect CDG with other French cities and several international destinations.
The Regional RER B Trains from Paris Roissy Airport
RER B (Blue Line) trains depart from both CDG airport stations. The first train usually leaves at 04:50 and the last at around 23:50. Trains run approximately every 10–20 minutes, with higher frequency during rush hours.
RER B is a convenient and relatively affordable option for reaching central Paris. Travel times depend on your stop:
- Paris (average): ~50 minutes
- Gare du Nord: ~34 minutes
- Châtelet–Les Halles: ~37 minutes
- Saint-Michel Notre-Dame: ~40 minutes
There are also express-style services (often showing Massy–Palaiseau rather than Saint-Rémy-lès-Chevreuse) that skip intermediate stops between the airport and Gare du Nord, making the journey faster.
Keep in mind that the RER network in Paris often operates with different branches. Always check the electronic signs and onboard route displays before boarding. As a general rule, the letter (B) indicates the line and the number indicates the branch (for example, B3 to the airport, while other branches may terminate elsewhere).
Our Tip: Maintenance works are common on the Paris rail network and can cause delays, disruptions, or route changes. Always check the official RATP website for live updates before traveling.
