Work on Parisian transport is often synonymous with mystery and uncertainty, especially when it comes to project delivery dates. For example, we could mention the works for the future lines 15, 16, and 17, all extended. However, when it comes to the CDG Express project (CDGX for those in the know), we already have a very specific date. Indeed, from March 28, 2027, the brand-new train service will be operational, fingers crossed for no unpleasant surprises.
A drastic change for everyone
The CDG Express principle is simple. From 5 AM to midnight, shuttles will run every quarter hour, taking all passengers directly from Gare de l'Est to Roissy Airport, in 20 p.Small minutes. 13 trains will take turns throughout the day, offering seating for all passengers, as well as dedicated spaces for luggage storage. All this for the reasonable price of 24€… one way.

So yes, it might seem a bit pricey, but if we had to put a price on happiness, it would probably be this one. Just to remind you, right now, it takes a solid half hour from Gare du Nord, which is 10 minutes longer. And that doesn’t even include the extremely frequent construction work, the stops at stations for regulation, and the traffic interruptions. All this, if you don’t have a Navigo pass, for €13. Especially since for those who already have a metro pass, a 30 to 40% discount is currently being considered.
A project on the right track
If some oppose this project due to its cost, potential noise disturbances (the manager has also funded soundproofing for no less than ...
500 homes) and its lack of stops between Paris and the airport, let's remember that its main purpose will be to relieve the RER B so that it can return to its primary function of daily transport. In any case, the construction is currently on track, and the vast majority of the infrastructure is in place.Si je comprends bien, le CDG Express, c’est pour les touristes, et la ligne 17, c’est pour les Franciliens ? 😂 pic.twitter.com/HDJ3VUcXvN

Among the upcoming steps, there’s the connection of the signaling and the electrification of the overhead line during the Pentecost weekend, which will involve no less than 300 people. After that, different train sets will be put in place for testing sessions. The full line of the CDGX will be in operation starting June 2026, leading up to a definitive opening in spring 2027!
