CDG Express is a railway line currently under construction. It will connectGare de l'Est inParis andCharles de Gaulle Airport, aiming to alleviate congestion on the existingRER B line. Originally planned for 2006, the opening was pushed back several times, most recently to 28 March 2027.[1] Upon completion, passengers can expect to travel between the airport and Gare de l'Est in just 20 minutes, covering a distance of 32 kilometres (20 mi).
Charles de Gaulle Airport is one of few major international airports without anexpress link to the city centre. The airport is served byRER B, however this line is also heavily used by commuters. 30% of passengers travelling to the airport use RER B.[2]
The airport is also served byhigh-speed rail, howeverthe TGV station is designed to connect other regions of France to the airport, rather than central Paris.[2]
In June 2000,SNCF,Réseau Ferré de France and Aéroports de Paris formed CDG-Express, agroupement d'intérêt économique, to develop a high-speed rail link fromParis toCharles de Gaulle Airport. It was proposed to open in 2006.[3][2]
In July 2008, a consortium ofVinci,Caisse des dépôts et consignations,Axa andKeolis was selected to finance, build and operate the line with a scheduled 2013 opening.[4] In 2011, the government abandoned the plan to have a consortium complete and operate the project.[2]
In 2014, the project was relaunched, with a 50:50joint venture betweenSNCF Reseau andParis Aéroport to build and manage the line.[5][6] Subsequently an updated DUP (Declaration of Public Utility) was granted and an government loan of € 1.7 billion was approved in 2018.[2]
Following this, a SNCF Réseau,Groupe ADP andCaisse des dépôts et consignations formed a group with equal shares of equity capital of around €450-500 million. The group adopted the CDG Express nomenclature in 2019.[7] In November 2018, the companyHello Paris, a Keolis andRATP Group joint venture, was selected to operate the line for 15 years from January 2024 with a fleet ofAlstom Coradia Liners.[8] €537 million would be spent to upgrade and improve RER B, improving reliability for Franciliens.[9]

Construction of the line began in 2018, with an initial completion date of 2023 for theParis 2024 Olympic and Paralympic Games. On 29 May 2019, transport ministerÉlisabeth Borne announced the CDG Express would be delayed to late 2025,[10] after the2024 Summer Olympics, in order to focus on other infrastructure works in the northern suburbs of Paris.[11][12]
Legal challenges further delayed construction, with work suspended by a court inMontreuil in 2020. In 2022, the Administrative Court of Appeal of Paris permitted work to continue.
Commissioning with opening to the public is currently scheduled for 28 March 2027.[1]
CDG Express is expected to offer a 20-minute non-stop ride every 15 minutes from 5am to midnight.[13][2] The new line is expected to take airline customers off RER B, making room for local passengers, and divert 15% of airport automobile trips to rail.[13]
CDG Express will use dedicated platforms at bothCharles de Gaulle Airport andGare de l'Est. Ticket prices are expected to be around €24.
CDG Express will connectCharles de Gaulle Airport toGare de l'Est in the10th arrondissement of Paris. Leaving Gare de l'Est, the CDG Express will use 1 kilometre (0.62 mi) of new tracks linking it to the RER B tracks exitingGare du Nord, before following RER B eastwards for 24 kilometres (15 mi) on tracks upgraded for 140 kilometres per hour (87 mph). After Villeparisis, the CDG Express will turn north on 8 kilometres (5.0 mi) of new tracks to follow theLGV Interconnexion Est high-speed line to the airport itself, with a 400 metres (1,300 ft) tunnel taking it to the existingAéroport Charles de Gaulle 2 TGV station.[2]

CDG Express will useCoradia Liner trains.[2]
Hello Paris ordered 6 four-car and 7 six-car trains fromAlstom in 2018 at a cost of €160 million. This order was transferred toConstrucciones y Auxiliar de Ferrocarriles (CAF) after Alstom purchasedBombardier Transportation. Trains will feature real-time flight information and luggage space.[2]
The first trains were completed in 2022, and some are being stored inStrasbourg pending the opening of the line.[2]
