The LGV Interconnexion Est is a French high-speed railway that links the LGV Nord, LGV Est, LGV Sud-Est, and LGV Atlantique networks via the suburbs surrounding Paris. Commissioned in 1994, it branches out from Coubert into three directions:
- western branch: extends towards Paris and western regions of France, terminating at Valenton on the Grande Ceinture line, providing connection to the LGV Atlantique at Massy TGV station
- northern branch: heads to northern France, as well as London and Brussels, by merging with the LGV Nord at Vémars
- southern branch: routes towards southeastern France, joining the LGV Sud-Est line at Moisenay
Both the southern and western branches share tracks with the LGV Sud-Est. The infrastructure allows trains to travel at speeds reaching 300 km/h (186 mph).
Route
Beginning at the southern point of connection with the LGV Sud-Est at Coubert junction, the line proceeds northeastward. Near Tournan-en-Brie, it intersects with the Paris-Coulommiers, Seine-et-Marne railway. It serves the important transfer station Marne-la-Vallée – Chessy TGV, which offers access to the RER A and Disneyland Paris. Close to Claye-Souilly, two connecting links currently under construction will establish connections to the LGV Est. The route also includes service to the significant transport interchange at Aéroport Charles de Gaulle 2 TGV, linking with the RER B and air travel facilities. Shortly beyond this point, it merges with the LGV Nord at the junction near Vémars.

Expansion
- Plans are being evaluated for constructing a suburban railway alongside the LGV between Villeparisis and Vémars, aiming to enhance Roissy airport access from Paris as an alternative to the CDG Express, or to establish a western route connecting Creil, Meaux, Marne-la-Vallée, and Melun.
- Additional proposals consider supplementing the Interconnexion Est with an LGV Interconnexion Sud or Ouest.
- In November 2010, formal feasibility studies were initiated by RFF for a connection from Interconnexion Est towards the Paris - Creil - Amiens corridor.
