The LGV Interconnexion Est is a French high-speed rail line that connects the LGV Nord, LGV Est, LGV Sud-Est and LGV Atlantique through the suburbs of Paris. Opened in 1994, it consists of three branches, which begin at Coubert:
- west branch: towards Paris and western France, terminating at Valenton at the Grande Ceinture line, which connects to the LGV Atlantique at Massy TGV
- north branch: towards northern France, London and Brussels, joining the LGV Nord at Vémars
- south branch: towards southeastern France, joining the LGV Sud-Est at Moisenay
The south and west branches are now shared with the LGV Sud-Est line.
Maximum line-speed throughout is 300 km/h (186 mph).
