Grand Paris Express topic's main category railway network
Grand Paris Express is a group of new rapid transit lines being built in the Île-de-France region of France. The project comprises four new lines for Paris Métro, plus extensions of existing Lines 11 and 14. A total of 200 kilometres (120 mi) of new track and 68 new stations are to be added, serving a projected 2 million passengers a day.The new lines were originally indexed by colour (Red Line, Pink Line, Green Line), but this changed in 2013 to continue the numbering convention that the RATP uses. The new lines are therefore now known as 15, 16, 17 and 18. They are planned to open in stages through 2030.Since August 2013, the New Grand Paris steering committee has met quarterly. The first public inquiry, focused on the southern section of Line 15 from Pont de Sèvres to Noisy–Champs, was held from October to mid-November 2013. Work on line 15 began in 2015. Its first section between Pont de Sèvres Métro station and Noisy–Champs RER A station was scheduled at that time to open around 2020, but this has now been pushed back to 2025. This line was first proposed in the Orbival project, then integrated into the Arc Express.
