Paris Métro Line 15


Paris Métro Line 15 is one of four lines of the Grand Paris Express. It is planned to open in phases from 2020 through 2030. It aims at creating a loop connecting Noisy–Champs station to Champigny, notably passing through Champigny-sur-Marne, Créteil, Villejuif, La Défense, Saint-Denis and Rosny-sous-Bois.
Conceived as a subterranean rail line equivalent in capacity to the Parisian métro, it will constitute a new relief line servicing the departments of Hauts-de-Seine, Val-de-Marne and Seine-Saint-Denis. It will enable direct transportation between the suburbs, bypassing Paris and thus avoiding transloading.
It will be the longest tunnel for passenger traffic in the world.

History

The configuration of line 15 is very similar to that of the Arc Express, proposed by the RATP in 2006. It was later included in the red line project of the Grand Paris public transportation network, introduced by French President Nicolas Sarkozy in 2009. In March 2013, the "New Grand Paris" project was announced by the Prime Minister at the time, Jean-Marc Ayrault. At this time, the line acquired its current line 15 naming.
Since August 2013, the New Grand Paris steering committee has met each trimester. The first public inquiry, focused on the southern section from Pont-de-Sèvres to Noisy–Champs, was held from October to mid-November, 2013.

Proposed timeline

In 2013, the government led by Ayrault proposed the following implementation timeline for the line 15 project:
