Grand Paris Express


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, plus extensions of existing Lines 11 and 14. A total of 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, 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 once a trimester. The first public inquiry, focused on the southern section of Line 15 from to Noisy–Champs, was held from October to mid-November, 2013. Work on line 15 began in 2015, with its first section scheduled to open around 2020 between Métro station and Noisy–Champs RER A station. This line was first proposed in the Orbival project, then integrated into the Arc Express.

Line 11 extension

In order to ensure better commuter service to the inner Northeastern suburbs, a six-station, eastbound extension of Line 11 is under construction from to Rosny-sous-Bois. The scheme was initially lobbied for by the local authorities of these suburbs, and was adopted during the 2007 review of the Île-de-France Transportation Plan. Work on the extension to Rosny – Bois-Perrier started in 2015 and it is expected to open by 2021. It will provide new connections with the RER E and the extended Île-de-France tramway Line 1, which it will better link to downtown Paris and the commuter hub of Châtelet–Les Halles.

Revisions in the Grand Paris Express Plan and possible automation

A revised plan for the proposed Grand Paris Express subway system was unveiled on March 6, 2013, and calls for a second extension of Line 11 to be built towards. The target opening date is 2030, but might be pushed back. Should the second extension be built, Line 11 will eventually be fully automated. Automatic train operation is not currently planned for the Rosny extension, although the RATP and STIF had considered the possibility of adding it later on.

Rolling stock

As of March 2013, it was expected that additional MP 14 stock will be used for line 11.

Line 14 extension

The automated Line 14 is being extended north from, with the primary aim of reducing overcrowding on line 13. The adopted solution connects both branches of line 13 to line 14, with stations at on the Asnières – Gennevilliers branch and on the Saint-Denis branch. An additional station will connect with the RER C station, and another with the Transilien Paris – Saint-Lazare lines at Pont-Cardinet, and the final one with the RER D at. Construction on the extension began in 2014, with an aim of completion by 2019. Completion was later delayed to mid-2020 after the tunnel works were stopped for a year by flooding from the water table.
There are also plans to extend line 14 south towards Orly Airport. The extension would travel southeastward from to, with a possible connection to Line 7's Villejuif branch.
When both extensions are complete, it is expected that Line 14 will eventually be merged into the proposed Grand Paris Express system.

Rolling stock

In February 2012 the STIF announced that with the two extensions planned, the brand new MP 14 class of rolling stock will replace the current MP 89CA stock on Line 14 in about 2020. This new stock would be in eight-car train formations, something not yet employed on the Métro but allowed by the length of all Line 14 stations, and the MP 89CA and MP 05 stock would be reassigned to other lines.

Line 15

Line 15 will be a high-capacity underground rail line, providing a new ring line around Paris in 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. The configuration of the line 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.
Line 15 is planned to open in phases from 2020 through 2030. It will create a loop connecting Noisy–Champs to Champigny, passing through Champigny-sur-Marne, Créteil, Villejuif, La Défense, Saint-Denis and Rosny-sous-Bois.

Proposed timeline

In 2013, the government led by Ayrault proposed this timeline for the line 15 project:
The proposed rolling stock for line 15 is a new automated design, using conventional steel wheel on steel rail technology and overhead electrification, with a width of.
The specifications of the trains travelling line 15 and their operation are as follows:
Line 16 is planned to open in 2023.
Line 17 is planned to open in phases between 2025 and 2030.
