Since August 2013, the New Grand Paris steering committee has met each trimester.^[2] The first public inquiry, focused on the southern section from {{pms|Pont de Sèvres}} to Noisy – Champs, was held from October to mid-November, 2013.^[3] Work on line 15 began in 2015, with its first section scheduled to open around 2020 between {{pms|Pont de Sèvres}} 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, {{convert|5|km}} eastbound extension of Line 11 is under construction from {{pms|Mairie des Lilas}} to Rosny-sous-Bois . The scheme was initially proposed by local authorities, and was adopted during the 2007 review of the Ile-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 called for a second extension of Line 11 to be built towards Noisy-Champs. The target opening date is 2030, although it is unclear if this goal will be attainable. Should the second extension be built, Line 11 will eventually be fully automated.^[4] 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 {{pms|Saint-Lazare}}, with the primary aim of reducing overcrowding on line 13.^[5] The adopted solution connects both branches of line 13 to line 14, with stations at {{pms|Porte de Clichy}} on the Asnières – Gennevilliers branch and {{pms|Mairie de Saint-Ouen}} on the Saint-Denis branch. An additional station will connect with the {{prs|Saint-Ouen}} RER C station, and another with the Transilien Paris – Saint-Lazare lines at Pont-Cardinet, and the final one with the RER D at {{prs|Stade de France – Saint-Denis}}. An infill station between Saint-Lazare and Pont-Cardinet may also be built, which would provide line 14 with a connection to line 2 at {{pms|Rome}}. Construction on the extension began in 2014, with an aim of completion by 2019.^[6]

There are also plans to extend line 14 south towards Orly Airport. The extension would travel southeastward from {{pms|Olympiades}} to {{pms|Maison Blanche}}, 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.^[7]

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 (and upcoming MP 05) stock on Line 14 in about 2020. This new stock would be in eight-car train formations, something not yet employed on the Métro, and would allow for the MP 89CA and MP 05 stock to be reassigned to other lines.^[8]

Line 15

Line 15 is planned to open in phases from 2020 through 2030.^[12] It will create a loop connecting {{pms|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:^[13][14]

• 2014: Public inquiry on the eastern section from Saint-Denis Pleyel to Champigny Centre.
• Early-2015: Groundbreaking for the southern section between Pont-de-Sèvres and Noisy - Champs.
• 2020: Groundbreaking of the section from Pont-de-Sèvres to Nanterre and from Saint-Denis Pleyel to Rosny-Bois-Perrier on the northern section.
• 2022: Southern section from Pont-de-Sèvres to Noisy - Champs opens.
• Early 2025: Segments from Pont-de-Sèvres to Nanterre and from Saint-Denis Pleyel to Rosny-Bois-Perrier of the northern section put into service.
• 2025: Groundbreaking of the segment from Nanterre to Saint-Denis Pleyel via La Défense-Grande-Arche of the northern section.
• Early 2030: Segment from Nanterre to Saint-Denis Pleyel via La Défense-Grande-Arche of the northern section put into service.
• End of 2030: Northern section from Rosny to Champigny completed.

Rolling stock

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 {{convert|2.80|m}}.

The specifications of the trains travelling line 15 and their operation are as follows:^[15][16]

• Train width: {{convert|2.80|m}} minimum
• Train length: {{convert|108|m}}, made up of 6 cars with full-open interior gangways
• Train capacity: 960 passengers (at 4 passengers per m²)
• Bearings: iron
• Electric traction current: 1500 volt direct current via pantograph and contact wires^[17]
• Operation: Fully automated
• Maximum speed: {{convert|120|km/h}}^[18]
• Operating speed: {{convert|55|km/h}}^[18]
• Theoretical morning rush hour throughput: 34 560 passengers per hour^[19]
• Average interval: 3 to 4 minutes^[18]
• Minimum interval: 2 minutes^[18]

Lines 16 and 17

Rolling stock

The proposed rolling stock for lines 16 and 17 is a new automated design with a width of {{convert|2.80|m}}, using conventional steel wheel on steel rail technology and overhead electrification.

Line 18

Rolling stock

The proposed rolling stock for line 18 is a new automated design with a width of {{convert|2.45|m}}, using conventional steel wheel on steel rail technology and third rail electrification.
