TheGrand Paris Express (French:[ɡʁɑ̃paʁiɛkspʁɛs];GPE) is a project consisting of new rapid transit lines and the extension of existing lines being built in theÎle-de-France region of France. The project comprises four new lines for theParis Métro, plus extensions of the existing Lines11 and14. A total of 200 kilometres (120 mi) of new tracks and 68 new stations are to be added, serving a projected 2 million passengers a day.^[5]

The new lines were originally indexed by colour (Red Line, Pink Line, Green Line, Blue Line), but this was changed in 2013 to continue the numbering convention that theRATP uses. They are therefore now known asLine 15,Line 16,Line 17 andLine 18.^[6] The constructed lines are planned to open in stages, starting with the Line 14 extension in June 2024, until 2031.^[7]

Since August 2013, the New Grand Paris steering committee has met quarterly.^[8] The first public inquiry, focused on the southern section of Line 15 fromPont de Sèvres toNoisy–Champs, was held from October to mid-November 2013.^[9] Work on Line 15 began in 2015. Its first section betweenPont de Sèvres Métro station and Noisy–ChampsRER A station was scheduled at that time to open around 2020, but this has now been pushed back to late 2026.^[10] This line was first proposed in theOrbival project, then integrated into theArc Express.

A six-station 5.4-kilometre (3.4 mi) eastern extension of Line 11 from Mairie des Lilas toRosny-sous-Bois, not considered part of the Grand Paris Express project, improves commuter service to the inner northeastern suburbs. 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 toRosny – Bois-Perrier started in 2015^[11] and opened on 13 June 2024.^[12] It provides connections with theRER E and withÎle-de-France tramway Line 1, which better links central Paris with the commuter hub ofChâtelet–Les Halles.

A revised plan for the proposed Grand Paris Express subway system unveiled on 6 March 2013 calls for a second extension of Line 11 to be built towardsNoisy–Champs. This second extension would be considered part of the Grand Paris Express project. Its target opening date was 2030, but might be pushed back. Should the second extension be built, Line 11 will eventually be fully automated.^[13] Automatic train operation was not implemented with the Rosny extension, although the RATP and STIF considered the possibility of adding it later on.

Line 11 was the first metro line converted to rubber-tyred pneumatic operation, and its first set of rubber-tyred rolling stock was theMP 55, which operated from October 1956 through January 1999. They were then replaced by refurbishedMP 59 stock from Line 4. The MP 55 stock consisted of 4 carriages, as did the replacement MP 59 stock. OneMP 73 ofline 6 was in service on the 11 as well.

Île-de-France Mobilités planned to replace the aging fleet of Line 11 withMP 14 series trains around the time of the opening of the extension toRosny-sous-Bois. The new trains are driver-operated as the MP 59 fleet was, but they are 5 cars long and have open gangways.^[14][15]An initial 20 trains were ordered in February 2018, with an additional 19 trains ordered in July 2021.^[16] Production began in late 2020, and testing in summer 2021.^[16]

The first newMP 14 CC (manual transit) were deployed in June 2023, with four new trains entering service each Tuesday to replace fourMP 59 transferred to the Rosny-sous-Bois workshop on Monday nights to be retired. Twenty newMP 14-manual transit were deployed by summer 2023, with an additional nineteen new trains deployed in spring 2024 to serve the extension toRosny–Bois-Perrier.^[17] The ceremonial final runs of the MP 59 took place on 23 May 2024, with #'s 6069, 6073 and 6087 being the final three to be withdrawn.[1]

The automatedLine 14 was extended north fromSaint-Lazare toMairie de Saint-Ouen, with the primary aim of reducing overcrowding onLine 13.^[18] The adopted solution connects both branches of Line 13 to Line 14, with stations atPorte de Clichy on the Asnières – Gennevilliers branch andMairie de Saint-Ouen on the Saint-Denis branch. An additional station connects with theSaint-OuenRER C station, and another with theTransilien Paris-Saint-Lazare lines atPont Cardinet, and the final one with theRER D atSaint-Denis–Pleyel. Construction on the extension began in 2014, with an aim of completion by 2019.^[19] Completion was later pushed back to 2020 after flooding from the water table stopped the tunnel works for a year. The COVID-19 pandemic then further delayed the opening to December 2020.^[20] The extension opened on 24 June 2024, just a month before the2024 Summer Olympics.^[21]

Line 14 was also extended south fromOlympiades towardsOrly Airport. The extension travels southeastward from Olympiades toMaison Blanche, interchanging withLine 7'sVillejuif branch, and opened on 24 June 2024 (again, just a month before the 2024 Summer Olympics).^[21]

With both extensions complete, it is expected that Line 14 will eventually be merged into the proposed Grand Paris Express system.^[22]

In February 2012 the STIF announced that with the two extensions planned, the brand newMP 14 class of rolling stock would replace theMP89 CA andMP 05 stock on Line 14 starting from 2020. This new stock is in eight-car train formations, longer than previously employed anywhere on the Paris Métro but which the length of all Line 14 stations was planned for. The previous MP 89 CA and MP 05 stock was then reassigned to the newly automated line 4, alongside some 6-car new MP 14s. They replaced its manually drivenMP 89 CC rolling stock, which was refurbished before going to line 6 to replace the agingMP 73 rolling stock.^[23]

Line 15 will be a high-capacity underground rail line, providing a new ring line around Paris in the departments ofHauts-de-Seine, Val-de-Marne andSeine-Saint-Denis. It will enable direct journeys between the suburbs, bypassing central Paris.^[24][25] The configuration of the line is very similar to that of theArc Express, proposed by theRATP in 2006. It was later included in the red line project of the Grand Paris public transportation network, introduced by French PresidentNicolas 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.^[26]

Line 15 is planned to open in phases from 2026 through 2031.^[27] It will create a loop connecting Noisy–Champs to Champigny, passing throughChampigny-sur-Marne,Créteil,Villejuif,La Défense,Saint-Denis andRosny-sous-Bois.

On 22 February 2018, a new timeline is announced by Prime ministerÉdouard Philippe:^[28]

• During 2014: Public inquiry on the eastern section from Saint-Denis–Pleyel to Champigny Centre.
• Early 2015: Groundbreaking of the southern section spanning Pont-de-Sèvres to Noisy–Champs.
• 2024, postponed to 2025 in September 2018: Southern section from Pont de Sèvres to Noisy–Champs put into service.
• 2030: western section from Pont de Sèvres to Saint-Denis–Pleyel and eastern section from Saint-Denis–Pleyel to Champigny Centre put into service.

In 2013, the government led by Ayrault proposed this timeline for the line 15 project:^[29][30]

• 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.

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 2.80 metres (9 ft 2 in). Alstom has been chosen to build these trains. The names of the trains are the Alstom MetropolisMR3V/MR6V (MR6V (6-car variant for line 15) and MR3V (3-car variant for lines 16 and 17)).^[31]
