'''Paris Métro Line 11''' ([[French language|French]]: ''Ligne 11 du métro de Paris'') is one of the sixteen lines of the [[Paris Métro]]. It links {{stn|Châtelet}} to {{stn|Rosny–Bois-Perrier}} in the northeastern suburbs. This line was one of the last to be put into service in 1935; it was then intended to replace the [[Belleville funicular tramway]], which closed in 1924. The line is 11.7 km (7.3 mi) in length with 19 stations. 

Before its 2024 extension, it was one of the least used lines, with less than forty million passengers in 2023. The [[RATP Group|RATP]] expects thirty-one million more in 2025, with this extension to four major municipalities in [[Seine-Saint-Denis]].

During the 1950s and 1960s, the line was an experimental line for innovations developed by the RATP. As such, in 1956, it was the first metro line in the world to be equipped with [[Rubber-tyred metro|rubber tyres]]; it was also equipped with a centralised control station and [[automatic train operation]] in 1967, which was used for the first time on the Paris network. It was extended from {{stn|Mairie des Lilas}} to {{stn|Rosny-Bois-Perrier}} on 13 June 2024, almost doubling its length and adding six stations. A proposed extension to {{stn|Noisy–Champs}} as part of the [[Grand Paris Express]] project has been postponed indefinitely.

==History==
{{main|Belleville funicular tramway}}
[[File:Metro Paris ligne 11 - Telegraphe - Escaliers.jpg|thumb|upright=0.7|The steep stairs of ''[[Télégraphe station|Télégraphe]]'' station]]
The supplementary network approved in 1909 provided for a short line linking the [[Place de la République]] to the Porte des Lilas.{{sfn|Lamming|2015 |p=99}} This section was declared to be of public utility by the law of 30 March 1910 but was not built.{{sfn|Lamming|2015 |p=114}}

On 29 December 1922,{{sfn|Tricoire|1999|p=292}} the Paris City Council relaunched the project and voted to create a line to better serve the working-class neighbourhoods of north-east Paris by connecting the Belleville district to the Châtelet district in the city centre. This line was intended to replace the [[Belleville funicular tramway]] and the bus lines in the north-east of the capital. It would connect [[Châtelet station]] (on Avenue Victoria) to the Porte des Lilas via the Place de la République. 

The line was originally intended to follow Rue de Belleville for its entire length, but a change in the route ultimately allowed it to serve [[Place des Fêtes station]] in order to provide a connection with [[Paris Métro Line 7bis|Line 7]] (on its then route), at the cost of passing under buildings for around {{cvt|800|m}}.{{sfn|Lamming|2015|p=115}} Similarly, it was planned to connect {{stn|République}} and {{stn|Hôtel de Ville}} stations by making the route as short as possible, with two stations under the narrow Rue du Temple, but the final route runs further west via {{stn|Arts et Métiers}} and the new [[Rambuteau station]].{{sfn|Ovenden|Pepinster|Pontremoli|2015|p=68}}

The section from Place de la République to Avenue Victoria was declared to be of public utility by a decree of 14 May 1925.{{sfn|Lamming|2015 |p=114}} Work began in September 1931,{{sfn|Tricoire|1999|p=293}} with the exception of the structure under the Place de la République, which had been built at the same time as lines 8 and 9.{{sfn|Lamming|2015 |p=114}} It took place in fairly difficult conditions, as the line passed under narrow streets and the foundations of some buildings. The passages under the Coteaux collector, the [[Canal Saint-Martin|Saint-Martin canal]] and above a tunnel on the [[Chemin de fer de Petite Ceinture|Petite Ceinture]] were also tricky. The construction of the {{stn|Jourdain}} and [[Télégraphe station]]s also proved difficult, given their great depth, {{cvt|20|m}}, and the fairly unstable nature of the ground, made up of inconsistent green clay. To the south, near the [[Seine]], the line was built in alluvial soil containing a [[water table]]. Despite these difficulties, the infrastructure was handed over to the [[Compagnie du chemin de fer métropolitain de Paris]] (CMP) on 3 May 1934 after two and a half years of work.

The last line of the network created before [[Paris Métro Line 14 (1937–1976)|old line 14]], it had to pass under all the other metro lines, with the exception of part of [[Paris Métro Line 3|line 3]], which became [[Paris Métro Line 3bis|3 bis]], at Porte des Lilas. Line 11 was inaugurated on 28 April 1935. On this occasion, {{stn|Châtelet}} (lines 1 and 4) and ''Pont Notre-Dame - Pont au Change'' ([[Paris Métro Line 7|line 7]]) stations were connected by a corridor to the line 11 station and united under the name Châtelet in 1934.{{sfn|Lamming|2015 |p=115}} The new line was {{cvt|5.5|km}}-long and had twelve stations, all [[Vault (architecture)|vaulted]], with a platform length of {{cvt|75|m}}. The line was then served by twenty-two four-car trains.{{sfn|Robert|1983|pp=127-128}}

A first extension to ''Fort de Rosny'' was declared to be of public utility in 1929. But it was necessary to wait until 7 February 1937{{sfn|Tricoire|1999|p=294}} to see the line extended by a single station to {{stn|Mairie des Lilas}}, the only station in this town, which became the 13th station and terminus of the line. The continuation of this extension was interrupted by the Second World War. During the war, on 12 May 1944, the German army requisitioned the line to establish its underground weapons workshops and closed the line to traffic. Indeed, built at great depth, it was out of reach of the bombs that hit the city. After the [[Liberation of France|Liberation]], the operation of the metro gradually resumed with difficulty because of the shortage of coal and therefore of electric traction current, but line 11 was the only one that remained closed as a result of serious deterioration of its infrastructure, including the removal of part of the tracks by the Germans. It was necessary to wait until 5 March 1945 for the reopening to the public after essential refurbishment.{{sfn|Robert|1983|pp=142-143}}

===The experiment of the metro line on rubber tyres===
[[File:Metro de Paris - Ligne 11 - MP 59 - Pneus.jpg|thumb|MP 59 tyre-mounted equipment on line 11]]
{{main|Rubber-tyred metro|MP 55}}
Experimentation with rubber-tyred rail vehicles dates back to the 1930s. Rubber-tyred equipment has the advantage of better acceleration and deceleration, which in turn increases the throughput of a line, which is particularly noticeable on a metro line with frequent and closely spaced stops. The technology also reduces rolling noise and vibrations.

In 1950, the first tyres with metal reinforcement appeared on the market, capable of supporting a load of {{cvt|4|tonne}} with wheels with a diameter of less than {{cvt|1|m}}. The [[RATP Group|RATP]] conducted a test campaign in 1951 on the shuttle track, with a prototype, the [[MP 51]]. From 13 April 1952, the public was admitted every afternoon to take the shuttle, which continued its tests until 31 May 1956.{{sfn|Robert|1983|p=152}}

The tests proving conclusive, it was then decided to use this technology on line 11, which had the particularity of being quite short, winding and very steep, in order to test this new technology on a full-scale secondary line before generalising it on the network, which the RATP planned.

The line was converted to run on rubber tyres from 1954 to 1956. The work was mainly carried out at night so as not to disrupt the operation of the line; however, the service was reduced by one hour in the evening. Four methods of laying of the tyre tracks were tried, responding to two opposing concepts. One consisted of limiting as much as possible the modification work to be carried out, thus keeping the ballast supporting the track as it was. The other consisted of taking advantage of the fact that the elasticity of the track support was no longer useful, it being now supported by the tyres, which made it possible to eliminate the regular interventions to re-tamp the ballast which were necessary to ensure correct track geometry.

[[File:MP 59 ligne 11 Chatelet 02.ogv|thumb|Video of a [[MP 59]] set at the ''{{stn|Châtelet}}'' terminus heading towards the turnback facility]]
The ''T-layout'' consisted of bolting [[Lophira alata|azobé]] bearing parts onto the sleeper heads placed on the ballast; the ''D-layout'' fixed the bearing parts onto concrete blocks or blocks cast onto the foundation raft; the I-layout was similar but with injection of cement mortar into the ballast and the S-layout was adopted in stations, with the azobé bearing parts resting on concrete walls cast onto the foundation raft. This latter arrangement improved the appearance and maintenance of the track and reduced the severity of accidents involving people (accidental falls onto the track or suicide) by the presence of a central pit.{{sfn|Sirand-Pugnet|1997|pp=48-51}}

The line was equipped with the new MP 55 sets from 1 October 1956 to November 1957, replacing the old Sprague sets, the last of which left the line for good on 11 October 1957.{{sfn|Sirand-Pugnet|1997|p=54}} The first rubber-tyred train was inaugurated on 8 November 1956<ref>{{cite web|url=http://www.ina.fr/video/CAF89036916/ |publisher=[[Institut national de l'audiovisuel]] |title= Inauguration du métro sur pneus |date=8 November 1956 |type=excerpt from [[Office de Radiodiffusion Télévision Française|ORTF]] television news|access-date=24 September 2024|language=fr}}</ref>{{sfn|Tricoire|1999|p=96|loc=|id=}} and the new operation of line 11 began on 13 November 1956, the first day of commercial service. The old sets on the line were then gradually transferred as new sets were delivered, in order to strengthen the service on [[Paris Métro Line 2|line 2]], the trains of which were increased from four to five cars in June 1958. The surplus equipment allowed twenty-nine motor cars and thirty-seven trailers to be removed from service, most of which dated back to 1908 and 1909.{{sfn|Robert|1983|p=154}}

In 1967, the line was equipped with a centralised control centre and automated train operation, which was used for the first time on the Parisian network. The MP 55 sets were gradually withdrawn from 1982 to 1999 and replaced by [[MP 59]] sets, from [[Paris Métro Line 2|line 4]].{{sfn|Tricoire|1999|p=97}} Line 11 had not seen any significant development since that date until the commissioning of the new centralised control centre at Bagnolet on 1 June 2021.<ref name="PCC2021">{{cite news|access-date=24 September 2024|language=fr|date=9 July 2021 |title=19 MP14 supplémentaires |url=http://transportparis.canalblog.com/archives/2021/07/09/39051965.html |newspaper=Transport Paris}}</ref>

The design of the rolling stock and the steep gradient of the route make it one of the hottest lines on the Paris network, along with line 4.<ref>{{cite web|access-date=24 September 2024|language=fr |date=8 July 2010 |title=Y a-t-il un coup de chaud dans le métro parisien? |url=https://www.20minutes.fr/article/584281/Societe-Y-a-t-il-un-coup-de-chaud-dans-le-metro-parisien.php |archive-url=https://web.archive.org/web/20100710091351/https://www.20minutes.fr/article/584281/Societe-Y-a-t-il-un-coup-de-chaud-dans-le-metro-parisien.php|archive-date=10 July 2010|publisher=20 minutes}}</ref>

As part of the extension of the line from Mairie des Lilas to Rosny-Bois-Perrier, most of the stations underwent renovation and adaptation work, including the creation of new access points. The rear yard at Châtelet, which was too short to accommodate the future five-car [[MP 14 (Paris Métro)|MP 14]] metro trains, had to be extended in a restricted space under buildings.<ref>{{cite web|access-date=24 September 2024|language=fr |date=13 November 2019 |title=Métro: quatre prolongements qui avancent (quand même) |url=http://transportparis.canalblog.com/archives/2019/11/13/37773823.html |newspaper=Transport Paris}}</ref> To carry out this exceptional work, it was necessary to temporarily terminate the line at Hôtel de Ville.

The municipalities of [[Romainville]], [[Noisy-le-Sec]], [[Montreuil, Seine-Saint-Denis|Montreuil]] and [[Rosny-sous-Bois]], as well as the council of [[Seine-Saint-Denis]], had proposed a project to extend the line from {{stn|Mairie des Lilas}} to {{stn|Rosny-Bois-Perrier}}, an additional {{cvt|6|km}} to be covered in 12 minutes, with the full journey taking, according to the RATP, 24 minutes from Châtelet to Rosny-Bois-Perrier, compared to 55 minutes at the time.<ref name="IDFMA86"/><ref>{{cite web|url=http://www.ville-leslilas.fr/infos/projets/page_projets.php?news=dossiers&id=11 |title=Prolongement du métro ligne 11: le ripage du tunnel à Rosny, une étape clé des travaux|trans-title=Extension of metro line 11: the tunnel shift in Rosny, a key stage of the works|publisher=[[Île-de-France Mobilités]]|date=10 August 2018|access-date=25 September 2024|language=fr}}</ref> This involved implementing in a new form a project that was over a century old.{{efn|In 1900, the Romainville municipal council unanimously called for the extension of the metro to this commune}}

This extension allows an interconnection with the [[RER E]], as well as service from Paris, by metro, to the Rosny 2 shopping centre. One of the new stations, {{stn|Romainville–Carnot}}, also provides an interconnection with the future extension of the [[Île-de-France tramway Line 1|T1 tramway]] to the south, the new terminus of which would be at Val de Fontenay. The [[Paris Métro Line 15|metro line 15]] east project, which will open after the extension of line 11, will also have a station at Rosny-Bois-Perrier, eventually allowing an additional connection at this station.<ref>{{cite web|access-date=25 September 2024|language=fr |date=6 October 2016 |title=Avis favorable et unanime pour la ligne 15 est |url=https://www.societedugrandparis.fr/actualite/avis-favorable-et-unanime-pour-la-ligne-15-est |archive-url=https://web.archive.org/web/20161220205050/https://www.societedugrandparis.fr/actualite/avis-favorable-et-unanime-pour-la-ligne-15-est|archive-date=20 December 2016|publisher=Société du Grand Paris}}</ref> All the new stations would be accessible to people with reduced mobility and new rolling stock, the [[MP 14 (Paris Métro)|MP 14]], would be put into service on this occasion,<ref>{{cite web|access-date=25 September 2024|language=fr |date=30 May 2016 |title=Découvrez à quoi ressembleront les nouvelles rames de la Ligne 14 du métro à Paris |url=https://www.huffingtonpost.fr/2016/05/30/decouvrez-a-quoi-ressembleront-les-nouvelles-rames-de-la-ligne-1/ |archive-url=https://web.archive.org/web/20161220103034/https://www.huffingtonpost.fr/2016/05/30/decouvrez-a-quoi-ressembleront-les-nouvelles-rames-de-la-ligne-1/|archive-date=20 December 2016|publisher=Huffington Post France}}</ref> in a five-car layout (instead of four since the beginning).

According to RATP studies financed by the 2000-2006 State-Region project contract (''Contrat de plan État-région'', CPER), this extension would increase the number of passengers on line 11 by 68,700 each working day.<ref>{{cite web|access-date=25 September 2024|language=fr|url=http://www.ville-leslilas.fr/infos/projets/images/ligne11_2.pdf |archive-url=https://web.archive.org/web/20081115003301/http://www.ville-leslilas.fr/infos/projets/images/ligne11_2.pdf|archive-date=15 November 2008|title=La Ligne 11, aujourd'hui et demain|publisher=Municipality of [[Les Lilas]]}}</ref> The public consultation launched in 2010 estimated the cost of the project at €820m, to which should be added €140m for the renewal of rolling stock and around €100m for the renovation of existing stations.<ref name="Prolongement_cout">{{cite web|access-date=25 September 2024|language=fr |title=Coût et financement |url=http://www.prolongementligne11est.fr/Cout-et-financement |archive-url=https://web.archive.org/web/20110203080052/http://www.prolongementligne11est.fr/Cout-et-financement|archive-date=3 February 2011 |publisher=Prolongementligne11est.fr}}</ref> The agreement approved by the STIF on 7 October 2015 set the financing requirement at €1,084m ([[Île-de-France]] region €500.3m; SGP €305.3m; State, €214.4m; Seine-Saint-Denis €64m) for the extension, to which must be added €214m (RATP €73m; Paris City €61m; Region €56m; State €24m) for the adaptation of existing stations and €151m by Île-de-France Mobilités for the renewal of rolling stock.<ref name="Prolongement_cout2015">{{cite web|access-date=25 September 2024|language=fr |title=Un investissement de près de 1,3 milliard d'euros |url=http://prolongementligne11est.fr/les-acteurs/ |publisher=Prolongementligne11est.fr}}</ref>

The Region included this project in the Île-de-France Region Master Plan (''Schéma directeur de la région Île-de-France'', SDRIF) adopted by the Île-de-France Regional Council on 25 September 2008. Initially, the SDRIF planned a phasing, with a first extension to {{stn|Montreuil–Hôpital}} between 2007 and 2013, then a second to Rosny-Bois-Perrier between 2014 and 2020.

[[File:Carte Métro Paris Ligne 11 (2024).svg|thumb|upright=2|Plan of the line after the extension to Rosny]]
The STIF Council approved the results of the consultation on 9 February 2011. Two trends clearly emerged: route 2 was preferred, because it would allow the opening up of the Londeau district in Noisy-le-Sec and would serve two high schools as well as the Domus and Rosny 2 shopping centres in Rosny-sous-Bois. It would also promote the development of the "concerted development zones" (''zone d'aménagement concerté'', ZACs) in the sector. The studies would therefore focus exclusively on this route. Furthermore, elected officials and residents were resolutely opposed to the phasing of the project: as a result, the STIF planned to carry out the work in a single stage.

As part of the extension, existing stations were developed, including the creation of new access points. The ''Mairie des Lilas'' and ''Porte des Lilas'' stations were equipped with lifts to provide access for people with reduced mobility; thus, all stations on line 11 between Porte des Lilas and Rosny-Bois-Perrier are now accessible.<ref>{{cite web|access-date=29 September 2024|language=fr |title=L'adaptation et la modernisation des stations {{!}} Prolongement Ligne 11 Est |url=http://prolongementligne11est.fr/ladaptation-et-la-modernisation-des-stations/ |publisher=prolongementligne11est.fr}}</ref>

At the foot of the future [[Serge Gainsbourg station]], a work pit was shown to elected officials at the end of May 2016.

The excavation of the first lot—{{cvt|3|km}} of tunnel, a {{cvt|200|m}}-long covered trench and earthworks as well as the installation of diaphragm walls and shafts for the subsequent construction of four metro stations—was awarded to a group led by [[Implenia]] in association with partners in a consortium comprising: NGE, Demathieu Bard and Pizzarotti. The work was due to begin in October 2016.

==Rolling stock==
[[File:MP 59 n°6080 Place des Fêtes.jpg|thumb|left|An [[MP 59]]-trainset, this model was fully retired from the line on June 12, 2024.]]
[[File:MP 14 - Ligne 11 - Châtelet - 01.06.2023.jpg|thumb|left|An [[MP 14 (Paris Métro)|MP 14 CC]]-trainset, which entered on service on June 1, 2023.]]

Being the first metro line to be converted to rubber-tyred pneumatic operation, the first set of rubber-tyred rolling stock to be in service on Line 11 was the [[MP 55]], which operated from October 1956 through January 1999. They were then replaced by refurbished [[MP 59]] stock from Line 4. The MP 55 stock consisted of 4 carriages, as well as the current MP 59 stock. One [[MP 73]] of [[Paris Métro Line 6|line 6]] is in service on the 11 as well.

The plan, according to [[Île-de-France Mobilités]], was to replace the fleet of Line 11 with the {{nobr|[[MP 14 (Paris Métro)|MP 14]]}} series, around the time when the extension to [[Rosny–Bois-Perrier station|Rosny-sous-Bois]] opened. Although the new trains will be driver-operated in the same method as the current fleet, they will be 5 cars long, and have open gangways.<ref name="stif_enquete_publique">Press release: [http://www.stif.org/IMG/pdf/13022013_-_CP_Conseil_STIF_-_Prolongement_ligne_11.pdf "Le prolongement de la ligne 11 du métro à Rosny-Bois-Perrier à l’enquête publique en 2013"], STIF, 13 February 2013</ref><ref>{{cite web|url=http://beta.leparisien.fr/info-paris-ile-de-france-oise/transports/le-metro-change-de-couleur-11-12-2018-7965513.php|title=Le métro parisien passe au bleu|website=Le Parisien|date=11 December 2018|first=Jila|last=Varoquier|access-date=12 December 2018|language=fr}}</ref>

==Future==
A revised plan for the proposed [[Grand Paris Express]] project was unveiled on 6 March 2013. The revisions call for a second extension of Line 11 towards Noisy-Champs, considered a part of the Grand Paris Express project, by 2030, although it is unclear if this goal will be attainable. Should the second extension commence, it is slated to come with a full automation of Line 11.<ref>[http://www.lesechos.fr/06/03/2013/lesechos.fr/0202626990936_-nouveau-grand-paris----l-etat-engage-27-milliards-pour-le-metro-parisien.htm Nouveau Grand Paris» : l'Etat engage 27 milliards pour le métro parisien],  ''Les Echos'', 3 June 2013 (In French)</ref> Automation was not implemented with the Rosny extension, though the RATP and STIF had considered the possibility of automating the line later on.

==Tourism==
Line 11 passes near several places of interest :
*The [[Hôtel de Ville, Paris|Hôtel de Ville]] (City Hall) of Paris.
*The [[Centre Georges Pompidou]] accommodating the [[Musée National d'Art Moderne|Paris Museum of Modern Art]].
*The [[Conservatoire National des Arts et Métiers]] (engineering school).
