RATP Group in the context of "Paris Métro Line 11"

The Paris Métro, short for Métropolitain, is a rapid transit system serving the Paris metropolitan area in France. A symbol of the city, it is known for its density within the capital's territorial limits, as well as its uniform architecture and historical entrances influenced by Art Nouveau. The system is 245.6 kilometres (152.6 mi) long, mostly underground, as well as its 321 stations of which 61 allow the riders to transfer between the sixteen lines (with an additional four under construction and one in project), all numbered 1 to 14, with two extra branches, 3bis and 7bis, named such as they are former parts of Lines 3 and 7 respectively. Three of these lines (1, 4 and 14) are fully automated, and the additional four are also planned as such. Lines are identified on maps by an individual number and an associated specific colour, all part of an official palette, with the traveling direction indicated by the terminus, the last stop on each line. All trains travel from one end of the line to the other, serving every station along the way. The Paris Métro is operated by the Régie autonome des transports parisiens (RATP), which also operates part of the RER (commuter standard train) network, most of the Francilian light rail lines and many bus routes around and within Paris itself.

It is the second-busiest metro system in Europe, as well as the twelfth-busiest in the world. It carried 1.476 billion passengers in 2024, roughly 4.04 million passengers a day, which makes it the most used public transport system in Paris. It is one of the densest metro systems in the world, with 244 stations within the 105.4 km (41 sq mi) of the City of Paris. Châtelet–Les Halles, with five Métro and three RER commuter rail lines, is one of the world's largest metro stations. The system generally has poor accessibility due to its old age (established 125 years ago) and because most of the current infrastructure was built before accessibility standards emerged, with few stations retrofitted since. On the flip side, all new infrastructure and rolling stock meets current accessiblity standards, including extensions of historic lines.

The Grand Paris Express (French: [ɡʁɑ̃ paʁi ɛkspʁɛs]; GPE) is a project consisting of new rapid transit lines and the extension of existing lines being built in the Île-de-France region of France. The project comprises four new lines for the Paris Métro, plus extensions of the existing Lines 11 and 14. 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.

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 the RATP uses. They are therefore now known as Line 15, Line 16, Line 17 and Line 18. The constructed lines are planned to open in stages, starting with the Line 14 extension in June 2024, until 2031.

The Réseau Express Régional (French pronunciation: [ʁezo ɛkspʁɛs ʁeʒjɔnal]; English: Regional Express Network), commonly abbreviated RER (pronounced [ɛʁəɛʁ]), is a hybrid commuter rail and rapid transit system serving the city centre of Paris and its suburbs. It acts as a combined city centre underground rail system and suburbs-to-city-centre commuter rail, similar to the S-Bahn in Germany, Austria and Switzerland, S-train in Copenhagen, the Pendeltåg in Sweden, the Overground and Elizabeth Line in London, S Lines in Milan, plus many other commuter rail networks around the world.

Conceived of as a métropolitain express ('express metro') during the mid-1930s, the scheme was revived in the 1950s and construction began in the early 1960s. The RER was not fully conceptualised until the completion of the Schéma directeur d'aménagement et d'urbanisme (rough translation: 'master plan for urban development') in 1965. The RER network, which initially comprised two lines, was formally inaugurated on 8 December 1977 in a ceremony that was attended by President Valéry Giscard d'Estaing. A second phase of construction commenced at the end of the 1970s which saw additional lines constructed along with extensions to the original two. The RER is operated partly by RATP, the authority that operates most of the public transport in Paris, and partly by the SNCF, France's national rail operator.

The Île-de-France tramways (French: Tramways d'Île-de-France) is a network of modern tram lines in the Île-de-France region of France. Fifteen lines are currently operational (counting Lines T3a and T3b as separate lines), with extensions and additional lines in both construction and planning stages. Although the system mainly runs in the suburban regions of Paris, lines T3a and T3b run entirely within Paris city limits, serving as a high capacity ring line replacing the Petite Ceinture bus route. Lines T2 and T9, on another hand, start their routes within Paris's borders before heading out. While lines operate independently of each other and are generally not connected, some connections do exist: between lines T2 and T3a (at the Porte de Versailles station, since 2009), T3a and T3b (at the Porte de Vincennes station, since 2012), T1 and T5 (at the Marché de Saint-Denis station, since 2013), T1 and T8 (at the Saint-Denis train station, since 2014), T8 and T11 (at both Villetaneuse-Université and Épinay-sur-Seine stations, since 2017), T3a and T9 (at the Porte de Choisy station, since 2021) and T6 and T10 (at Hôpital Béclère, since 2023). However, the final design of the entire planned tram network is fairly integrated. (The prefix "T" in tram line numbers avoids confusion with the numbering of Paris Métro lines, a pattern followed in other public transport networks such as the new cable car route in Créteil, dubbed C1.)

Most lines (with the exceptions of lines T4, T9, T11, T12, T13, and T14) are operated by the Régie Autonome des Transports Parisiens (RATP), which also operates the Paris Métro and most bus services in the Paris immediate area. Furthermore, while most lines use conventional steel-wheel rolling stock, two lines (T5 and T6) use rubber-tyred trams. Lines T4, T11, T12, T13 and T14 are tram-trains, sharing tracks with main-line railways, and are operated as part of French national rail operator SNCF's Transilien regional rail network.

Paris Métro Line 16 is one of four new lines of Grand Paris Express, a major expansion project of the Paris Métro. Currently under construction, the line will connect the suburbs north and east of Paris in the Seine-Saint-Denis department, and is planned to open in two phases in mid-2027 and 2028. Line 16 will be fully automated (along with all Grand Paris Express lines) and fully underground.

The line is being built by Société du Grand Paris, a public agency set up by the French Government to deliver the Grand Paris Express project. The trains will be operated by Keolis, while the infrastructure is managed by RATP.

Île-de-France Mobilités (French: [il də fʁɑ̃s mɔbilite]; IDFM) is a governmental authority (EPA) that controls and coordinates the different public transport companies operating in Paris and the rest of Île-de-France. In this capacity, it issues operating contracts for the various services, owns the buses and rolling stock used on those services, and acts as the main financing body for transport projects in the region. It coordinates the operation of RATP Group, SNCF, and the nearly 90 Optile-affiliated bus companies.

The origins of the organization can be traced back to the Syndicat des Transports Parisiens (STP), which was created by the French Government in 1959 to coordinate the various operations in the Paris region. The STP also provided oversight for the construction of the Réseau Express Régional and established the unified Carte orange fare payment system. In 1991, the STP was empowered to cover the entire Île-de-France region.

The French civil service (French: Fonction publique française) is the set of civil servants (fonctionnaires) working the Government of France.

Not all employees of the state and public institutions or corporations are civil servants; however, the media often incorrectly equate "government employee" or "employee of a public corporation" with fonctionnaire. For instance, most employees of the RATP and SNCF (metropolitan and national rail transport authorities) are not civil servants. The Civil Service is also sometimes incorrectly referred to as the administration, but, properly speaking, the administration is the compound of public administrations and public administrative establishments, not their employees.
