Paris Métro Line 7 in the context of "Paris Métro Line 7bis"

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.

Paris Métro Line 8 (French: Ligne 8 du métro de Paris) is one of the sixteen lines of the Paris Métro currently opened. It connects Balard (Porte de Sèvres) in the southwestern part of Paris to Pointe du Lac station in the southeastern suburban city of Créteil, prefecture of the Val-de-Marne department, following a parabolic route across Paris. Last line proposed by Fulgence Bienvenüe's original 1898 Paris Métro project, line 8 opened in July 1913 and was initially intended to link Porte d'Auteuil and Opéra. With 105.5 million passengers in 2017, it is the network's eighth busiest line, as well as the current third longest (after Lines 13 and 14, even though Line 13 has a fork, and Line 15 is set to become the longest once fully opened), at 23.4 km (14.5 mi) in length. Alongside Line 7, it serves 38 distinct stations, the most of any line on the network, Grand Paris Express (lines 15 to 18) included. Line 8 interchanges with all other Métro lines but three : Lines 2, 3bis and 7bis.

The line was substantially modified during the 1930s as Line 10 took over the western section from La Motte - Picquet to Porte d'Auteuil. The current route serves the southwestern part of the French Capital, including the Champ de Mars, the Invalides, the Concorde Place, the Opéra Garnier, the Grands Boulevards, The places of République and Bastille as well as the Bois de Vincennes, before ending in the southeastern inner suburbs through the communes of Charenton-le-Pont, Maisons-Alfort and Créteil, which the line reached in 1974 at Créteil–Préfecture station, after several extensions. Line 8 was the first to connect the prefecture of one of the new departments of Île-de-France, more than a decade before Line 5 to Bobigny, and Line 15 to Nanterre in the near-future. Line 8 is also the only Paris underground line to cross the Seine and its principal tributary, the Marne river, above ground via a bridge between Charenton – Écoles and École Vétérinaire de Maisons-Alfort, it also crosses the Seine underground between Concorde and Invalides.

The Parc de la Villette (French pronunciation: [paʁk də la vilɛt]) is the third-largest park in Paris, 55.5 hectares (137 acres) in area, located at the northeastern edge of the city in the 19th arrondissement. The park houses one of the largest concentrations of cultural venues in Paris, including the Cité des Sciences et de l'Industrie (City of Science and Industry, Europe's largest science museum), three major concert venues, and the prestigious Conservatoire de Paris.

Parc de la Villette is served by Paris Métro stations Corentin Cariou on Line 7 and Porte de Pantin on Line 5.

Opéra (French: [ɔpeʁa] ) is a station on Lines 3, 7 and 8 of the Paris Métro. It is named after the nearby Opéra Garnier. Located at the end of the Avenue de l'Opéra, it serves the district of Boulevard Haussmann. Its main entrances are located on the Place de l'Opéra, built in a marble design (instead of the characteristic iron metro entrances of Hector Guimard), to not spoil the view of the opera house.

The station is connected by an underground passage to Auber on RER A. From Auber, additional stations and lines can be reached via a sequence of underground passages, namely Havre–Caumartin for Line 3 and Line 9, and Haussmann–Saint-Lazare for RER E, the latter being connected to Saint-Lazare for Line 3, Line 12, Line 13 and Line 14, and the latter in turn being connected to Saint-Augustin for Line 9.

The MF 67 (French: Métro Fer appel d'offres de 1967; English: Steel-wheeled metro ordered in 1967) is a fleet of steel-wheel electric multiple unit trains for the Paris Métro. The first MF 67 trains entered service on Line 3 in June 1968, and became one of the biggest orders for the Métro, with 1,482 cars constructed. The need to replace the Sprague-Thomson fleet, as well as increasing costs associated with the later-cancelled plan to introduce rubber-tyred trains on all Métro lines, were the main factors for the size of the order.

At its peak, during the late-1980s and the early-1990s, the MF 67 operated on eight of the (then) fifteen Métro lines (Lines 2, 3 and 3bis, 5, 7bis, 9, 10 and 12): the MF 67 also operated on Lines 7, 8 and 13 (including the old Line 14), all before the introduction of the MF 77 in 1978.

La Courneuve–8 mai 1945 (French pronunciation: [la kuʁnœv ɥit mɛ milnœfsɑ̃kaʁɑ̃tsɛ̃k]) is a station of the Paris Métro and serves as the northern terminus of Paris Métro Line 7.

Mairie d'Ivry (French pronunciation: [mɛʁi divʁi]) is the southeastern terminus of Line 7 of the Paris Métro, in the suburban commune of Ivry-sur-Seine.

Louis Blanc (French pronunciation: [lwi blɑ̃]) is a Paris Métro station on line 7 and 7bis (serving as the western terminus of Paris Métro Line 7bis). The station is named after rue Louis Blanc, which honours Louis Blanc (1811–1882), who published political works, which led to the foundation of the French Socialist Party. He was a member of the Provisional Government of 1848 and had exiled himself to London during the Second Empire from 1848 to 1870. He was then elected to the French National Assembly in 1870.

The station has two island platforms and two side platforms, a layout rarely found elsewhere in the Métro.
