# Paris Métro Line 7

Paris Métro Line 7 is one of sixteen lines of the Paris Métro system. Crossing the capital from its north-eastern to south-eastern sections via a moderately curved path, it links La Courneuve–8 mai 1945 in the north with Mairie d'Ivry and Villejuif–Louis Aragon in the south, while passing through important parts of central Paris.
Line 7 began operating in 1910 and, along with Line 13, is one of only two Métro lines that splits into branches. Originally, this was in the northeast and splitting at Louis Blanc, which was separated in 1967 to become Line 7bis. In 1982, a new branch was added in the southeast to Mairie d'Ivry, branching off at Maison Blanche. Line 7 has only steel rails.
At 18.6 km (12 mi), Line 7 is one of the longest in the Paris Métro network. In addition, it contains the most stations as well as being the fourth most-used line of the Métro, with 135.1 million riders in 2017.

## History
### Chronology

* 5 November 1910: Line 7 was opened linking Opéra to Porte de la Villette.
* 18 January 1911: A new branch was opened from Louis Blanc to Pré-Saint-Gervais.
* 1 July 1916: The line was extended in the south from Opéra to Palais Royal.
* 16 April 1926: The line was extended from Palais Royal to Pont Marie.
* 15 February 1930: While a tunnel was being built on line 7 to cross the River Seine, a new section between Place Monge and Place d'Italie was opened and temporarily operated as part of Line 10.
* 3 June 1930: The line was extended from Pont Marie to Pont de Sully.
* 7 March 1930: That section temporarily operating as part of Line 10 was extended from Place d'Italie to Porte de Choisy.
* 26 April 1931: The section between Pont de Sully and Place Monge was opened. The section between Place Monge and Porte de Choisy was transferred to Line 7 and it was extended to Porte d'Ivry simultaneously.
* 1 May 1946: The line was extended from Porte d'Ivry to Mairie d'Ivry.
* 1967: Because of a lack of traffic, the northern branch of the line 7 between Louis Blanc and Pré-Saint-Gervais became a new independent line known as Line 7bis.
* 4 October 1979: The line was extended to the north from Porte de la Villette to Fort d'Aubervilliers.
* 10 December 1982: A new branch was opened to the south from Maison Blanche to Le Kremlin-Bicêtre.

* 6 May 1987: The line was extended from Fort d'Aubervilliers to La Courneuve – 8 mai 1945.

### Future

* An extension of Line 7 from La Courneuve–8 mai 1945 to Mairie de Drancy may be considered in the future.
* Line 7bis, the branch line of Line 7, may be merged with Line 3bis to form a new line, with its western terminus at Château-Landon on Line 7.

## Route and stations
### Route

Line 7 runs for 18.6 km (12 mi) completely underground, stopping at 38 stations. Southbound trains terminate alternately at Villejuif - Louis Aragon and Mairie d'Ivry, diverging at Maison Blanche. Late at night, through trains only operate to Mairie d'Ivry; a shuttle train to Villejuif originates at Maison Blanche.
In the north, the line begins at La Courneuve in the department of Seine-Saint-Denis at the intersection of National Routes 2 and 186. La Courneuve station acts as a transfer between the Métro and Paris' fragmented, suburban tramway system, with a station on Paris Tramway Line 1 (T1). Unlike most stations in Paris, there are three tracks, the central one used for departures and arrivals.
Running below National Route 2 (RN2), the line heads to the south-west, entering Paris in two single-line tunnels so as to avoid a now-unused terminal loop at Porte de la Villette. It then descends a 4% grade below Canal Saint-Denis and then climbs back up to stop at Corentin Cariou. Two stations beyond, Line 7 reaches Stalingrad, an important transfer point in the Métro system, where the line turns to run below Rue La Fayette.

## Rolling Stock

Line 7 currently uses 69 MF 77 trains, which run on the system’s longest lines. The trains were refurbished between 2019 and 2022 adding a reddish interior and a new livery which is also seen on the MP 14 and the future MF 19, MR3V/MR6V and MRV trains. The trains are to be replaced by the MF 19 trains in 2033-2035 and will be the last line to run trains equipped with DC motors and without open gangways.
