Line 6 is one of the sixteen lines of the Paris Métro rapid transit system. Following a semi-circular route around the southern half of the city above boulevards formed by ancient city walls (boulevards extérieurs), it runs from Charles de Gaulle – Étoile in the west and Nation in the east.
Opened between 1900 and 1906 from Étoile to Place d'Italie, the line at first carried the name 2 sud or circulaire sud ("southern circulator"), before being integrated for a long time with Line 5, while the section heading east to Nation opened in 1909. At that time, Line 6 took its current form.
13.6 km (8.5 mi) in length, of which 6.1 km (3.8 mi) are above ground, and equipped with rubber-tyred rolling stock since 1974, it is one of the most pleasant lines on the Métro. This is due in part due to is numerous views, sometimes exceptional, of many of Paris' most famous landmarks and monuments. With slightly more than 100 million riders in 2004, it is the sixth busiest line of the network.

Initially, the planners of the Métro envisaged a loop line such as the Circle line of the London Underground. However, the difficulties of operating such a line forced a separation of the circle into two lines: the north and south circulators. An initial plan was to run trains from Gare d'Austerlitz to Gare de Lyon, and from there operate along Line 1 to Nation. The abandonment of the project allowed designers to choose a new route via Place d'Italie to Nation; this option, using Bercy, is the origin of what is now Line 6.
The northern circulator, now Line 2, opened in 1903, while the tracks from Étoile to Trocadéro (referred to as Line 2 Sud) opened on 2 October 1900 as part of a branch of Line 1 meant to serve the World Expo of that year. The line was extended southward to Passy three years later but was not fully opened and only allowed four-car trains.
Work on the line was not particularly difficult, apart from the occasional sewer displacements and land stabilisation around Denfert-Rochereau due to old mines. On the other hand, the crossing of the Seine at Passy was much trickier; from 1903 to 1906, the construction of a viaduct over the Pont de Bir-Hakeim gave way to another project unrelated to the Métro. The original bridge, built in 1878, was replaced with one made of metal supporting the railway viaduct above. To the east, another bridge had to be built above the Pont de Bercy. Originally finished in 1864, it was enlarged by 5.5 m (18 ft) in order to hold the Métro and is the only viaduct in the system made of stone. Both the overpasses and underground stations in this section were designed similarly to those of Line 2 Nord, although elevated stations on the southern half are fully covered with side-walls made of brick, not glass.
On 24 April 1906, the line from Étoile to Place d'Italie opened.[1] In October of the next year, it was decided to merge the circulaire sud with Line 5, as a result running trains between Étoile and Gare du Nord via Austerlitz. This consolidation eliminated the 2 Sud designation.
Following the bombardment of Paris during World War I, elevated rapid transit lines became a defence system. Trains were no longer lit at night from February to July 1918. However, underground trains became incredibly dark and resulted in complaints from passengers and employees. La compagnie du chemin de fer métropolitain de Paris (CMP), which operated Line 5, was authorised to make electrical and lighting changes.
At the time, Line 6 was confined to the railway between Place d'Italie and Nation. Infrastructure works were completed in 1906, but the CMP was in no hurry to open what was perceived as a low-profiting stretch of track. Upon the urging of the City of Paris, the CMP opened Line 6 on 1 March 1909 and remained this way until 1931, when the need for a link across the southern part of the city was needed to provide access to a cultural exhibition at the Bois de Vincennes. Engineers decided upon Line 6 taking over the section west of Place d'Italie so as to create a line from Étoile to Nation, with Line 5 ending at Place d'Italie. After the exhibit closed, the old service pattern returned.
On 6 October 1942, at the height of the German occupation of the city, Line 6 was continually operated. The northern extension of Line 5 to Pantin significantly elongated the line; it was agreed upon that the line was too long, and the remedy was to end Line 5 at Place d'Italie, thereby creating a full southern loop from Étoile to Nation as Line 6 stands today.
A change in Line 6's operation occurred during the 1970s: Kléber station was expanded to four tracks with two island platforms, a rare arrangement in the Paris Métro, and converted to the line's control terminal, with Étoile acting as a simple turn-around stop.
After doing the same to Lines 1, 4, and 11, the RATP decided in 1971 to convert Line 6 to rubber-tyres for the sake of noise and vibration reduction not only to passengers but also residents near the elevated portions of the line. Work began the next year and finished in May 1974. During this time, a temporary yard was created with 810 m (2,660 ft) of track to facilitate vehicle movement. Simultaneously, the line was equipped with a central control station.
The MP 73 rolling stock quickly replaced the old Sprague-Thomson over the month of July 1974. Unlike the MP 59, which also has rubber tyres, the MP 73 has striped ones for better adhesion on long stretches of elevated track; the rails are ribbed for the same reason. No adhesion failure has been reported since the switchover, even in heavy rain.
Four stations on Line 6 have unique, cultural theming:
