Paris Métro Line 9 is one of 16 lines of the Paris Métro. The line links Pont de Sèvres in Boulogne in the west with Montreuil in the east via the city center of Paris, creating a parabola type shape to its route. It is the third busiest line on the network. Line 9 interchanges with all of the 13 other main Métro lines, except for one, not including 3bis and 7bis according to the RATP maps. There is, however, a connection to Line 12 via the underground passageway from Saint-Augustin to Saint-Lazare.

Origins
Line 9 was originally envisioned as a branch of Line 2 Sud between Porte de Saint-Cloud and Trocadero. However, it was concluded by the CMP to combine this segment with a proposed segment that was to be built towards Opera, and thus Line 9 is created. The first section between Trocadero and Exelmans opened on 8 November 1922.
Construction and Extensions
Construction of the original sections proved to be difficult due to public opposition in the various arrondissements as well as unstable soil above the tunnels. Public support for the line's construction was greatly difficult due in part to proposed sections that various entities saw as impossible to build and operate under government regulations at the time. In addition, unstable soil led to the collapse of several sections of tunnel being constructed. The double-decker tunnel, which is located between stations Richelieu - Drouot and République was especially problematic due to unstable ground at Grand Boulevards. As a result, this particular section had to be reinforced by central piers. The first extension into the suburbs, towards Pont de Sèvres, opened on 3 February 1934. On 14 October 1937, the eastern extension towards Mairie de Montreuil opened. Since then, few changes to the line's infrastructure have been made.
Rolling stock
Line 9 is operated with the MF 01 stock in five-car sets. Before that, line 9 was the last line equipped of the pre-war Sprague-Thomson-trains, which were removed from service on 16 April 1983. On 9 February 2011, the STIF announced plans to acquire 66 new Mf 01-trainsets. The €330 million order began deliveries during June 2013 and will continue through 2016 to replace the current stock on line 9. The Last MF67 on Line 9 was pulled from service on November 28, 2016. On 21 October 2013, the first MF 01 railcar entered revenue service along Line 9, after spending the course of June through September running along Line 5. The Auteuil workshops, which Line 10 used to share with Line 9, was not equipped to handle maintenance operations for the MF 01 rolling stock, and thus heavy maintenance work was done at the Bobigny workshops along Line 5.
