The Île-de-France contemporary tramway is made up of ten distinct lines, each with a different history and different materials. Seven have been created from scratch on urban roads, and three are the result of the modernization of formerly under-exploited railway lines.

In addition to the metro and the bus network , Paris and its region have owned a major tramway network that operated between 1855 and 1938 in Paris and until 1957 in Versailles . Faced with the chronic congestion caused by the automobile, a new public transportation policy was introduced in the 1970s , including the return of the tramway. A first line in Paris suburbs reborn in 1992 between Saint-Denis and Bobignyin the department of Seine-Saint-Denis . A second appears in 1997 , born from the reconversion of the Coteaux line in the Hauts-de-Seine . Two others were opened in 2006 , marking the return of the tramway in Paris, which will be extended and split in two in 2012 , and a tramway line (although exclusively covered by tram-train equipment) in Seine-Saint-Denis. Since then, several additional lines have been planned, announcing a strong development of this mode of transport during the 2010s . Two lines open in 2013 , one of which marks the arrival of the tramway on tiresin the Paris region. At the same time, due to the significant costs of creating new tram lines, the Île-de-France region favors the development of high-level service bus lines (BRTs).
