Île-de-France tramway Lines 3a and 3b
Île-de-France tramway Lines 3a and 3b (French: "Lignes 3a et 3b du tramway d'Île-de-France") are the first modern tramway in Paris proper since the 1937 closure of the previous comparable system. They are operated by the RATP ("Régie autonome des transports parisiens") and divided into two sections called T3a and T3b. The line is also known as the "Tramway des Maréchaux" because it follows the Boulevards of the Marshals, a series of boulevards that encircle Paris along the route of the former Thiers Wall (built from 1841 to 1844). The boulevards are, with three exceptions, named for Napoleon's First Empire marshals ("maréchaux"); they were transformed by redevelopment works carried out during the two and a half year construction of the line, which opened on 16 December 2006 under the designation T3.

The line initially ran in its own section of these boulevards' roadway between the 15th and 13th arrondissements, allowing it to connect the Pont du Garigliano and Porte d'Ivry in an average of 26 minutes. It carried 25 million passengers in its first year of operation, averaging 100,000 on weekdays and 70,000 on weekends; numbers have steadily increased ever since. In 2009, further work began to extend the line to the northeast, with the extension fully opening on 15 December 2012. Two separate lines were constructed to ensure the service's reliability: the existing line was extended to Porte de Vincennes and renamed T3a; a second line (T3b) initially connected Porte de Vincennes to Porte de la Chapelle. An extension of the latter to Porte d'Asnières near the border with Levallois-Perret opened on 24 November 2018.
