The first line in the present network was opened in 2010 to link the city center with the neighboring comune of Scandicci; the second line opened on 11 February 2019, linking the city center with Florence Airport.

The current network operator is GEST (Gestione Servizio tramviario), a subsidiary of the French RATP.

During the first 10 months of service, the total passenger served were 7 million, a result considered a success.

[12] On 16 July 2018, the line was extended from Florence Santa Maria Novella railway station to the current northern terminus, Careggi.

[14] The rolling stock of Line 1 consists of 19 AnsaldoBreda Sirio, already in use in other cities in Italy and around the world.

From here, the line should run through the city center in two different branches, also serving the Duomo in the initial planning.

[16] However, after the recent revisions, the line will probably not pass in Duomo[9] and will run partly underground (4 stops).

[17] As of 2022, the route has been finalised for completion at the end of 2023, with new stops at Lavagnini, Poliziano, Parterre, Libertà, Cavour and Piazza San Marco.

[18] Line 2 will be 7.5 km (4.7 mi) long[3] and will be fundamental in serving the city center, which is planned to become mainly pedestrian.

The line will have a terminus at Santa Maria Novella railway station and will serve the western part of the city.
