The system consists of two interurban lines, connecting central Lille to the nearby communities of Roubaix and Tourcoing, and has 36 stations.

[3][4] The first tram line in Lille was built 1874,[2] and the electrification of the town system started in 1894.

[2] While most urban lines in Lille were abandoned after 1950, the Mongy remained in service as the backbone of the public transport network of the TCC, the predecessor of Transpole.

[4][5] The lines originally terminated in the street outside the Opéra de Lille, but in 1994 were diverted into a tunnel and underground terminus at the Gare de Lille Flandres, offering interchange with both lines of the Metro.
