Its green trams operate mostly in the city, although termini of its lines 3, 6, 8 and 14 are across the cantonal or country border.It owns the tram infrastructure in Basel-Land und runs the lines 10, 11 and 17 who are passing through Basel on BVB-tracks.In 1900, the Basel tramway network acquired an international dimension, when a new cross-border line was opened to Sankt-Ludwig (now Saint-Louis, Haut-Rhin), in the then German Empire.But that Birsigthalbahn (Birsig Valley Railway) would be joined to the general tram network of Basel as late as in 1984.Construction started in 2015 to extend Line 3 from its then-terminus at Bourgfelden Grenze to Saint-Louis station in France.[9] Late-night services on the cross-border line were suspended in 2019 due to a series of attacks in which laser pointers were used to obstruct the vision of tram operators.
