The line in the region of Basel, Switzerland, is operated by Baselland Transport (BLT).
The Basel–Dornach railway line opened in 1902 when it terminated at Aeschenplatz [de] in Basel as part of the Birseckbahn (BEB).
It also has the almost-unique distinction of crossing an international border, as it passes through French territory for two miles and calls at the commune of Leymen in Alsace.
In 2017, the tram line 3 became the third international tram line in Basel when its terminus at Burgfelden Grenze was extended to Saint Louis station (Gare St. Louis) in France [1] Archived 2018-11-07 at the Wayback Machine.
On Wednesday 2 November 2011 at 23.35 on the way to Dornach the tram derailed and crashed into a house at Tramstrasse after the Münchenstein Dorf stop injuring six and causing damages of over CHF 100,000 Swiss francs[2]
