The Baselland-Transport (BLT) Stadler Tango tram seen at Basel SBB

Basel has an interesting tram network where many lines lead beyond the city borders. Multiple lines end directly at the German border, one even crosses it and a line crosses over to France only to return to Switzerland for its terminus. To make it more interesting there are two tram companies, which is not unheard of, but very rare in Europe. The Basler Verkehrs-Betriebe operates the lines and infrastructure inside the city and Baselland Transport owns the tracks outside. They yellow BLT trams do come to the city centre though using the same tracks, and to make up for that, BVB is running the services on one of the interurban lines. Curious, isn't it? Since for the Hungarian page I simply translated the Wikipedia article and framed it into the document I will point you to the original English language article where you can find a lot of details about it.
