The Strasbourg tramway (French: Tramway de Strasbourg, German: Straßenbahn Straßburg; Alsatian: D'Strossabàhn Strossburi(g)), run by the CTS, is a network of six tramlines, A, B, C, D, E and F that operate in the cities of Strasbourg in Alsace, France, and Kehl in Baden-Württemberg, Germany. It is one of the few tram networks to cross an international border, along with the trams of Basel and Geneva. The first tramline in Strasbourg, which was originally horse-drawn, opened in 1878. After 1894, when an electric-powered tram system was introduced, a widespread network of tramways was built, including several longer-distance lines on both sides of the Rhine.
