The Freiburg–Colmar railway was an international railway that formerly connected Freiburg im Breisgau, in the German state of Baden-Württemberg, with Colmar, in the French department of Haut-Rhin (région Alsace). The line crossed the river Rhine on a bridge between Breisach and Neuf-Brisach. Since that bridge was destroyed in 1945, the line from Freiburg has terminated at Breisach, and this stretch of line is now commonly called the Freiburg–Breisach railway, or the Breisacherbahn. The section from Freiburg to Breisach was completed in 1871 and the remainder in 1878.
