Badische Hauptbahn
On 1 August 1945, the operation of a limited third class suburban passenger service commenced, using freight trains. Of these, one ran from Norsingen (on the Rhine Valley Railway to the south) to the Hauptbahnhof and another two ran from Denzlingen (in the north) and Hugstetten (on the Breisach Railway) and terminated in the marshalling yard. The line from Himmelreich ("Höllentalbahn") ran to Wiehre station. It was not until 19 December 1950 that repairs were completed to the damaged tracks on the Höllentalbahn and the Loretto tunnel, which had been blown up by the retreating Wehrmacht, restoring two tracks between Wiehre and Freiburg Hauptbahnhof. As early as October, the Baden Mainline had been restored to two-track operations, as the result of Swiss diplomacy.
