the dismantling. The number of trains running between Freiburg and Offenburg was now much less substantial than directly after the opening of the line, 100 years earlier. Moreover, Germans could only use third class on the majority of the few trains running until 14 May 1950. In 1952, there were again 12 pairs of expresses on the Baden Mainline. 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. The state railway of the French occupation zone in 1945 decided to continue the operation of the 20 kV 50 Hz experiment on the Höllentalbahn, which had operated on the line between 1936 and 1944. Electrification on the Baden Mainline at 15 kV 16 2/3 Hz, started in 1952, was completed to Freiburg by the end of May 1955. As the locomotives could not operate at 50 Hz, steam locomotives hauled freight trains from the Freiburg freight yard via the Hauptbahnhof to the Höllentalbahn. This system ran for five years before the experiment on the Höllentalbahn was abandoned. The two-system operation also made the establishment of ab eighth platform track necessary. With the electrification of the main line from Basel, a class E 10 electric locomotives hauled the first service to Freiburg on 4 June 1955, a day later it was hauled by a class 38 steam locomotive to Stuttgart. Cleanup work on the station building did not begin until the autumn of 1947 and it was slow due to personnel shortages and poor materials until the currency reform of 1948. Freiburg station was rebuilt with a temporary entrance building, which was one of the first station buildings built in a German city after the war. The opening took place on 9 November 1949 in the presence of
