Albtalbahn
With the help of the state of Baden-Württemberg, it founded the Albtal-Verkehrs-Gesellschaft (Alb Valley Transport Company, AVG) on 1 April 1957, which took over the Alb Valley Railway from the DEBG and immediately began renovating it. This work included the change of the electrification equipment to 750 volts DC. The first section from Albtalbahnhof to Rüppurr was opened on 18 April 1958. From then on the electric multiple units of the Alb Valley Railway continued from the Albtalbahnhof to the centre of Karlsruhe, so that most passengers did not have to change trains.
