Eutingen im Gäu–Freudenstadt railway

The Eutingen im Gäu–Freudenstadt railway is a railway line in the German state of Baden-Württemberg that runs from the cultural landscape of the Gäu to the eastern edge of the Black Forest, connecting Eutingen and Freudenstadt. It is a section of the Gäu Railway from Stuttgart to Freudenstadt opened on 1 September 1879.

The line was the link from the state capital of Stuttgart to the Kinzig Valley Railway. Both the Gäu Railway and the Kinzig Valley Railway were main lines until 1974. Since the mid-1970s these railways were threatened time and again with closure. Not until 2006 was comprehensive electrification and renovation work carried out as part of the development of the Freudenstädter Stern regional network. Finally the line was integrated into the Karlsruhe Stadtbahn network and once again after a decade a direct link to Stuttgart was introduced.
