The Oberweissbacher Bergbahn, renamed the Thüringer Bergbahn in 2020, is a railway line in the Thuringian Slate Mountains, now operated by DB RegioNetz Verkehrs GmbH Oberwei?bacher Berg- und Schwarzatalbahn. Since 1922, it has connected the Obstfelderschmiede stop on the Schwarzatal Railway with the municipality of Cursdorf. To overcome the height difference of more than 300 meters between the Schwarzatal valley and the plateau, a funicular railway with a gauge of 1800 mm was built from Obstfelderschmiede to Lichtenhain. In the middle of the funicular the car "Lichtenhain" is crossing the "Cabrio car", loaded on the "Güterbühne", in the Abt system passing loop.
