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 Oberweißbacher 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. From Lichtenhain to Cursdorf there is a standard gauge line electrified with 600 V DC. Train 29934 of the line RB61 with electric railcars ET 479 # 205 and # 203 in multiple control is entering Cursdorf. # 205 was rebuilt as "Olitätenwagen" with glass roof and has no pantograph anymore, the power for the electromotors comes over a cable from # 203. Olität (plural: Olitäten) was the name given to a fragrant oil, a fragrant essence or ointment, and similar products.
The term refers to an oil distillate or a mixture of substances with an oily consistency. It originates from late medieval pharmacy and is derived from the Latin oleitas or oliditas.
