Höllental Line Locomotive
Specialist for Steep Grades – Originally, the 10 class 85 heavy three-cylinder tank locomotives placed into service were built for the Höllentalbahn Line in the Black Forest, which was previously operated with costly and time-consuming cogwheel technology. The brawny class 85 units were able to master this difficult line exclusively with adhesion operation. There they turned out excellently until the conversion to electric motive power. Several of these athletic units then took on service on other German lines with steep grades such as Erkrath-Hochdahl until the end of their operation.
Prototype: German Federal Railroad (DB) class 85 as it looked "on the pedestal" in Freiburg. Version with Witte smoke deflectors.
