The two sections of the Parsenn funicular from Davos village to the Weissfluhjoch were inaugurated in the early 1930s. Extensive modernization of the first section to Höhenweg was carried out in 2002. The second section was upgraded in 2010.

The new funicular has two tracks and incorporates a large number of curves. One third of the line passes through a snow shed and over bridges. The snow shed was built to facilitate snow clearing. The track infrastructure has been upgraded, the superstructure replaced and the gauge widened from 80 cm to 100 cm. The track alignment was retained. Each of the two cabins can carry 110 passengers. Travel speed has been increased from 6.2 m/s to 9 m/s.

The funicular also serves five mountain restaurants as well as the Institute for Snow and Avalanche Research. Freight handling between the first and second sections has been speeded up significantly thanks to the new intermediate station. In the past, cargo had to be transferred through two rooms from one freight carrier on the first section to another on the second section using three cranes. The transfer can now be handled with a single crane.
