Sattel Pass, Rail mountain pass in Schwyz, Switzerland

Sattel Pass is a railway mountain pass in central Switzerland that connects Pfäffikon and Seewen at an elevation of 932 meters (3,058 feet). The tracks are specially engineered to navigate the steep mountain terrain while maintaining safe gradients for train operation.

The pass served as an important route since the 13th century and played a role in developing connections to the Gotthard Pass. When railways expanded in the region, the route was engineered to meet modern transportation demands through the mountains.

The name Sattel refers to the saddle-shaped terrain around the village of Sattel SZ, while the highest point of the crossing near Rothenthurm is called Biberegg. Since the Südostbahn line opened in 1891 from Goldau to Rapperswil, the pass has been one of the main west-east links between central and eastern Switzerland.

The pass road is the Hauptstrasse 8 section between Pfäffikon and Schwyz, running between the villages of Sattel and Rothenthurm, with the summit at 932 m and gradients reaching 7%. The Südostbahn railway from Goldau to Rapperswil, opened in 1891, crosses the pass and gives a car-free way over it. The highest point of the crossing, near Rothenthurm, is called Biberegg.
