The railway was built between 1887 and 1890 primarily as a military 'strategic railway' to bypass neutral Swiss territory.
The line includes a 25-kilometer stretch with a total elevation change of 231 meters.
The loop geometry required to climb the valley side is so extreme that it resembles a pig's tail when viewed from above, hence the name.
The 'Blumberg Loop' is a rare example of a 'double-track' mountain railway alignment where tracks run parallel at different heights on the same slope.
The railway was decommissioned for regular transit in 1955 but was saved from dismantling by preservation efforts in the 1970s.
The route features a bridge over the Wutach River that stands 61 meters above the valley floor.
It is currently one of the few remaining railway lines in Germany to be designated as a technical monument.
The steam locomotives used are regularly maintained by a volunteer association dedicated to preserving the rolling stock.
The Sauschwänzlebahn is a heritage railway line running 25 kilometers between Blumberg-Zollhaus and Weizen in the southern Black Forest. The route is defined by its dramatic topography, featuring six tunnels, four bridges, and a tight loop that gives the line its name, which translates to 'pig-tail railway.' Originally constructed for strategic military purposes in the late 19th century, it was designed with a shallow gradient to accommodate heavy freight without needing rack-and-pinion assistance. The line traverses the Wutach valley and offers significant elevation changes while remaining within the limits of standard locomotive traction. It is operated as a museum railway using historic steam and diesel locomotives. Passengers pass through the Wutachschlucht region, a canyon area known for its geological complexity. The tracks form a distinctive spiral pattern to gain altitude, resulting in a journey that traverses the same hillside multiple times.
The viaducts near the spiral loop offer the most iconic views of the train against the valley landscape.
Book your seat in advance, especially during weekends, as historic trains have limited capacity.
Choose a seat in an open-air observation car for better photography, but bring a light jacket as the air cools significantly in the tunnels.
Combine your train ride with a hike along the Wutachschlucht trails to see the railway bridges from the forest floor.
Do not attempt to walk along the tracks outside of marked museum areas, as parts of the line remain active for maintenance vehicles.
Operates primarily from May to October, typically on weekends and selected weekdays. Closed during winter months.
Maintain caution around moving steam locomotives; remain behind safety barriers on platforms.
