The Pigtail Line
The Pigtail Line (Sauschwänzlebahn) takes you from Blumberg to Weizen,
passing 6 tunnels and 4 viaducts along this 25.5 kilometres route. It is
a section of the Wutach Valley Railway (Wutachtalbahn) in the southern
Black Forest, which connects the High Rhine Railway (Hochreinbahn) with
the Black Forest Railway (Schwarzwaldbahn).
The line was built in the late 19th century for military reasons, as
part of the so-called “strategic bypass railways” in the southern Black
Forest. The intention was to bypass neutral Swiss territory.
To remain below the maximum gradient of 10 per mil, the line had to be
artificially extended by adding a series of curves and tunnel
constructions. With its length of 1700 metres, the Grosse Stockhalde
spiral tunnel is the only spiral tunnel in Germany.
