The Wutach Valley Railway or German: Wutachtalbahn is one of the most unusual and impressive stretches of railway in Germany. It links the town of Waldshut-Tiengen, on the Upper Rhine Railway (Hochrheinbahn) and the border of Baden-Württemberg and Switzerland, with Immendingen on the Black Forest Railway (Schwarzwaldbahn). Because of the twisting route of its central section, it is popularly known as the Sauschwänzlebahn (pigtail line).

The line was planned in the 1860s, though construction was not completed until the 1890s, and its purpose was at least partly strategic, to allow a means for moving military supplies around the south of the Black Forest; the German Empire having seized Alsace and Lorraine from the French in the Franco-Prussian war of 1870-71, a revenge attack in this area from the French or a preemptive strike to prevent one were key issues in German military thinking at the time. The normal commercial route along the Rhine passed into Swiss territory so could not be used for military purposes.

The southern section of the line, following the valley of the Wutach river from Waldshut-Tiengen to Weizen (part of the town of Stühlingen), is relatively conventional. However, the middle section, from Weizen to Blumberg, involved an approximately 250 meter gain in height, and the military authorities specified that the line must not have a gradient of more than 1:100. Accordingly, the line proceeds in a series of curves (including one complete circle), taking 26.5 km of track to travel a beeline distance of 9.5 km, with spectacular large viaducts, tunnels and bridges including the only spiral railway tunnel in Germany. The track is of standard gauge and is mainly single track; the bridges and tunnels were built on a scale to allow eventual doubling of the track, though this was never carried out. The final section, from Blumberg to meet the Black Forest Railway near Geisingen, is again relatively conventional.

The line did indeed play a strategic role at various times in its history, and its most recent refurbishment (in the early 1960s) was carried out with NATO funds. However, in the period after the Second World War its commercial use declined, and, section by section, passenger service was withdrawn, though the southern section remained open for freight traffic until 2001. After the Deutsche Bundesbahn withdrew passenger services on the central section in 1974, a voluntary organization was set up in 1976 to re-open it as a museum line under steam traction, and it is now a popular tourist attraction. There have been a number of initiatives to re-open passenger services on the other sections of the line as part of a regional transport strategy, and since December 2004 the northern section has formed part of the 3rd Ring Railway (3er Ringzug) network of local railway lines in the south-eastern part of the Black Forest, in the districts of Tuttlingen, Rottweil and Schwarzwald-Baar. The southern section remains out of regular use, though the line remains usable.
