Immendingen

Immendingen station is a junction station in Immendingen in the German state of Baden-Württemberg. The Black Forest Railway from Offenburg to Konstanz connects with the Danube Valley Railway from Donaueschingen to Ulm meet at the station. Immendingen is also served by trains on the Wutach Valley Railway, which branches at the neighbouring Hintschingen station via Blumberg to Waldshut; regular passenger services have been restored on the section of the line to Blumberg since 2004 as part of the Ringzug concept. Until the construction of the Tuttlingen-Hattingen (Baden) connecting curve in 1934, Immendingen was also the terminus of trains from Stuttgart running over the Plochingen–Immendingen railway and Stuttgart–Horb railway (Gäubahn).

The Danube Sinkhole (German: Donauversinkung or Donauversickerung) is an incipient underground stream capture in the Upper Danube Nature Park. Between Immendingen and Möhringen and also near Fridingen (Tuttlingen), the water of the Danube sinks into the riverbed in various places. The main sinkhole is next to a field named Brühl between Immendingen and Möhringen. The term "sinking" is more accurate than "seeping", because, instead of just distributing into the soil, the Danube's water flows through caverns to the Aachtopf, where it emerges as the river Radolfzeller Aach, a tributary of the Rhine.
