Donautalbahn
Towards the end of World War II, Allied air strikes reached the cities and towns along the railway. In December 1944, Allied bomber squadrons completely destroyed Ulm Hauptbahnhof, as well as the nearby shunting yard at Söflingen. Heavy damage was also caused during the course of 1944 at the stations in Mengen and Tuttlingen. The railway itself escaped most harm, and was serviceable, with some limitations, throughout the war. Heavy damage to the line was then caused by the retreating Wehrmacht, which blew up several railway bridges, disabling through traffic on the Danube Valley Railway until 1950. Sections of the line were back in service as soon as 1946.
