The Ulm–Friedrichshafen railway, also known as the Württembergische Südbahn, is a non-electrified main line in the state of Baden-Württemberg, southern Germany. It was built from 1846 to 1850 and doubled from 1905 to 1913. During that time many of the station buildings were rebuilt. Its kilometre numbering begins as the Fils Valley Railway in Stuttgart Hbf.
The Southern Railway begins in Ulm and runs via Biberach an der Riß, Aulendorf and Ravensburg to Friedrichshafen. Several trains continue on the single-tracked line of the Lake Constance Belt Railway to Lindau.
