Lake Constance Belt Railway
Lake Constance Belt Railway (German: Bodenseegürtelbahn) is the name used for several contiguous railway lines, either around the entire Upper Lake of Lake Constance (Bodensee) or only along its northern shore. It was coined around 1900, when the trinational railway ring around the lake (Konstanz–Radolfzell–Friedrichshafen–Lindau–Bregenz–Rorschach–Romanshorn–Konstanz) was completed, but today the term is only used for the line from Radolfzell to Lindau in southern Germany.
