Austrian Southern Railway Company

The Südbahn-Gesellschaft (literally South Railway Company) was an Austrian corporation that built and operated numerous railway lines in the Austrian empire, Austria-Hungary (after 1867) and for some time in Austria, Hungary, and the Kingdom of Yugoslavia (after 1918).

The company was notable for two reasons: First, the split-up of its assets after the end of World War I took almost two decades. Second, the company existed even after ending all railway operations as an administration of assets, mainly for securing the pension claims of its former employees.
