The Austrian Southern Railway (German: Österreichische Südbahn) is a 577.2-kilometre (358.7 mi) long double track railway, which linked the capital Vienna with Trieste, the former main seaport of Austria-Hungary, by railway for the first time. It now forms the Southern Railway in Austria and the Spielfeld-Straß–Trieste railway in Slovenia and Italy.
