The Eastern Railway , formerly also known as the Vienna-Raab railway , is a two-track, electrified railway line that runs from Vienna towards Hungary. The name Eastern Railway refers to several branches of the line as well. At present the western terminus of the railway line in Vienna, Wien Südbahnhof, is being replaced by the new Hauptbahnhof. That will allow continuous east-west traffic and will connect the Eastern Railway directly to the Western Railway and Southern Railway.
