The new southern railway section from Vienna to Klagenfurt via Graz, is one of the largest and most significant technical advances of the century in terms of infrastructure. ÖBB lnfrastruktur AG, commissioned by the Republic of Austria, is investing approximately 11 billion euros in the extension of the entire southern track in Austria. The 27.3-kilometre long Semmering Base Tunnel is one of the key projects of this investment, in addition to Vienna's Central Railway Station and the Koralm Railway.
