The approximately 27.3 km long Semmering Basistunnel is one of the most important and complex infrastructure projects in the heart of Europe. This double-tube railway tunnel is located between Gloggnitz and Mürzzuschlag, linking the two federal states of Lower Austria and Styria. As part of the new southern railway, which is the central axis on the trans-European route from the Baltic Sea to the Adriatic Sea, it represents a sustainable investment in both Austrian and European rail infrastructure.
