Opened in 1848, the vertex tunnel of the Semmering railway was the world’s first alpine tunnel. The ‘New Austrian Tunnelling Method’, which uses the geographical stress of surrounding rock to strengthen a tunnel, was developed from 1957 to 1965 and has since done a great deal to revolutionize tunnel construction around the world.
