Introduction

With a total length of 130km the new Koralm rail-way links Graz with Klagenfurt. It was an impor-tant part of the Baltic-Adriatic Corridor which connects the Baltic Sea with the Adriatic. The Koralm railway is one of the major transport infrastructure projects – not only in Austria but in the whole of Europe. Due to the new high-speed railway the travel time between Graz and Klagenfurt was reduced from 3 hrs to approximately 1hr.
