Karawanken Tunnel

A new overhead line system is being built on the section between Rosenbach station and Jesenice station (SI). Part of this section is the Karawanken tunnel, which is located on both Austrian and Slovenian territory. An overhead conductor rail system and a radio system in accordance with the ÖBB regulations were installed in the tunnel. The following section of the line in Slovenia was completed according to their country-specific overhead contact line systems.

Using a drilling device specially designed by EUROPTEN, a total of 2,848 anchors for tunnel support points were drilled and relocated. Over the 8 km length of the tunnel, the elements of the overhead conductor rail were installed, the contact wire was pulled in and adjustment work was carried out on the overhead conductor rail system. A tunnel radio system was also built.
