Semmering Base Tunnel: Railway Technology Contract Awarded
As part of the new southern route, the Semmering Base Tunnel provides a fast and safe connection between Lower Austria and Styria and strengthens the Baltic-Adriatic corridor in Europe. In June 2024 The Porr Group and Rhomberg Sersa Rail Group have been entrusted with the railway engineering equipment for the approximately 27-kilometre-long, twin-tube tunnel as part of the BTA Semmering Base Tunnel 4.1 consortium.

The 176 million euros contract includes telecommunications, electrical equipment with high-voltage systems, distribution boards, lighting and escape route labelling, as well as signage. The contract also includes the mechanical systems for air conditioning, ventilation and extinguishing water as well as locksmith work. The consortium partners have already started planning, and construction is set to begin in June 2025. The tunnel is scheduled to open 2030.
Following on from the Koralm Tunnel, this is the second major ÖBB tunnel project to be fitted out by the Porr Group and Rhomberg Sersa Rail Group (RSRG). Porr is once again responsible for commercial management, while RSRG is the technical lead.
