PLANUM and the Korlambahn
PLANUM has been supporting the Koralm Railway for more than two decades
ÖVG’s exclusive excursion in June 2025 gave us the rare opportunity to take a special trip on the Graz – St. Paul – Graz route and experience the Koralm Tunnel up close. The stop at the evacuation and rescue position in the middle of the Koralm Tunnel showed us the impressive safety precautions in place.
The management and employees are delighted – our locations in Graz and Klagenfurt will soon be just 50 minutes apart. The Koralm Railway, one of Austria’s largest infrastructure projects, will permanently change mobility in the south of the country.
PLANUM is proud to have made a significant contribution to the planning of this project of the century since 1998. Our team was able to contribute extensive expertise, particularly in the area of noise studies. We also carried out risk analyses for the temporary routing of Koralm railway traffic via the southern line (Feldkirchen-Werndorf section).
PLANUM also supported the route selection process – from the definition of the planning corridor to the optimal route variant between Werndorf and the provincial border – as well as the preparation of the environmental impact statements (EIS) for several sections.
The focal points of our planning work were:
Spatial development, transport and infrastructure
Noise and local spatial planning
Townscape, material and cultural assets
Leisure, recreation and tourism
PLANUM also took on public relations tasks to accompany the EIA process.
