Koralm Railway 24.06.2025

The Koralm Railway forms part of the Baltic-Adriatic Corridor, a major trans-European axis that links economic regions and transport routes across the continent.

This project is not only of supraregional significance – it is also set to revitalise the economy in the south-eastern region of Austria. Until now, the fastest rail connection between the provincial capitals of Graz and Klagenfurt took around three hours. With the Koralm Railway, designed for speeds of up to 250 km/h, this travel time will be reduced to approximately 45 minutes. Construction of the Koralm Railway began in 1998. The full route spans 130 kilometres and includes numerous bridges, underpasses and tunnels. Its centrepiece is the 33-kilometre Koralm Tunnel, featuring two single-track tubes and ranking among the longest railway tunnels in the world. Passenger services on the full line are scheduled to begin at the end of 2025. The stamp depicts a visualisation of the Koralm Tunnel with an ÖBB Railjet locomotive of the 1116 series.
