Austria’s Koralm Railway Opens to All Traffic: Now One hundred and Thirty KM Line Reduces Travel Time Between Graz and Klagenfurt to Forty Minutes

Published on December 20, 2025

On December 14, Austria officially opened the 130 km Koralm Railway to all traffic, a momentous achievement in the country’s transport infrastructure. The new line, which connects Graz and Klagenfurt, reduces travel time between the two cities to just 41 minutes, revolutionizing regional rail travel and providing a faster, more efficient option for both passengers and freight. This milestone marks the completion of one of Europe’s most ambitious and long-running rail projects.

Construction and Development

The Koralm Railway, a €6.1 billion project, was developed in multiple phases over several decades, with construction beginning in 2002. The project includes significant upgrades, such as the quadrupling of the main rail line south of Graz and the construction of the 33 km Koralm Tunnel, which began in 2008. The project’s extensive scope also involved the construction of more than 100 bridges and 50 km of tunnels, enhancing both the safety and efficiency of the new route.

The railway is designed for speeds of up to 250 km/h and is fully electrified at the Austrian standard of 15kV AC. As one of the European Union’s key transport corridors, the Koralm Railway serves as an integral part of the Baltic-Adriatic corridor, linking ports in Poland to the north with those in Italy, Slovenia, and Croatia to the south. The line provides a critical link for both passenger travel and transit freight across central Europe.

Operational Features and Capacity

The Koralm Railway is equipped with 23 stations and stops, ensuring accessibility for various towns and regions along the route. The line’s electrification and high-speed capacity make it a vital part of Austria’s efforts to improve its rail infrastructure and reduce congestion in urban areas. Upon its opening, the Koralm Railway received an enthusiastic response from passengers, with 10,000 people traveling on the line within the first few hours of its public launch.

In addition to its passenger services, the Koralm Railway has been fully operational for freight traffic since last month, significantly improving the efficiency of freight transportation across the region. The combination of high-speed passenger service and robust freight capacity will help facilitate better movement of goods and people, contributing to Austria’s position as a central hub for European transportation.

A Historic Milestone for Austria

“The full opening of the Koralm Railway is a historic milestone,” said Andreas Matthä, CEO of Austrian Federal Railways (ÖBB). “We are experiencing enormous interest in the new line, which will help shape the future of rail travel in Austria.” The Koralm Railway is expected to have a significant impact on regional development, improving connectivity between major cities, reducing travel times, and providing an environmentally friendly alternative to road transport.

The opening of the line marks the completion of one of Europe’s longest-running rail projects, a testament to Austria’s long-term commitment to modernizing its rail network. With the Koralm Railway now fully operational, ÖBB has set a new standard for rail services in Europe, ensuring that Austria continues to lead the way in sustainable and efficient transportation.

Economic and Environmental Impact

Beyond the immediate improvements to passenger and freight services, the Koralm Railway is expected to have a far-reaching economic impact. By reducing travel times and improving transport efficiency, the railway will help foster business growth, increase tourism, and enhance the region’s competitiveness. Additionally, the line’s environmental benefits are significant, as it provides a more sustainable alternative to road transport, aligning with Austria’s goals for reducing carbon emissions and supporting green transportation initiatives.

Conclusion

The Koralm Railway’s full opening marks a new chapter in Austria’s rail history, providing a fast, efficient, and environmentally friendly transport option between Graz and Klagenfurt. This new line will not only improve passenger services but will also facilitate greater freight movement across Europe. As one of the key links in the Baltic-Adriatic corridor, the Koralm Railway plays a vital role in connecting central Europe and positioning Austria as a key player in the region’s transport infrastructure. The completion of this €6.1 billion project stands as a testament to Austria’s commitment to modernizing its transport system and supporting economic and environmental sustainability across Europe.
