The existing Semmering Line goes over spectacular historical viaducts.

Existing Semmering Line

All-round service is making the "Semmeringbahn" between Lower Austria and Styria fit for the future. It is the oldest mountain railway in the world and essential for many commuters.

Past rock faces, through picturesque valleys and over historic viaducts: For almost 170 years, the Semmeringbahn has connected the Lower Austrian town of Gloggnitz and the Styrian town of Mürzzuschlag.

With around 180 trains per day, it is one of the busiest routes in Austria. To ensure you have a good journey as a passenger, ÖBB-Infrastruktur is refurbishing this mountain line and its railway stations.

Lifeline for the region

Both commuters and the regional economy are profiting from the modernisation. Because the Semmeringbahn is part of the Southern Line, which connects the provincial capitals of Klagenfurt and Graz with Vienna. From 2030, a new, modern high-speed section will head south through the Semmering Base Tunnel. That will take the strain of the heritage-listed mountain section, which is a UNESCO World Cultural Heritage site.
