Austria's rail network, operated primarily by Österreichische Bundesbahnen (ÖBB), spans the country's varied terrain from the Vienna Basin to the high Alps, offering passengers a range of journeys that pass through landscapes largely inaccessible by other means of transport.

The Semmering Railway

The Semmering Railway, which crosses the Semmering Pass in Lower Austria, holds the distinction of being the world's first mountain railway built with a steam locomotive. Completed in 1854, it was added to the UNESCO World Heritage List in 1998. The route connects Gloggnitz to Mürzzuschlag across a series of viaducts, tunnels, and curved embankments that were considered an engineering landmark of the 19th century.

The Arlberg Railway

Running between Innsbruck and Bregenz in western Austria, the Arlberg Railway traverses the central Alps through the Arlberg Pass. The line passes through the Vorarlberg and Tyrol regions, offering views of glaciated peaks and river valleys. The route includes the Arlberg Tunnel, one of Austria's longest rail tunnels.

The Mariazellerbahn

The Mariazellerbahn is a narrow-gauge railway connecting St. Pölten in Lower Austria with the pilgrimage town of Mariazell in Styria. The line climbs significantly in elevation over its course, passing through forested highlands and crossing the Österreichische Voralpen mountain range. The route is operated by NÖVOG and is considered one of the most technically complex narrow-gauge lines in Central Europe.

The Brenner Railway

Connecting Innsbruck in Austria with Brenner on the Italian border, this historic corridor follows the Brenner Pass, the lowest of the main Alpine passes. The route has served as a major transit artery between Central Europe and the Mediterranean for centuries and continues to carry both passenger and freight traffic.

Glacier Express Connections

Austria also forms part of broader cross-border scenic rail corridors. The western regions connect with Swiss rail services, allowing passengers to continue onto internationally recognized mountain rail routes through coordinated European ticketing arrangements.

Open Questions

Plans for a high-speed Brenner Base Tunnel between Austria and Italy remain under development, raising questions about how freight redistribution may affect the passenger experience on legacy scenic lines in the region.
