Arlbergbahn

The Arlbergbahn, or Arlberg Railway, is a standard gauge railway line in western Austria that connects Innsbruck in Tyrol with Bludenz in Vorarlberg, passing over the Arlberg Pass. It forms one of the principal Alpine north–south routes through the Eastern Alps and provides a key link between Tyrol and Vorarlberg.

Construction of the line began in the late 19th century as part of the expansion of the Austrian State Railways. It opened in 1884, with the Arlberg Tunnel as its centerpiece. At the time, the tunnel was among the longest in Europe and enabled reliable year-round operation across the high mountains, greatly shortening travel times.

The route climbs from Innsbruck through mountainous terrain and includes several tunnels and bridges, culminating in the long Arlberg Tunnel and descent toward Landeck and Bludenz. The line is standard gauge and, in the 20th century, was electrified and modernized to support growing passenger and freight traffic.

Today, the Arlbergbahn is operated by ÖBB and serves a mix of long-distance, regional, and freight trains. It remains an important cross-alpine conduit, linking Tyrol with Vorarlberg and providing access to ski resorts such as St. Anton am Arlberg and other Alpine destinations. The line also forms part of broader European rail corridors, contributing to tourism, regional mobility, and freight transport across the Alps.
