Arlbergbahn Mountain Railway between Landeck (Tyrol) and Bludenz (Vorarlberg), 63 km long, built under the supervision of Julius Lott in 1880-1884 in order to connect Tyrol with Vorarlberg and Switzerland. Runs under the Arlberg Pass in the 10.3 km Arlberg tunnel between St. Anton (Tyrol) and Langen (Vorarlberg), electrified in 1925. Outside of the Arlberg tunnel, the railway used to be only a single-track line that has been expanded to a double track in certain sections since the early 1990s (e.g. between Schnann and St. Jakob am Arlberg, completed in 1997). The maximum incline of the railway's eastern ramp is 26:1000, the western ramp's maximum is 31:1000. There are 31 tunnels and aqueducts as well as 26 large bridges and viaducts on the Arlbergbahn line; the most famous bridge is the impressive Trisanna Bridge.
