Today, traffic through the Arlberg railway tunnel has increased considerably, despite competition from road transport through the Arlberg Road Tunnel. This has made it necessary to widen the approach ramps for double tracks. Many long-distance, high-speed EuroCity and Railjet trains ply the route from Vienna to Vorarlberg over the Arlberg. On the occasion of the World Ski Championships in 2001, the railway station of St. Anton on the eastern side of the Arlberg Tunnel was relocated from the town centre to a new site on the north side of the valley. This required the Arlberg tunnel be lengthened and the construction of the new Wolfsgruben tunnel.
