Ulriken Tunnel (Norwegian: Ulrikstunnelen) is a railway tunnel on the Bergen Line between Bergen Station and Arna Station in Norway. The 7,670-meter (25,160 ft) long tunnel runs under the northern part of the mountain Ulriken in Bergen. Before the tunnel was opened in 1964, the Bergen Line ran via Nesttun. This stretch is now a heritage railway, the Old Voss Line. The tunnel has single track and is electrified. The Norwegian National Rail Administration has plans for building a second track through the mountain.
