Prior to the shortening of the main Bergen Line railway with the Ulriken Tunnel, the Bergen–Nesttun Line was an important commuter rail service, feeding suburban residents from Fana into the city center. In 1917, the section was the most heavily trafficked railway in the country, with a travel time between 20 and 27 minutes. There were up to 27 trains per day, of which five continued to Garnes. In 1918, the line was proposed for doubling and electrification: the latter was completed in 1954. The same year, annual ridership were down to 870,000 passengers. After the opening of the Ulriken Tunnel commuter trains were kept for six months, with the last trip ran on 31 January 1965.
