Oslo Central Station (Norwegian: Oslo sentralstasjon, abbreviated Oslo S) is the main railway station in Oslo and the largest railway station on the entire Norwegian railway system. It is the terminus of Drammen Line, Gardermoen Line, GjøVik Line, Hoved Line and Østfold Line. It serves express, regional and local train services by four companies. The train station is owned and operated by Norwegian National Rail Administration and was opened in 1980.
Oslo Central was built on the site of the older Oslo East Station (Oslo Østbanestasjon, Oslo Ø), the combining of the former east and west stations being made possible by the opening of the Oslo Tunnel. Oslo Central has nineteen tracks, thirteen of which have connections through the Oslo Tunnel. The station has two buildings, the original Oslo East building and the newer main building for Oslo Central. Each building houses a large shopping centre. The square in front of the station is called Jernbanetorget.
