Oslo Central was built on the site of the older Oslo East Station ("", ), 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.
