 Lysaker was one of two original Drammen Line station in Bærum , opening on 7 October 1872 . The original station building , designed by Georg Andreas Bull , burned down in 1914 and was replaced by a new station Adalbert Kielland . In the following years the elevated and double @-@ track layout was introduced . This station arrangement was demolished in 1987 to make way for a station designed by Arne Henriksen . Traditionally only served by commuter trains , the station was branded as Lysaker / Fornebu from 1990 to 2000 because of its vicinity to Oslo Airport , Fornebu . The station was rebuilt again from 2006 to 2009 in which it was expanded from two to four tracks . It became connected to the Asker Line in 2011 .
