 Proposals for an upgrade of the Drammen Line to accommodate more trains started in 1991 . This resulted in the Asker Line , which was built in two steps between 2005 and 2011 . Ahead of the section stage , consisting of the Bærum Tunnel which would allow trains to run directly from Lysaker to Sandvika , Lysaker Station received a full modernization . The upgrades consisted of demolishing the existing station and building a new station with two island platforms . Snøhetta won the architecture competition for the station . The upgrades allowed several advantages : seven minutes shorter travel time west of Oslo combined with better regularity , trains previously turning at Skøyen Station could instead turn at Lysaker and a near doubling of the number of trains running through the West Corridor , allowing eleven more trains per hour .
