The station opened along with the Drammen Line on 7 October 1872. The original station building was designed by Georg Andreas Bull in Swiss chalet style. The station underwent a renewal from 1917 to 1922, receiving gauge conversion to standard gauge, electrification and a new station building designed by
Ragnvald Utne. Double track was laid from 1955 to 1958, including building the Asker Tunnel just northeast of the station, and a new station building opened in 1960. The Lieråsen Tunnel opened in 1973, cutting the distance to Drammen, and resulted in the old line becoming the Spikkestad Line. The station received an overhaul in 1998 and again in 2006. The latter was in conjunction with the construction of the Asker Line.
