 The station was opened in 1879 as a halt on the Smaalens Line , now known as the western branch of the Østfold Line . The station building was designed by the Norwegian architect Peter Andreas Blix in the same Swiss cottage style as the stations Ås and Såner . In the 1950s , the station was frequently used by weekend guests from Oslo that visited the nearby conurbation Hvitsten for having a bath . A few years after the section of the Østfold Line between Ski and Moss Station was upgraded to double tracks , Vestby Station received a major renovation . A regulation plan for the station area was published in May 2010 , which involved increasing the number of car parking places .
