Trains on the Vestfold Line therefore terminated at Drammen, where passengers had to transfer to the Drammen Line. The low standard became a local political concern. The road director proposed closing the railway and building a highway, but the proposal met diminutive support. A propaganda committee was established in 1931, which in addition to gauge conversion insisted on that the line be rebuilt so it run via Horten. Parliament voted in favor on 26 June 1934 of converting the Vestfold Line. However, with the German occupation of Norway between 1940 and 1945, the Vestfold Line received a low priority and was hardly maintained. A new decision to convert the gauge was taken by Parliament in March 1946.
