The planned opening is in 2025,[1] along with the new double-tracked railway line from Nykirke to Barkåker.

[1] The Norwegian Railway Directorate has planned to have four trains per hour on the Vestfold line in the future.

[4] Two of these are to be express trains to and from Sandefjord and/or Tønsberg, and will bypass the stations in Horten, Holmestrand and Sande, from December 2025.

Horten Station is planned to only be serviced by trains with end stations in Tønsberg and Oslo, with no direct trains to Oslo Airport, Gardermoen or Sandefjord Airport, Torp.

The decision was based on statistics showing that 80 percent of travellers to and from Oslo on the Vestfold line use stations south of Horten.
