In addition to the termini at Vikersund and Krøderen there are intermediate stations at Snarum, Sysle, and Kløftefoss.
In the beginning of the 19th century, horse carriages and ships were used for passenger transport in the Buskerud area.
[1] In 1853, a committee was established, which aimed at improving the passenger transport between Drammen and the rest of Buskerud.
[2] Following the opening of the Randsfjord Line in 1866, railway director Carl Abraham Pihl instructed a terrain investigation of the area between Vikersund and Krøderen.
The terrain was difficult for railway construction; the right-of-way had sixteen sharp curves and the gradient from Vikersund was 1:45.
[8] In 1891, a pulp mill was established at Ramfoss, which became connected to the line with a side track from the newly created Kløftefoss Station.
[3] The timber origined from the forests around the line and was either floated to paper factories in Drammen or exported to England.
[5] At Gubberud and Slettemoen, side tracks from the line were laid down to transport timber from sawmills.
[12] In August 1910, a train derailed approximately 1 kilometre (0.62 mi) from Sysle Station because a creek had flooded and taken away all the ballast underneath the tracks.
The department supported the proposal, and in September 1977 the Norwegian Railway Club invited the heritage committee of Buskerud to an inspection.
