The Holmestrand–Hvittingfoss Line or HVB is an abandoned railway between Holmestrand to Hvittingfoss in Norway. It consisted of two sections: a 13.4-kilometer (8.3 mi) line from Holmestrand to Hillestad and a 10.4-kilometer (6.5 mi) section from Hof to Hvittingfoss. The two parts were connected by a 6 kilometers (4 mi) section of the Tønsberg–Eidsfoss Line. At Holmestrand Station, the line connected to the Vestfold Line of the Norwegian State Railways. HVB was opened on 30 September 1902 and closed on 1 June 1938. The main purpose of the line was the transport of wood pulp at Hvittingfoss, although it was also used for passenger transport until 1931.

The Tønsberg–Eidsfoss Line or TEB is an abandoned railway between Eidsfoss and Tønsberg in Vestfold county, Norway. In use from 21 October 1901 to 31 May 1938, the private railway connected the area of Hof to Tønsberg, the coast and the Vestfold Line of the Norwegian State Railways. The main purpose of the 48.10-kilometre (29.89 mi) narrow gauge railway was to connect Eidsfos Verk to the mainline, although the railway also operated passenger trains. The line shares 6 kilometres (3.7 mi) with the Holmestrand–Vittingfoss Line (HVB), the two which from 1934 were operated by the same company, Vestfold Privatbaner.
