Sperillen Line
The Sperillen Line () is an abandoned railway which ran through Ringerike in Viken county, Norway. The long line had five stations, starting at Hen Station on the Randsfjord Line and continuing to Lake Sperillen where it connected with a ferry at the port of Finstad. The rail line had additional stations and stops at Hallingby, Somma, and Ringmoen at the south end of Lake Sperillen. The steam ship DS "Bægna" had provided ferry and freight transport service from the southern end of Lake Sperillen to Sørum at Sør-Aurdal in Oppland at the northern end. "Bægna" went in  service from her maiden voyage on 13 October 1868 and continued in traffic until 1929, when it was replaced with a motor ship, DS "Spirillen". In 1921, Parliament voted to build a railway between the Randsfjord Line and a new port at Finsand on Lake Sperillen to connected for the ferry service. In 1933, passenger service on the rail line was terminated, as was the ferry traffic on Lake Spirillen. Freight trains on the rail line were terminated in 1957.
