The Rjukan Line (Norwegian: Rjukanbanen), at first called the Vestfjorddal Line, was a 16-kilometre (10 mi) Norwegian railway line running through Vestfjorddalen between Mæl and Rjukan in Telemark. The railway's main purpose was to transport chemicals from Norsk Hydro's plant at Rjukan to the port at Skien, in addition to passenger transport. At Mæl the wagons were shipped 30 kilometres (19 mi) on the Tinnsjø railway ferry to Tinnoset where they connected to the Tinnos Line. The Rjukan Line and the ferries were operated by Norsk Transport, a subsidiary of Norsk Hydro. Construction of the line started in 1907, and it opened two years later. It became the second Norwegian railway to be electrified in 1911. It experienced heavy growth, and had fifteen electric locomotives in use. During World War II it was the scene of the Norwegian heavy water sabotage. After the 1960s production declined, and the railway was closed in 1991. It was kept as a heritage railway.
