 Construction of the line started in 1924 , with the line opening in 1940 . It allowed the district of Sogn access to Bergen and Oslo via the Bergen Line . Electric traction was taken into use in 1944 ; at first El 9 locomotives were used , and from 1982 El 11 . Until 1991 , the train connected with a ferry service from Flåm to Gudvangen . In 1992 , freight services were terminated , and due to low ticket prices and high operating costs , the line was nearly closed . In 1998 , Flåm Utvikling took over marketing and ticket sale for the line , prices were heavily increased and El 17 locomotives were introduced . The trains remain operated by the Norwegian State Railways ( NSB ) , while the line itself is owned and operated by the Norwegian National Rail Administration .
