Timeline of railway electrification in Norway: The Norwegian railway network consists of 2552 km of electrified railway lines, constituting 62% of the Norwegian National Rail Administration's 4114 km of line.  The first three mainline systems to be electrified were private ore-hauling lines.  The Thamshavn Line opened in 1909, and remained in revenue use until 1973, after which it was converted to a heritage railway.  It is the world's oldest remaining alternating-current railway and the only narrow gauge railway in the country to have been electrified.  It was followed by Norsk Transport's Rjukan and Tinnoset Lines two years later, and Sydvaranger's Kirkenes–Bjørnevatn Line in 1922.  The Norwegian State Railways' (NSB) first electrification was parts of the Drammen Line in 1922 and the ore-hauling Ofoten Line in 1923, which connects to the Iron Ore Line in Sweden.  The use of El 1 locomotives on the Drammen Line proved a large cost-saver over steam locomotives, and NSB started electrifying other lines around Oslo; from 1927 to 1930, the remainder of the Drammen Line, and the continuation along the Randsfjorden and Sørlandet Lines to Kongsvinger were converted, along with the first section of the Trunk Line.  In 1935, the Hardanger Line became the first section of new NSB track to be electrified.
