The Thamshavn Line was Norway's first electric railway, running from 1908 to 1974 in what is now Trøndelag county. Today it is operated as a heritage railway and is the world's oldest railway running on its original alternating current electrification scheme, using 6.6 kV 25 Hz AC. It was built to transport pyrites from the mines at Løkken Verk to the port at Thamshavn, as well as passengers. There were six stations: Thamshavn, Orkanger, Bårdshaug, Fannrem, Solbusøy and Svorkmo. The tracks were extended to Løkken Verk in 1910.
