The locomotive was used from 1908 until the 1950ies. In 1972 it was moved to Trondheim and displayed near the Norwegian University of Science and Technology. Appears to be plinthed.
context_page_description: 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.
  It is Scandinavia's only railway with a rail gauge of 1,000 mm, though the nearby Trondheim Tramway also features this gauge. It is the world's only railway with this combination of gauge and electrical equipment. The total length of the railway was 25.15 kilometres. The transportation of passengers ended in 1963, but the transportation of ore continued until 1974. In 1983, parts of the railway were reopened as a heritage railway.
context_section_description: The first locomotive that was used on the line was Kvenna (the Coffee Grinder), a steam locomotive that had been bought from the Nesttun–Os Railway and converted from 750 mm (2 ft 5 ¹⁄₂ in) to the 1,000 mm (3 ft 3 ³⁄₈ in) metre gauge. In 1918 it was attempted to sell the locomotive to the Trondheim Tramway, the only other metre gauge railway in Scandinavia, but it is not known if the sale was successful. One more steam engine was bought from the German manufacturer Borsig. The line initially bought three electric locomotives from Elektrisk Bureau, who also delivered the transformers and overhead lines. The locomotives were based on a design from British Westinghouse. At the same time there was delivered a rail car named the King's car since the king had ridden in it during the opening of the line.
  The next order came in 1910 for two new rail cars and in 1916 for two new locomotives from ASEA at 420 kW, with an additional 12 pyrites cars in 1929-31 and 20 during the war. The company also bought a used Orenstein & Koppel steam engine from the zink mines in Odda in 1939 and during the war two Germany steam engines were transferred from Deutsche Reichsbahn.
  During and after the war there was used a lot of energy on rebuilding the locomotives that had been sabotaged. The three Westinghouse locomotives were rebuilt to two. In addition three new locomotives were delivered from Skabo in 1950. The last steam engine was retired in 1953. In 1952 two diesel shunting engines were delivered from Ruston & Hornsby.
  Three of the original passenger cars delivered to the opening in 1908 are still in use on the heritage railway. The last one, nr. 12, has been regauged and used on the heritage Setesdal Line since the 1970s. Some freightcars are still existing, including a dozen ore cars, but none are in serviceable condition.
