Thunes Mekaniske Værksted A/S, Thune for short, was a Norwegian manufacturing company that among other things built locomotives. The production facilities were last located at Skøyen. It traced its roots to a workshop founded by Anders Paulsen Thune in 1815 in Drammen. Anders Paulsen Thune was a blacksmith by profession. His son took over the enterprise, and in 1851 they moved to Christiania. By 1870 the production facilities were located in the street Ruseløkkveien. In 1871 Andreas Lauritz Thune, grandson of the founder, took over. The facilities were almost immediately moved to the nearby street Munkedamsveien. He started production of agricultural machinery and steam engines. Locomotive production began in the 1890s. Eventually, the locale in Munkedamsveien became too small for large-scale industrial production. Located in the centre of the city, it was difficult to expand. Instead, Thune bought the property Kjellebekk at Skøyen in Aker, a more rural municipality that surrounded Kristiania. In addition, Skøyen was served by a railway station. Thune moved to Skøyen in 1901, and all activity in Munkedamsveien was ceased by 1903. After moving to Skøyen, production of turbines was started.
