NOHAB, (Nydqvist & Holm AB), Swedish manufacturing company in the city of Trollhättan. The company was founded by Antenor Nydqvist, Johan Magnus Lidström and Carl Olof Holm in 1847 as Trollhättans Mekaniska Verkstad as a manufacturer of turbines for hydraulic power plants. In 1865 the company made its first steam locomotive and in 1912 the 1,000th locomotive steamed out of the factory. In 1916 the company was reconstituted as a limited company and became NOHAB. In 1920 NOHAB received an order of 1000 locomotives from Russia. Only 500 where delivered between 1921 and 1924. In the 1950s NOHAB started manufacturing diesel locomotives under licence from Electro-Motive Division of General Motors. The Danish State Railways were a major customer. Also, 20 diesel engines were later built for Hungarian State Railways, but due to the Iron Curtain, the import was stopped. These locomtives were classified as type M61. Today, the M61s are no longer in use, but a preservation group exists in Hungary. In 1930 NOHAB started manufacturing the Bristol Jupiter aircraft engine, under licence from the Bristol Aeroplane Company. A couple of years later the aircraft engine division of NOHAB and AB Svenska järnvägsverkstäderna of Linköping formed the aircraft manufacturer SAAB. NOHAB was still a major manufacturer of turbines for power plants and well known for medium size ship engines. NOHAB also manufactured the hulls for the S-tank. The company went bankrupt in 1979.
