term perspective for the rolling stock division was not bright, because it only delivered to the Dutch market. In 1972 the division was closed. Machinery Next to producing rolling stock, Werkspoor also remained active in machinery, and in particular ship engines. In its first years she built the machines for the protected cruisers HNLMS Koningin Wilhelmina der Nederlanden, HNLMS Holland (1896) and HNLMS Utrecht (1898). In 1910 it produced the first diesel engine for a sea-going ship, the Vulcanus, for the Bataafse Petroleum Maatschappij. In the early 20th century it also started to produce cooling machines in license from Linde AG. In 1960 a new big factory hall was built on the Amsterdam–Rhine Canal in Utrecht. It was to be used for the construction of large boilers and machines, the Apparatenhal, since 2013 known as Werkspoorkathedraal. In 1989 the engine division Stork-Werkspoor-Diesel (SWD) was bought by the Finnish company Wärtsilä. Aircraft Werkspoor was somewhat active in Dutch aeronautical industry. In 1925 it was involved in the construction of the first Dutch helicopter by Albert Gillis von Baumhauer. In 1930 KLM executive Albert Plesman ordered Werkspoor to create a cargoplane after a design by Joop Carley. The development of the Werkspoor Jumbo in cooperation with Pander & Son was plagued by the engine overheating. In 1931 the Jumbo made its first flight. The only specimen flew two years as a cargo plane for the KLM, and then seven years as a trainer. At the start of World War II the plane was lost in a bombardment. Werkspoor worked as a subcontractor for Fokker in the late 1930s. By February 1939 500 of the 2,000 employees working for Fokker were working at the Werkspoor location Zuilen. These were woodworkers, that had been moved because there was not enough room for them in the rapidly expanding Fokker factory in Amsterdam. The wings of the Fokker Fokker G.I, first flight 1937, were made of wood. The wings of the first G.I. were not built in Zuilen. Werkspoor did built wing parts for the Fokker G.I. In the 1950s the Netherlands, Belgium and the United States planned to build 460 Hawker Hunter fighter jets. In the context of a NATO plan part of this would be financed by America. The engines would be built by FN in Belgium. For constructing the airplane a consortium was founded. Fokker: principal contractor, also responsible for final assembly of
