Werkspoor N.V. was the shortened, and later the official name of the Nederlandsche Fabriek van Werktuigen en Spoorwegmaterieel. It was a Dutch machine factory, known for rolling stock, (ship) steam engines, and diesel engines. It was a successor of the company Van Vlissingen en Dudok van Heel, later named Koninklijke Fabriek van Stoom- en andere Werktuigen. In 1954 Werkspoor was merged with Stork.

Van Vlissingen en Dudok van Heel was a famous nineteenth-century Dutch machine factory. It built steam engines and machinery for the sugar industry and for maritime purposes, as well ships, rolling stock and large metal structures like the Moerdijk bridge and a floating dock. In 1871 it was reorganized to become the public company Koninklijke Fabriek van Stoom- en andere Werktuigen. In a second reorganization in 1890, parts of it were saved and continued under the name Koninklijke Nederlandsche Fabriek van Werktuigen en Spoorwegmaterieel, renamed to Werkspoor in 1927.
