The NS (Nederlandse Spoorwegen) Class 1200 were a class of electric locomotives that were in service from 1951 until 1998. They were designed by Baldwin and built by a company called Werkspoor (based in Utrecht) between 1951 and 1953. The electrical parts were built by Heemaf (Hengelo) to a design by Westinghouse. Some parts like the bogies, and the electrical installation were made in the United States as part of the Marshall Plan. 75 locomotives were originally ordered, but the order was reduced to 25 locomotives. Instead more locomotives of the French Class 1100 locomotives were bought. In 1999 and following years, some locomotives of this class were bought by various Dutch train operators (ACTS and EETC) and are still in use.
