The Nederlandse Spoorwegen (NS) Class 1200 was a locomotive that was in service from 1951 until 1998. It was designed by Baldwin and built by Werkspoor Utrecht from 1951 until 1953. The electrical part was built by Heemaf Hengelo after a design of Westinghouse. Some parts (the bogies, and the electrical installation) were made in the United States as part of the Marshall Plan.

Originally 75 locomotives were ordered, but the order was reduced to 25 locomotives, instead more locomotives of the French Class 1100 were ordered.

After more than 40 years of service the Class 1200 was retired from service in 1998. While the 1201, 1202 and 1211 were preserved for musea, the 1214, 1215, 1218, 1221 and 1225 were bought by the Dutch freight operator ACTS in 1999 and were renumbered to 1251-1255, of which 4 are still in service.
