NS Class 400

The Nederlandse Spoorwegen (NS) Class 400 was a derivative of the successful Class 200, also built for shunting duties. They were larger than their predecessors, and were built by Werkspoor in 1947. They were called "Grote Siks" (big goats). Unlike their predecessors, they were generally unsuccessful and in 10 years were replaced by the larger Series 500 and 600.
