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 from probably 1945-1956. 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.
