The Nederlandse Spoorwegen (NS) Class 200 diesel locomotives were built for shunting duties.

The few locomotives in active service were retired in 2008 after new Dutch personnel safety regulations prevented NS from using them any longer.

As the handle could be moved by in-train forces while dead-heading it was required to be fixed by a nut and bolt.

In some cases, this was forgotten, and the result was that the operator couldn't brake; many Siks have suffered collision damage due to this.

Of all locomotives of the NS 200 series, many have been preserved in either a running condition at heritage railway lines, for spare parts, or as a static object.
