The NS Class 600 were a class of 65 shunting locomotives built by English Electric in England between 1950–1957 for Nederlandse Spoorwegen (NS). The first 10 were built at Dick, Kerr & Co, Preston and the remaining 55 at Vulcan Foundry, Newton-le-Willows. They are very similar to the British Rail Class 11. Twenty-three locomotives were later fitted with radio remote-control, and renumbered in the range 671–693. In 2013 there are still two locomotives active daily in The Netherlands. One is active for Railpro in and the other is active for LOCON Benelux in Apeldoorn.
