NS Class 600

The NS Class 600 was a class of 65 diesel shunting locomotives built by English Electric in England between 1950 and 1957 for the Dutch railway operator Nederlandse Spoorwegen. The first ten were built at Dick, Kerr and Company in Preston and the other 55 at the Vulcan Foundry in Newton-le-Willows, and the design is very similar to the British Rail Class 11. The class had a 400 hp 6KT diesel engine and a Knorr brake for train use, which set it apart from the similar Class 500 with its 350 hp 6K engine and an engine brake only. Twenty-three locomotives were later fitted with radio remote control and renumbered in the range 671 to 693. NS withdrew the class in the early 2000s, but many have been preserved, including several repatriated to England, and in 2013 two were still active daily in the Netherlands.
