The SS ordered six tank engines for shunting work manufactured by
Beyer, Peacock & Company in
Manchester, England. They were delivered in 1877 and 1878 with numbers 261–266. Later, the locomotives were used more and more for passenger services. Originally the cab was open, but at the start of
World War I the cab was provided with lockable windows.
When the fleets of the HSM and the SS was merged into
Nederlandse Spoorwegen in 1921, the locomotives were given the NS numbers 5001–5006. The locomotives were withdrawn between 1927 and 1935. No engines have been preserved.[1]
