The NS 8800 was a series of tank engines of the Dutch railway NS for the shunting service. Of the approximately 324 British-built Hunslet Austerity C (0-6-0ST) saddle tank locomotives, many were used by the British War Department during their fight against the German army in mainland Western Europe. The NS bought 27 of them just after World War II. They had been built by the Hunslet Engine Company (12), WG Bagnall (3), Robert Stephenson & Hawthorns (RSH) (6) and Hudswell Clarke (6).
