Original sentence: 27 that had been loaned to Nederlandse Spoorwegen were sold to that company in 1947 (NS Class 8800, numbers 8801-27).A total of 337 had been built for the War Department by 1947 (on orders placed during the war), with two further engines having been built for collieries (without the permission of the Ministry of Supply).Around 70 Austerities have been preserved, and they are common on heritage railways.In 1952 the Army needed more locomotives for military depots, so it ordered 14 locomotives to supplement the 90 that it had retained.Several have been painted as LNER Class J94's to represent mainline rather than industrial steam.The Hunslet Engine Company Austerity 0-6-0ST is a steam locomotive designed for shunting.The NCB continued to use Austerities in the 1970s and a small number remained in service until the early 1980s.The class became the standard British shunting locomotive during the Second World War, and production continued until 1964.When the end of the war reduced the need for locomotives, the military started to review its fleet:
Edited sentence: 27 had been loaned to Nederlandse Spoorwegen who bought them in 1947 (NS Class 8800, numbers 8801-27).A total of 337 were built for the War Department by 1947 (on orders placed during the war), with two further engines having been built for collieries (without the permission of the Ministry of Supply).Austerities have become a favourite of the heritage railway scene, and around 70 examples have escaped the cutter's torch.Indeed, the stereotypical image of a small British preserved railway is an Austerity saddle tank hauling 2 or 3 British Railways Mark 1 coaches.Needing more locomotives for military depots, the Army ordered 14 locomotives in 1952 to supplement the original 90 they had retained.Several of these have become faux Class J94, to represent mainline rather than industrial steam.The Austerities continued in industrial use with the NCB into the 1970s with a small number surviving until the early 1980s.The Hunslet Engine Company Austerity 0-6-0ST is a design of steam locomotive designed for shunting.The class became the standard British shunting locomotive during the Second World War, and a total of 485 were built right through until 1964.With the end of the war and then the reduced need for locomotives, the military started to review its fleet:
