This table details the steam locomotives of the Hunslet Austerity 0-6-0ST class that have been preserved on heritage railways. Of the 484 'Austerities' constructed, around 70 have survived into preservation. Although the Hunslet Engine Company were responsible for the design, not all of these locomotives were built by the company. In order to meet wartime demand, Hunslet subcontracted some of the construction to Andrew Barclay Sons & Co., W. G. Bagnall, Hudswell Clarke, Robert Stephenson and Hawthorns and the Vulcan Foundry.
