In 1942 Robert A. Riddles designed the J94 Austerity 0-6-0 to meet the country’s shunting needs. The first locomotive was built in 1943 with an eventual 377 being built.
After the war the military kept 90 for their railway system. 75 were sold to the LNER being classified as J94 some with modified coal bunker and extra steps, with others sold for industrial use. Between 1948 and 1964 77 new Austerity locomotives were built for the NCB, which continued in use into the 1970’s with a total of 70 entering preservation.
