BR ex-WD Austerity 2-8-0

The British Railways ex-WD Austerity 2-8-0 was a class of 733 2-8-0 steam locomotives designed for heavy freight. These locomotives of the War Department Austerity 2-8-0 type had been constructed by the War Department as war locomotives in 1943 to 1945. After the war they were surplus, so in 1946 the London and North Eastern Railway bought 200 of them as Class O7 and had taken another 278 on loan by the end of 1947. After nationalisation British Railways purchased 533 more, including all of those on loan, giving the class total of 733. The engines were used almost entirely on freight. The infobox lists the North British Locomotive Company and Vulcan Foundry as builders. None was preserved.
