LNER Class O6

The London and North Eastern Railway Class O6 was a sub-class of the Stanier Class 8F 2-8-0 heavy freight locomotive, which the War Department had chosen as its standard freight engine. After building 60 for the Railway Executive Committee to LMS order between 1943 and 1945, the LNER chose to build some of the design for itself. Construction was divided between Darlington Works and Doncaster Works, with 25 more subcontracted to the Southern Railway's Brighton Works. Their time in LNER stock was short: the LNER took on the WD Austerity 2-8-0 as its Class O7, and the O6s were taken into LMS stock in 1946 and 1947 and renumbered into the 8705 to 8772 series, so the class was extinct by nationalisation. One Doncaster-built engine, 48518, survives as one of the Barry Ten.
