The London, Midland and Scottish Railway (LMS) Stanier Class 8F is a class of steam locomotives designed for hauling heavy freight. 852 were built between 1935 and 1946 (not all to LMS order), as a freight version of William Stanier's successful Black Five, and the class saw extensive service overseas during and after the Second World War.

Following Stanier’s new designs of express and mixed traffic engines for the LMS he turned his attention to the need for a heavy standard freight engine. The 8F class was introduced in 1935 and the design was a success straight off the drawing board proving itself far superior to the 0-8-0s which had been inherited from the LYR and LNWR.

LMS Stanier Class 8F 8151 (British Railways No. 48151) is a preserved British steam locomotive. 8151 was built at Crewe Works in 1942 by the LMS as one of the 8F Class. Following nationalisation in 1948, 40000 was added to the class's original numbers and so in 1949 it was renumbered to 48151.

This design was intended to fulfil the "Heavy Freight" locomotive requirement given to Stanier when he became CME of the LMS in 1932.

All of the 'Big Four' companies constructed 8Fs for the WD, including the LNER who built sixty 8Fs between June 1943 and September 1945. These were lettered "LMS" and were officially on loan to the LNER until they were replaced by sufficient numbers of O7 'Austerity' 2-8-0s.
