The London and North Western Railway (LNWR) Class F was a class of 2-8-0 steam locomotives in service between 1906 and 1928.

History

George Whale had rebuilt 26 of the Class B compound 0-8-0s with the addition of a leading pony truck between 1904–1908 to what would become Class E in 1911. However, from 1906 10 Class Bs were rebuilt with larger 5 ft 2 in (157 cm) diameter boilers, along with a pair of Class Es (Nos. 1038 and 647) in 1907 and 1908 respectively.

From 1921, the LNWR started rebuilding the Class Fs into Class G1 superheated 0-8-0s, and by the grouping of 1923 six had been rebuilt. The remaining six were allocated the LMS numbers 9610–5. The LMS rebuilt a further four into G1s between 1923 and 1925. The last two were withdrawn and scrapped in 1927 and 1928 without being rebuilt.
