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 simple addition of a leading pony truck between 1904-1908 to what would from 1911 become Class E. However, from 1906 rebuilds of Class Bs were given a larger 5'2" diameter boilers, and ten were so rebuilt. To these was added a pair of rebuilds of Class Es (Nos 1038 in 1907 and 647 in 1908).
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 to G1s, between 1923-5. The remaining pair were withdrawn in 1927 and 1928 without being rebuilt. None was preserved.
