The London and North Western Railway (LNWR) Class B was a class of 0-8-0 steam locomotives introduced in 1901. A development of the three-cylinder compound Class A (though this letter classification was not introduced until 1911), they had a 4-cylinder compound arrangement. 170 were built between 1901 and 1904.
