The LCDR R class was a class of 0-4-4T locomotives on the London, Chatham and Dover Railway (LCDR). No. 207 (eventually no. 31666) is notable as being the last former LCDR locomotive to be withdrawn from service.^[1] The whole class was fitted with condensing apparatus for working on the Widened Lines.^[2]

For many years the London, Chatham and Dover Railway (LCDR) had favoured the 0-4-4T wheel arrangement for suburban and stopping passenger trains, and when more were required in 1890, consideration was given to ordering a further batch of the existing A2 class 0-4-4T (introduced 1883); it was then decided that a modified design was required.^[3] The R class locomotives were designed by William Kirtley as a development of his earlier A2 class,^[3] and 18 were built by Sharp, Stewart and Company in 1891.^[4][5]

Their LCDR numbers were 199–216, which under the South Eastern and Chatham Railway became 658–675 from 1899.^[4] They were renumbered three more times: to A658–A675 by the Southern Railway (SR) from 1923; to 1658–1675 by the SR from 1931; and to 31658–31675 by British Railways from 1948.

Three (Nos. 1664, 1668 and 1669) were withdrawn in 1940 to provides spares for the others,^[1] and withdrawal of the rest occurred between 1949 and 1955.^[5]
