After a spell at Wath, it moved to the Midland Region in 1967. By then numbered 25278, this loco was the last of its class to receive a general overhaul, at Derby, in 1981 and was officially withdrawn on 15 March 1987. Painted in a two tone green livery and named ‘Sybilla’, at the request of its previous owner Jos de Crau, it can be seen in regular use on NYMR.
