In 1963, the number of buffet cars was reduced to five to reflect falling demand, with units 1031 and 1032 losing the carriages; 1031 was converted to standard 6L (202) formation while 1032 lost another car to replace a damaged car in another unit and ran with two TFKs, downgraded to TSK, from Class 201; the rest of these units were used in the formation of 3R(206) "Tadpole" units 1201-1206. The TSKs were later transferred to a 6S(201) unit and replaced with two standard 6L(202) TSOs and 1032 became another standard Class 202 unit. The two buffet cars removed from the units were stored and later converted for departmental use.
