Metropolitan Bo-Bo electrics Nos 18 and 7 (both unamed at this date) wait in the engine sidings to the south of Rickmansworth station ready to re-engine trains from Aylesbury in February 1952. At this date the locos did not carry their names as the plates had been removed during a wartime scrap metal drive.
