The importance of the destination dictated the motive power selected to haul each portion to their final destinations. Through carriages to East Devon and North Cornwall were invariably hauled by diminutive Drummond M7 tank locomotives, and from 1952, BR Standard Class 3 2-6-2T's; the rest of the train continued behind a Bulleid Light Pacific to Plymouth. The final "ACE" was hauled on 5 September 1964 when the Western Section of the former Southern Railway network was absorbed into the Western Region of British Railways.
