In the 60s and 70s, St Blazey outstationed an 08 at St. Austell to primary shunt the goods yard. Wagon load traffic was still being carried at that time. It also shunted the Motorail. I have a photo of the 08 shunting the loaded car carriers out of the loading siding at St, Austell, then via the up goods loop onto the up main wrong line. The 08 would then go into the old up fish dock next to the Signal box. The train loco then shunted the coaches out of the up back siding then onto the car carriers via the up goods loop. Class 52s were used predominantly, but I did see a Class 42 once. At weekends, when not required, the 08 lived in the fish dock, under the watchful eye of the signalman. D4007 was the regular.
Another duty was the Wenford line clay. They worked between Boscarne Juntion and Wenford dries. Type2s worked the loaded wagons between Boscarne Junction and Bodmin Road, primarily I guess because of the severe gradient. After the withdrawal of passenger services on the Padstow line, Type 2s worked the trip out to Wadebridge. I’ve only seen 25s in photos. The whole line was then worked as a long siding from Bodmin Road. I once saw the returning 08 between Lostwithiel and Par, light engine.
