D9000 Royal Scots Grey & D9016 Gordon Highlander cross Greenway Viaduct on the Paignton & Dartmouth Railway with the 18:00 Kingswear to Paignton service on 20 June 1992, during the line's Diesel Gala. From the exhaust it seems that D9000 is running on one engine and D9016 is not providing power. Although this is probably not the case, one engine out of the available four would be more than sufficient for a train such as this on a heritage railway!
