5519 is passing Dubbers Siding and clay drying kiln, on the left, between Drinnick and Treviscoe on the Parkandillack Branch (which leaves the main line at Burngullow). The roof of Drinnick Mill goods station can just be made out above the roofs of the two sheeted vans. The mineral wagons at the front of the train may contain coal for Treviscoe, whilst the vans are almost certainly empties being taken down to Kernick or bound for the Retew Branch, to be loaded with bagged clay (if the train was loaded it would have merited a second loco). The line to Drinnick branched off to the left just behind the brake van, dropping down to a run round and buffer stops; it then ran back beneath the train (the bridge is just visible around the centre point of the train) to reach Drinnick Dryers - complicated stuff, you need to look at a map of the area!
