Ernie - those are indeed the Courtaulds tank locos Wilfred and Patricia, and the photo is taken at Courtaulds factory in Carrickfergus. Belfast Telegraph archives have some similar at a slightly different angle, taken when the pair were moved to a Belfast scrapyard. The GN photos, I initially thought, may be at Maysfields, as the buildings look rather like the electric generating station there, although the tree puzzles me. I have asked my father, who was taking his own photos round these parts at that time! He thinks it’s one end of Grosvenor Road goods yard, where an SG3 and a UG class lasted for some time after the main GN fleet had gone to the flames. According to Norman Johnston’s book, the pair made it to 1968 (the UG) whilst the pictured SG3 no 37 got to 1969, although withdrawn c1965.
