20048 rolls down the gradient at Heap Bridge on 3 July 2011 with the 2J81 13:55 Heywood to Rawtenstall service, during the East Lancashire Railway's Diesel Gala. Strictly speaking the two white discs being displayed here indicate a 1xxx working rather than a 2xxx (although after 1977 with the general abandonment of headcodes, this would have been used). It should really be displaying just the upper white disc for this particular working.
