56053 Sir Morgannwg Ganol / County of Mid Glamorgan is spot lit in a small patch of sunshine at Foxhall Junction on 31 July 1986, as it heads westwards along the Great Western Mainline with bitumen tanks, presumably heading for Llandarcy. Instead of sticky black stuff, this loco's previous loads have obviously more of a powdery white nature, judging by the deposits on the roof. Stone from either the Westbury area or Tytherington would be the culprit!
