Same lane, same time and a bit before! Its all paved over now instead of the rocky road and even rockier ledge to stand on. Saw the same thing at Friary, WC and headboard leaving for all points east; late forties and another time a bit later. At the time, I was unaware of the significance of the ACE but the headboard stood out. Sometimes I thought a T9 did the honours as they seemed to be the preferred passenger engine.
