After a brief pause on the Down Slow to allow some units to overtake 47790 restarts 5Z40 passing Acton Bridge. You'll have to excuse the untidy foliage - after a mad dash from my first shot to the bridge I spotted there was a shot from the tree. A second mad dash up the tree, I balance on a branch that god only knows how supported me trying to create a hole through the leaves with one hand and holding the camera in the other whilst 47790 puts her foot down! It all came together though, just!
