yet another angle
So I've looked out a few slides I took there on Easter Saturday 31-3-1975,which gives a another angle of it, when most London trains were hauled by class 52 locos.
However,before I went onto the flyover I had a word with the duty signalman, and told him what I intended doing, so he was aware of where I was. After taking several photo's, I returned to the box to let him know when I had finished on the flyover, but continued taking pics by the signalbox for a while.
enjoy, cheers JOHN C.
