From time to time you hear that old piece of dog-eared doggerel ‘one person can make a difference’, and you think – in Quasimodo’s dreams. If you try to apply this to the North London Line, that fabled clogged artery especially designed to make misery the lives of anyone unfortunate enough to have no alternate means of getting from grim A to grubby B you enter the realms of science fiction. This line is so appalling, even Boxcar Willie refuses to ride it. It makes the Tube look like the TGV. But, standing like a beacon of hope in this twilight gloom of commuter despair is one man who truly has made a difference on the NLL. I speak of John, the Station Manager at Hackney Wick.
