I have only two uses for You Tube and one of them is watching cab view videos of train journeys. I find these fascinating and a recent upload is especially interesting.

I would expect a train movement from Willesden Junction to the ECML to run via Gospel Oak, GOBLIN and the Harringay West Curve, but this video shows there is another way.
