The North London Line was unique in being the only Network Rail route to be consistently featured on the London Underground map. 2006 was the last year of operation into North Woolwich by the class 313 EMUs. To record this for posterity,the train operator at the time, Silverlink Trains, allowed Video 125 cameras unrestricted access to train cab and stations along the route. The route was electrified at 25KV overhead to allow vital freight movements around the capital. One of the most unusual stations is that at Willesden Junction, the platforms being positioned above the West Coast Main Line and the affiliated “DC lines” from Euston to Watford. The history of the route is complex but totally fascinating, details of which are related en route by Rob Curling.
