Tube Map Walks: Watford DC
Today was the turn of another Underground Overground Wombling Free walk - this time the Watford DC line from Watford Junction to Euston. It gets its name from the fact it is powered by direct current, in contrast to the West Coast Main Line, which runs adjacent to it, and is powered by alternating current overhead cables. It was taken over in 2007 from Silverlink which had run it from 1997-2007.
Distance: around 20.5 miles.
