LondonTransit Wiring

My District Line train heading west stopped for a minute as we approached our destination at Earls Court station. The London Underground's wiring has always fascinated me and this was a chance for a blip :)  I followed some of the Ryder Cup in France on the internet today.  Our main event was dinner with our friend Liz, whom Marylee has known since her days at Oxford in the 1960s; we ate at a nearby Lebanese restaurant which we know from previous visits. 

The mark on the map is a bit of a guess, since the Underground line is not on the map.
