Extrapolated between the tube stations mostly I think. Some of the "cut and cover" lines have been traced from aerial imagery and on-the-ground observations (they have a visible surface "footprint" due to the construction method, and the fact that you can't easily build big buildings on top of them). The deep lines are pure guess work, with a little artistic license to make the lines nice and curvy. Most of the underground isn't actually underground, so that part is easy!
