> London is its own kind of beast with the tube/overground To do well in London you really have to know the city (or at least the areas around your start/end points). Especially as you get towards the centre of London, there are lots of opportunities for "cheating" (i.e. getting out and walking is much more efficient than going to your actual destination station, or, worse, changing trains). If you want to go that extra step, memorising the tube map (or at least the central areas) also helps because then you can consider your re-routing options based on the actual live status of the tube (I say "actual status" because London Underground ALWAYS lie about the actual status .... i.e. they will always declare "good service" until they really can't avoid admitting the truth, by which time the service is truly up the spout)
