. Potters Bar might be a better location, but their trains don't stop
there yet. If they, or their successors, ever do start stopping their
trains there, it might be worth considering extending the Jubilee Line
there. But it's not going to become as important a station as Watford
Junction any time in the forseeable future.

Wouldn't it be easier to extend the Piccadilly there in that eventuality
as it's just up the road from Cockfosters?
