. 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?

Yes it would. However the Piccadilly does not venture very far from the
GN, so the benefits would be much lower.

As somebody who grew up in Potters Bar and knows the area reasonably well,
there is also the small question of engineering difficulties and overall
cost. It would need some major earthworks or, more appropriately, tunnelling
(there is the small geographical feature of Stag Hill to contend with.) This
would be a hugely expensive project for little economic gain. It also falls
outside the TfL area. You only have to look at the problems faced by the
rather more practical proposal to join up the Watford branch of the
Metropolitan to Watford Junction, along the former Croxley Green track bed
to see the difficulties that scheme has faced, not least through the
TfL/Hertfordshire CC interface and the different funding regimes.
