When you go northboard on a picc train just leaving
finsbury park station if you look left out of the train
there is a large empty space in the tunnel and what
looks like a small tunnel or cavity disappearing south
from it going back behind the station wall.

According to http://www.geocities.com/Athens/Acro.../ltfinpark.gif ,
the Northbound Picc was not interfered with in the 1960s, so the explanation
being offered by half a dozen people is not the right one.
