I am very surprised by this. I fail to see how they can get 4 tracks
in the alignment immediately south of Tottenham Hale. You have Ferry
Lane estate on one side and industrial and residential units including
the retail park on the other.

The line used to be have more tracks on its east side and most of the
alignment is untouched. Have a look on Google Maps and there's space
for four tracking most of the way to Zone 6, with only a few
obstacles. The area south of Tottenham Hale is clear with the
exception of the bridge under the Goblin, where the second span has
been half-inched by a new road, which would obviously need to be dealt
with.
