A Finsbury Park - Camden Town link is something that i really do feel
is missing from the current network, like the Finsbury Park -
Highgate link. You may think that this is because i live in Finsbury
Park, but i couldn't possibly comment.

I haven't drawn the next bit because it would take actual effort ...

Stage 3 extended northwards. After a connection from the GN&CR
(allowing trains from Moorgate to run on to the line), it split into
two: - Under the LNER to north of Bowes Park, where it surfaced. There
would be
tube stations at Hornsey, Harringay, Wood Green, and Bowes Park, and
trains would run to Cuffley, replacing the existing LNER services to
KX. - In tube to Seven Sisters (tube station), then surface and continue
to
Enfield Town, replacing the existing LNER services to Liverpool
Street.

Sounds like a fairly sensible plan, really.

What happened between Stevenage and Cuffley? And on the Southbury
loop?

Between 1919 and 1960 the Southbury Loop had only freight services.
