Train departs Moorgate, runs via Drayton Park, Finsbury Park (high
level), to Highgate High Level. Splits.
* One part turns right at Park Junction and heads to Ally Pally.
* The other part goes straight ahead and continues to East Finchley (or,
in the peaks, High Barnet).
Reverse the process for southbound trains.

Although it's the first I've heard of this idea. AFAIK, it isn't
mentioned in Northern Wastes, which talks of fourteen trains per
hour from Moorgate via Finsbury Park, seven of which would go to
High Barnet and the other seven to Alexandra Palace.

Knowing you, I'm sure you have source for this.

I certainly did, but I can't right now locate it. This makes me think it
might have been in Underground News (which I don't keep).
