But why don't they do some similar bribery to get more trains running on

and there are huge gaps in the service.

I think the issue will lie somewhere between DfT and Network Rail. DfT
is more interested in screwing huge premiums out of franchise holders
than it is in getting more trains running or funding an expansion in
infrastructure. The lines out of Kings Cross and Moorgate are pretty
much full in the peaks due to the need to mesh fast, semi fast and local
trains on the tracks alongside GNER, Hull Trains and soon Grand Central.

But those trains don't use the Hertford Loop (the line through Palmers
Green). The section from Alexandra Palace to Finsbury Park might be a
bottleneck, but aren't there extra tracks there?

Yes and where do they then go? Moorgate is a very tight bottleneck and
Kings Cross is pretty much at capacity AIUI. Mr Cowling is complaining
about the peak timetable IIRC.

I was thinking Moorgate. It currently handles 12tph in the peaks;
Brixton has the same layout and manages 30tph. But I suppose it's not
that simple.
