That's partly because there are semi-fasts which skip Palmers Green, and
there are no overtaking opportunities between Stevenage junction and
Alexandra Palace via Palmers Green (although they can start extra trains at
Gordon Hill or Hertford North).

When I met FCC, about a number of issues, I was told that TfL are
working with them to increase the services from Moorgate throughout the
day. No date was given, but the plan is to run a tube-like frequency
ALL day and later into the evenings. I have to assume that TfL (or
perhaps local authorities) will partly fund the move, but didn't ask
about the funding issue.

Another discussion has also boosted my chances of getting a new service
in the morning from Hatfield (a train just for me.. woohoo!!) with a
bit of juggling around of services. May have to wait for the next
timetable but one, but Wagn never managed it in all their years of
service. :-)
