The journey from Cockfosters to Arnos is a bit of a chore sometimes.
During the morning peak (and leading up to it) you will have trains
coming in to service from Cockfosters (east end), Cockfosters (west end)
and reversers at Arnos Grove, all to get the 28 trains per hour through
the centre section.

A mere 24 trains per hour currently. You ought to be able to manage 28
IMHO. In fact you had a 27 tph timetable a few years ago, and I never
had a credible explanation of why it was abandoned. I fail to see why
the Picc can't do better than 24 tph when the District/Circle does 28
despite the extra complications of its network.

Ooh, I'm not getting into this one other than I accept it's not 28 (it
was a guess on my part as I haven't actually counted them); next you'll
be telling me we should stop at Turnham Green all day though
