I've still not quite worked out the rationale behind the Wembley Park
stops during the peak, as the pattern seems a bit inconsistent

AIUI it is related to Met. - Jubilee interchanging with Wembley Park
relieving Finchley Road. If all passengers requiring interchange had
to do this at Finchley Road dwell times of both lines would increase
and/or platform overcrowding would occur at FIR. Yes I am aware there
are both busier and less well laid out interchanges - but if there a
way to provide some relief where possible it is better to do so for
all round journey flexibility.


I understand this for the trains on the 'slow' lines at Wembley Park,
but these all stop anyway. What I can't work out is why only some of
the trains on the 'fast' lines are timetabled to stop. Surely very few
passengers would choose to change at Wembley Park to / from these
trains (if heading in the same direction, i.e. NB to NB) as it would
involve using the footbridge instead of a cross-platform change at
Finchley Road.
