In fact many Hainault trains continue to Woodford where
they reverse and go back the same way.

I'm still left wondering whether they couldn't have clockwise and
anticlockwise journeys connecting together all the stations on the loop and
also allowing people using stations around the mid-section of the loop and
travelling from/to beyond the loop to use the first train regardless of
which direction it goes round the loop. Would this not essentially amount to
an improved frequency for no extra resource? There could still be a few
minutes intermediate stand time at Woodford or wherever for recovery.
