Would it be totally impractical for all or most Met journeys to/from
Chesham
to run as through services to Baker Street as opposed to mainly a
branch
shuttle with the odd peak-time run to Aldgate or wherever. Just seems
a
bit
messy compared to most other lines which tend to provide through
services
to
all their extremities.

It would be possible but I doubt enough people use Chesham off-peak to
make
it worthwhile.

Also would it not be feasible for Central Line trains serving Hainault
to
run alternately clockwise/anticlockwise round the Hainault loop and
back
towards the City?

As there would be no terminus there would be nowhere for the trains to
make
up any time and this would decrease reliability.

So how does this work now at the Heathrow end of the Picc

Badly

or, come to that,
on the Circle line?

Very badly.

Which is why "layover" time is built in at Heathrow T12&3 and Aldgate
respectively.
