I don't think that the Orbirail project will ever run a fully
circular service, because of the potential for serious delays (like
the circle line but infinitely worse). Nothing's decided, AFAIK,
but clockwise services from Clapham Junction may terminate at
Stratford for the Olympics, and at Barking thereafter, although it
has also been suggested that they may (as at present) go no further
than Willesden Junction.

Where have you seen that suggestion? I thought that 8 tph on the North
London Line east of Willesden Junction was a key feature of TfL's
proposals in order to reduce overcrowding on the WJ-Stratford section.
If the CJ-WJ shuttle stays in place, how would they achieve 8 tph east
of
WJ?
