Canning Town DLR junctions

With the extension to LCY well advanced and the conversion of the NLL
between Stratford and Canning Town, what junctions are planned for the
area?

If I've worked it out correctly, there will be four directions DLR
trains can go from Canning Town:

- west to Poplar
- east to Beckton
- east to LCY
- north to Stratford

This means that the following junctions could be built:

- a double flying triangle northwest of the station between the
existing DLR High Level line and the soon-to-be-converted NLL. This
allows DLR services to avoid Canning Town entirely and proceed direct
to Stratford without reversal, as well as allow direct
Stratford-Beckton and Stratford-LCY services, as well as the existing
Poplar-Beckton service

- a double junction, starting just south of the old Low Level NLL
platforms, to connect with the existing junction to LCY (this allows
trains to run to LCY and Beckton from Stratford without going through
the High Level at all)

- a chord from the old NLL platforms to the Beckton line, meeting it
east of the LCY junction (this would prevent a Stratford-LCY service
via the Low Level and would necessitate a trek from the old NLL
platforms to the existing DLR platforms)

Has any information been released on what the proposed traffic flows
and services are and what sort of junctions will be made between the
existing DLR and the NLL to allow DLR trains access? No doubt Clive
Feather (and others) can already explain the feasibility of a flying
triangle at Canning Town...

I don't think there'd be enough space immediately northwest of the
station, you've got the River Lea, two sets of powerlines and the
newly re-done A13 Canning Town flyover in the way!
