The link from Whitechapel to the viaduct is part of ELLX Phase 1. The
connection from Dalston Junction to Canonbury, and through running
onto the NLL, is part of Phase 2, so it won't need to happen till much
later.

TfL has requested that the ELLX project team look at (the
costs/benefits of?) connecting the extension at its northern extremity
to the NLL proper - indeed the RUS as published last week refers to
this. In addition, I read somewhere today (can't mind where - sorry)
that the new rolling stock is to be maintained at a new depot in the
New Cross Gate area (dunno where though) which would suggest that a
connection will be necessary to facilitate stock transfer.

In Phase 1, there will be a connection at New Cross Gate (for the West
Croydon - Dalston Junction and Crystal Palace - Dalston Junction
services), so there will be no need for a connection at the north end
just to transfer stock. (However, ISTM that it would make the service
a lot more useful at relatively little cost if through running to the
NLL was done as part of Phase 1.)
