London Regional Metro eastern portal and junction
 

Hi all,

I've just got round to looking at the London Regional Metro proposal. It
looks broadly like Crossrail, but i'm puzzled about what happens at the
eastern end. I'm looking at their schematic map:

And seeing that they're proposing that at the eastern end, there's are
underground platforms at Liverpool Street, then the portal, then a
junction where branches split off for the Great Eastern and West Anglia
lines.

Where would this junction be? The map makes it look like it would be next
to the existing GE/WA junction, in Bethnal Green, implying that the portal
would be west of there, but i can't believe there's room there for two
more tracks, a junction, and a flyover (for the LRM WA branch to cross the
GE). Do the LRMists believe differently? Are they actually thinking of
putting the portal and junction somewhere else? If so, where? Why don't
they just send all trains to Stratford, and then send WA services up the
Lea Valley line?

Apologies if this has been covered before here - RTFG would be an entirely
appropriate answer, although some hints as to where the thread was would
be ideal!
