I don't quite follow this. *Both tracks on the West Curve are

India Quay.

Between the flyover and the west curve there's a short section where
the two westbound/northbound tracks run alongside the eastbound/
southbound track from the flyover. The three tracks then go around the
West Curve together and into their respective platforms at West India
Quay. *The plan is to replace the northernmost track with a ramp down
to a diveunder under the East Curve.

That still doesn't seem right. *Surely the northernmost of the three
tracks IS the flyover?



Southbound trains use the flyover. *Is the idea to leave the flyover
in place until the divunder is built (on the space reclaimed from one
side of the West Curve) and then demolish the flyover?

No. The flyover is untouched. Southbound trains will use the West
India Down Viaduct to go over the Beckton Link Vaiduct (as now) then
almost immediately use the new dive under to go under the East Curve
and into Canary Wharf.

That makes sense in itself, but then where would the flyover lead to?

(Reading and re-reading and trying to make sense ...) I think the bit
with three tracks that you mention is right by West India Quay end.
So that would mean that it's the track that comes over the flyover
that then immediately goes down the flyunder.

So that still leaves a mysterious bit of track removal on the
previously two-track section a bit further west. The only way that
could go two-way would be by creating a flat junction on the Westferry
side, which can't be the plan. It was always two north/westbound
tracks which merged, but now merge further east.
