But is there any reason why the current track from Westferry to West
India couldn't be left in place for emergencies and quiet times?

1. There isn't a current track from Westferry to West India Quay
(apart from the flyover)
2. At time of writing, there isn't a current track from West India
Quay to Westferry of any kind (apart from going the wrong way over the
flyover).

Ah well. *If they can describe a derailment as a broken down train, I
spose they can describe a viaduct gone as overrunning engineering
works ...

3. The flyover and dive-under route avoiding West India Quay will only
be used at peak times.

Ah right. *That makes sense.

4. It turns out I was completely wrong about the interim state.
They're going to turn Westferry Junction into a flat junction and
demolish the flyover, exactly as you described.

Ah right, but the flat junction is only used when the flyunder isn't
used, ie at quieter times, or that would have been odd (moving the
conflict from one place to another).

But the diagram looks like I'm wrong about demolishing the flyover and
that the peak southbound trains will go over the flyover and then
under the flyunder. *If what you said was wrong, it was only about the
other route being interim.

Or maybe it will be a different flyover. *I am not clear on what's
being lowered; presumably the current eastern end of the flyover so it
can go under instead of heading for West India Quay.

The new flat junction splitting between Poplar and the West Curve
seems to be in place, but not all the (will be two-way) track is in
place yet between there and West India Quay. The flyover to West
India Quay is still there, but out of use.

Both outer platforms at West India Quay are boarded up and out of use.

The track has been removed from the outer southbound platform at West
India Quay, and the single-track viaduct leading to that platform from
Poplar has had a section demolished.

So I am guessing that, from next week, the new flat junction will
become the route to and from West India Quay from and to Westferry,
while work proceeds on diverting the track from the flyover to the
flyunder, which is yet to be built.
