They're replacing the siding with a third platform.

Ah right. I am not clear whether there will be extra terminating
trains or Crossharbour terminators will go further south (this might
affect whether they go to Bank or Stratford). Both seemed to be
suggested in the discussion.


But I can't work out what's happening at "W. Curve", where the
junction between the two tracks has been moved east, leaving an unused
section of track up to just before where the line from Poplar joins.

They're creating a diveunder where trains that currently use the
southbound track of the West Curve will be diverted underneath the
East Curve, coming up alongside West India Quay station on its east
side (rejoining too late to have a platform there, in fact). The
northernmost part of the West Curve needs demolishing to achieve this,
so it makes sense for them to keep trains as far to the other side as
possible.

I don't quite follow this. Both tracks on the West Curve are
northbound, one for each platform they might have used leaving West
India Quay.

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?
