I've noticed some bits of track being taken up recently. *One is the
siding at Mudchute, which probably has to go to make room for a
platform extension.

They're replacing the siding with a third platform.

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.
