A post on skyscraper city shows the rebuilt platform ends coming together and there is a view from within the station, first I've seen anywhere so far. Note how the country end of the platforms curves towards the right:

Couple of questions.
When the strip foundation trenches for the new pre-fabriated walls are dug, how far down will they have gone? Presumably not all the way down to the brick arches underneath, or do they?
It looks like the very ends of P3/P4 and P5/P6 (at least) will taper to quite a narrow width, presumably if the overall site limitations require this they can still get a dispensation from group standards?
Has anyone heard if there will eventually be any canopies on these platforms, similar to the existing long platforms?
