I must admit I don't understand why Crossrail and the North Kent line
have separate island platforms, rather than having the Crossrail pair
between the third rail tracks, thus allowing cross-platform
interchanges. The down third rail track could have been re-routed to
the north of the portal, so that it was on the north, rather than the
south of the new Crossrail pair. With that arrangement, both down
tracks would flank one island platform, and both up platforms the
other. It would save a lot of passengers the hassle of having to cross
from island platform to the other.

Presumably that would require the crossrail tracks to cross the 3rd rail ones
complicating signalling, power supply isolation and causing potential hold
ups on both lines due to a problem on the other.
