I popped along to Abbey Wood yesterday, the future Crossrail terminus.
It's moved along quite a bit since my last visit, with both of the
third rail tracks now in their final positions, and quite a bit of
Crossrail track in place near the portal, so here's a few of my
pictures for people who don't frequent the North Kent line:

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.

I think the conclusion was that, because of signalling interference problems
it wasn't possible to route one DC track north of the portal.

Another snag for now is that the only footbridge in use is a very long way
from the stopping position of Up trains.

It's about halfway along the platform. The new station building will be
right at the eastern end of the platforms.
