Still seems a strange terminus for Crossrail though, Dartford or even

I suspect it's purely as it's the first available station after the
river crossing where it can do so. The route is apparently safeguarded
to Gravesend, but in the interests of minimising the project (in order
to make it happen) whilst getting the big sections built (the river
crossing to interchange with the existing network for example), Abbey
Wood is where it will terminate.
