Shame they didn't stick with plan A to have fully cross platform interchange at Abbey Wood then!
Maybe so, but if Crossrail makes it out to Dartford or Ebbsfleet, or Gravesend, many won't need to change at all. And extending the layout we have at Abbey Wood will be far less disruptive.
London commuters are used to walking up and down stairs, after all most of the tube isn't step free, and for those who can't manage stairs, Abbey Wood is fully step free and London Bridge is too now.
Once again, I really get the feeling that 12tph on the Abbey Wood branch will quickly end up being inadequate.Oh this has been raised for a long time. There are a lot of SE commuters who want the more eastern parts of the city or central London who will disappear now they don't need to change at London Bridge or Cannon St (all Covid dependent on how many "commuters" there are of course!). Abbey Wood will become a considerable interchange for people from around the Dartford area. Journey time really matters in metro world.
