Isn't this going to mean a whole load of people on the Jubilee Line as they go to Waterloo/Westminster in place of Waterloo East/Charing Cross? Is there room for them? Is this therefore going to mean you can't get on to the Jubilee at London Bridge meaning even more people will try to cram onto the Overground? I can't see that a single extra carriage will make much difference, and I shudder to think what the Canada Water escalator queue will be like.
