Anyone for sitting on the roof?

I nearly forgot: Monday's ES also mentioned this report from the Corporation of London, which you can read if you want (many graphs), but it was summed up nicely in one paragraph by the Standard: It "predicts the number of passengers using the Underground and railways in London will rise by 24% by 2016." And their editorial was headed: "We need Crossrail". Indeed. And quite a bit more investment, or there won't even be standing room.
