It will be a faster way to get _thru_ London, instead of just _into_
London.

Who exactly needs to go through london that quickly, everyone in kent/
france can already get through via CTRL/St Pancras - and its only a
couple of stops round the tube if they want to get to paddington/
euston [and vice versa]. So that only leave the people in Anglia, but
north & central Anglia can access kings cross, so that's really just
the people in essex, which is hardly significant in the scale of cross-
london travel.
