There is an exhibition on at the Building Centre Store Street, off Tottentham Court Road showing the designs for the Crossrail stations, plus a very large and snazzy model of London outlining the route and stations. I went yesterday, but if you can't get there have a look at the London Reconnections site where many of the pictures are on display. There is much talk in the exhibition of 'regeneration' and 'urban quarters' around many stations but a fair amount of demolition has also been involved. Nevertheless some of the designs, especially Canary Wharf, look impressive.
