I've just noticed that Google maps has hi-res imagery for outside London. But it's not new. In fact, it is at least 5 years old, as you can see that the canopy on the platforms to the west isn't yet completed, yet by March 2002 it was all in place. I think it's pre October 2001, as I can't see the shadow of signals 6 & 7 (Third Quarter 2001). I will update if I can find a photo (or information) on when the canopy was in the state Google shows.
