Having visited the new-look station at lunch time, we can confirm: that's one bastard of a roof. Such is the scale and magnificence of St Pancras International, the cleaners will be sweeping up a fine collection of dropped mandibles this evening.
We've compiled a few images of the opening, for those of you who couldn't get there. This place really has to be seen to be believed.
But first a video.

The giant statue of lovers embracing dominates the concourse.
Not everyone was happy. Cyclists staged a protest at the lack of bicycle facilities and dangerous one-way systems around the station.
