King's Cross St. Pancras Tube station is served, if I recall correctly (and Wikipedia confirms), the Victoria, Piccadilly, Northern, Circle, Hammersmith & City, and Metropolitan lines. The first three of these are deep-level lines, with the smaller trains and deeper platforms.
What I need to know is this: do any of the King's Cross trains on those three lines feature "Mind the Gap" announcements? Not all stations do, I know; only the ones where trains fit round curved platforms or don't quite fit for whatever reason. Can anyone confirm that King's Cross is one of them? And I'd love it if anyone knew the exact wording of the announcement: I'm extrapolating from other stations and assuming it's "This is King's Cross St. Pancras. Change here for [all the above lines]. Please mind the gap between the train and the platform." But if I'm wrong, please correct me.
