What station was used in filming "Hereafter"?

In this trailer at about 2:08 there is a Jubilee Line line diagram, on which the first, second, third and sixth stations are interchanges, suggesting that it is indeed Charing Cross. l can't make out enough of the train to identify it, but it's unlikely to be an '83 if the film was made within the last ten years.

From what I see of the reviews, two key events in the film are the Boxing Day tsunami (although several reviewers refer to it as having been in the South Pacific rather than the Indian Ocean), and the 7/7 bombings - the trailer also includes a shot of the outside of a station I don't recognise, although the signage says [illegible] CROSS STATION.
