According to an online German report from the set, Michael Gambon, David Yates and Daniel Radcliffe’s double were filming in the Surbiton (a suburban area of London) train station this weekend. Thanks to HPANA we have a small summary of the article (which is in German).

The filming was of Michael Gambon standing on the platform with director David Yates requesting that he redo the scene with less gestures again and again. Large numbers of security staff were everywhere directing people away from the track and directing all questions about the filming to the train stations press office, which was of course closed for the weekend. Additional scenes were to be filmed but again, no one will furnish information as to who will be working this weekend.
