I seem to remember the train in the film was above street level, which makes me
think that bit might have been filmed south of the river, perhaps in Battersea
or Vauxhall. (though locals in Ebury Bridge Road told me the film, at least the
bombed bits, was filmed in Chelsea).
If it was a tube train though, I wonder could it have been on what's now the
Hammersmith, on the elevated stretch, by Latimer Road say?
